INDICATIONS AND USAGE

1.1

Treatment of Asthma
ASMANEX® HFA is indicated for the maintenance treatment of asthma as prophylactic therapy in
patients 12 years of age and older.
Important Limitations of Use
 ASMANEX HFA is NOT indicated for the relief of acute bronchospasm.
2

DOSAGE AND ADMINISTRATION

2.1

General
ASMANEX HFA should be administered only by the orally inhaled route [see Instructions for Use in
the Patient Information leaflet]. After each dose, the patient should be advised to rinse his/her mouth with
water without swallowing.
The cap from the mouthpiece of the actuator should be removed before using ASMANEX HFA.
ASMANEX HFA should be primed before using for the first time by releasing 4 test sprays into the
air, away from the face, shaking well before each spray. In cases where the inhaler has not been used for
more than 5 days, prime the inhaler again by releasing 4 test sprays into the air, away from the face,
shaking well before each spray.
The ASMANEX HFA canister should only be used with the ASMANEX HFA actuator. The
ASMANEX HFA actuator should not be used with any other inhalation drug product. Actuators from other
products should not be used with the ASMANEX HFA canister.
2.2

Dosing
ASMANEX HFA should be administered as two inhalations twice daily every day (morning and
evening) by the orally inhaled route.
Shake well prior to each inhalation.
The recommended doses for ASMANEX HFA treatment based on prior asthma therapy are
provided in Table 1.
TABLE 1: Recommended Dosages for ASMANEX HFA Treatment
Previous Therapy

Recommended Dose

Inhaled medium-dose corticosteroids

ASMANEX HFA 100 mcg,
2 inhalations twice daily

Inhaled high-dose corticosteroids

ASMANEX HFA 200 mcg,
2 inhalations twice daily

Oral corticosteroids*

ASMANEX HFA 200 mcg,
2 inhalations twice daily

*For Patients Currently Receiving Chronic Oral Corticosteroid Therapy: Prednisone should be
weaned slowly, beginning after at least 1 week of ASMANEX HFA therapy. Monitor patients carefully for
signs of asthma instability, including serial objective measures of airflow, and for signs of adrenal
insufficiency during steroid taper and following discontinuation of oral corticosteroid therapy [see
Warnings and Precautions (5.4)].
If a dosage regimen of ASMANEX HFA fails to provide adequate control of asthma, the therapeutic
regimen should be re-evaluated and additional therapeutic options, e.g., replacing the current strength of
ASMANEX HFA with a higher strength, initiating an inhaled corticosteroid and long-acting beta2-agonist
combination product, or initiating oral corticosteroids, should be considered.
The maximum daily recommended dose is two inhalations of ASMANEX HFA 200 mcg twice daily
(maximum of 800 mcg a day). If symptoms arise between doses, an inhaled short-acting beta2-agonist
should be taken for immediate relief.
2


Reference ID: 3801102

 The maximum benefit may not be achieved for 1 week or longer after beginning treatment.
Individual patients may experience a variable time to onset and degree of symptom relief. For patients
who do not respond adequately after 2 weeks of therapy, higher strength may provide additional asthma
control.
After asthma stability has been achieved, it is desirable to titrate to the lowest effective dosage to
reduce the possibility of side effects.
3

DOSAGE FORMS AND STRENGTHS
ASMANEX HFA is a pressurized metered dose inhaler that is available in 2 strengths.
ASMANEX HFA 100 mcg delivers 100 mcg of mometasone furoate per actuation.
ASMANEX HFA 200 mcg delivers 200 mcg of mometasone furoate per actuation.

4

CONTRAINDICATIONS

4.1

Status Asthmaticus
ASMANEX HFA is contraindicated in the primary treatment of status asthmaticus or other acute
episodes of asthma where intensive measures are required.
4.2

Hypersensitivity
ASMANEX HFA is contraindicated in patients with known hypersensitivity to mometasone furoate
or any of the ingredients in ASMANEX HFA [see Warnings and Precautions (5.8)].
5

WARNINGS AND PRECAUTIONS

5.1

Deterioration of Asthma and Acute Episodes
ASMANEX HFA is not indicated for the relief of acute symptoms, i.e., as rescue therapy for the
treatment of acute episodes of bronchospasm. An inhaled, short-acting beta2-agonist, not ASMANEX
HFA, should be used to relieve acute symptoms such as shortness of breath. When prescribing
ASMANEX HFA, the physician must also provide the patient with an inhaled, short-acting beta2-agonist
(e.g., albuterol) for treatment of acute symptoms, despite regular twice-daily (morning and evening) use of
ASMANEX HFA. Instruct patients to contact their physician immediately if episodes of asthma that are not
responsive to bronchodilators occur during the course of treatment with ASMANEX HFA. During such
episodes, patients may require therapy with oral corticosteroids.
5.2

Local Effects
In clinical trials, the development of localized infections of the mouth and pharynx with Candida
albicans have occurred in patients treated with ASMANEX HFA. If oropharyngeal candidiasis develops, it
should be treated with appropriate local or systemic (i.e., oral) antifungal therapy while remaining on
treatment with ASMANEX HFA therapy, but at times therapy with ASMANEX HFA may need to be
interrupted. Advise patients to rinse the mouth after inhalation of ASMANEX HFA.
5.3

Immunosuppression
Persons who are using drugs that suppress the immune system are more susceptible to infections
than healthy individuals.
Chickenpox and measles, for example, can have a more serious or even fatal course in susceptible
children or adults using corticosteroids. In such children or adults who have not had these diseases or
who are not properly immunized, particular care should be taken to avoid exposure. How the dose, route,
and duration of corticosteroid administration affect the risk of developing a disseminated infection is not
known. The contribution of the underlying disease and/or prior corticosteroid treatment to the risk is also
not known. If exposed to chickenpox, prophylaxis with varicella zoster immune globulin (VZIG) or pooled
intravenous immunoglobulin (IVIG) may be indicated. If exposed to measles, prophylaxis with pooled
intramuscular immunoglobulin (IG) may be indicated. (See the respective package inserts for complete
VZIG and IG prescribing information.) If chickenpox develops, treatment with antiviral agents may be
considered.
Inhaled corticosteroids should be used with caution, if at all, in patients with active or quiescent
tuberculosis infection of the respiratory tract, untreated systemic fungal, bacterial, viral, or parasitic
infections; or ocular herpes simplex.

3

Reference ID: 3801102

 5.4

Transferring Patients from Systemic Corticosteroid Therapy
Particular care is needed for patients who are transferred from systemically active corticosteroids to
ASMANEX HFA because deaths due to adrenal insufficiency have occurred in asthmatic patients during
and after transfer from systemic corticosteroids to less systemically available inhaled corticosteroids. After
withdrawal from systemic corticosteroids, a number of months are required for recovery of hypothalamicpituitary-adrenal (HPA) function.
Patients who have been previously maintained on 20 mg or more per day of prednisone (or its
equivalent) may be most susceptible, particularly when their systemic corticosteroids have been almost
completely withdrawn. During this period of HPA suppression, patients may exhibit signs and symptoms
of adrenal insufficiency when exposed to trauma, surgery, or infection (particularly gastroenteritis) or
other conditions associated with severe electrolyte loss. Although ASMANEX HFA may improve control of
asthma symptoms during these episodes, in recommended doses it supplies less than normal
physiological amounts of corticosteroid systemically and does NOT provide the mineralocorticoid activity
necessary for coping with these emergencies.
During periods of stress or severe asthma attack, patients who have been withdrawn from systemic
corticosteroids should be instructed to resume oral corticosteroids (in large doses) immediately and to
contact their physicians for further instruction. These patients should also be instructed to carry a medical
identification card indicating that they may need supplementary systemic corticosteroids during periods of
stress or severe asthma attack.
Patients requiring oral or other systemic corticosteroids should be weaned slowly from oral or other
systemic corticosteroid use after transferring to ASMANEX HFA. Lung function (FEV1 or PEF), betaagonist use, and asthma symptoms should be carefully monitored during withdrawal of oral or other
systemic corticosteroids. In addition to monitoring asthma signs and symptoms, patients should be
observed for signs and symptoms of adrenal insufficiency such as fatigue, lassitude, weakness, nausea
and vomiting, and hypotension.
Transfer of patients from systemic corticosteroid therapy to ASMANEX HFA may unmask allergic
conditions previously suppressed by the systemic corticosteroid therapy, e.g., rhinitis, conjunctivitis,
eczema, arthritis, and eosinophilic conditions.
During withdrawal from oral corticosteroids, some patients may experience symptoms of
systemically active corticosteroid withdrawal, e.g., joint and/or muscular pain, lassitude, and depression,
despite maintenance or even improvement of respiratory function.
5.5

Hypercorticism and Adrenal Suppression
ASMANEX HFA will often help control asthma symptoms with less suppression of HPA function
than therapeutically equivalent oral doses of prednisone. Since mometasone furoate is absorbed into the
circulation and can be systemically active at higher doses, the beneficial effects of ASMANEX HFA in
minimizing HPA dysfunction may be expected only when recommended dosages are not exceeded and
individual patients are titrated to the lowest effective dose.
Because of the possibility of systemic absorption of inhaled corticosteroids, patients treated with
ASMANEX HFA should be observed carefully for any evidence of systemic corticosteroid effects.
Particular care should be taken in observing patients postoperatively or during periods of stress for
evidence of inadequate adrenal response.
It is possible that systemic corticosteroid effects such as hypercorticism and adrenal suppression
(including adrenal crisis) may appear in a small number of patients, particularly when mometasone
furoate is administered at higher than recommended doses over prolonged periods of time. If such effects
occur, the dosage of ASMANEX HFA should be reduced slowly, consistent with accepted procedures for
reducing systemic corticosteroids and for management of asthma symptoms.
5.6

Drug Interactions with Strong Cytochrome P450 3A4 Inhibitors
Caution should be exercised when considering the coadministration of ASMANEX HFA with
ketoconazole, and other known strong cytochrome P450 (CYP) isoenzyme 3A4 (CYP3A4) inhibitors (e.g.,
ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir,
telithromycin) because adverse effects related to increased systemic exposure to mometasone furoate
may occur [see Drug Interactions (7.1) and Clinical Pharmacology (12.3)].

4

Reference ID: 3801102

 5.7

Paradoxical Bronchospasm and Upper Airway Symptoms
ASMANEX HFA may produce inhalation induced bronchospasm with an immediate increase in
wheezing after dosing that may be life-threatening. If inhalation induced bronchospasm occurs, it should
be treated immediately with an inhaled, short-acting bronchodilator. ASMANEX HFA should be
discontinued immediately and alternative therapy instituted.
5.8

Hypersensitivity Reactions Including Anaphylaxis
Hypersensitivity reactions such as urticaria, flushing, allergic dermatitis, and bronchospasm, may
occur after administration of ASMANEX HFA. Discontinue ASMANEX HFA if such reactions occur [see
Contraindications (4.2)].
The following additional hypersensitivity reactions, such as rash, pruritus, angioedema, and
anaphylactic reaction, have been reported after administration of mometasone furoate dry powder inhaler
[see Adverse Reactions (6.2)].
5.9

Reduction in Bone Mineral Density
Decreases in bone mineral density (BMD) have been observed with long-term administration of
products containing inhaled corticosteroids, including mometasone furoate. The clinical significance of
small changes in BMD with regard to long-term outcomes, such as fracture, is unknown. Patients with
major risk factors for decreased bone mineral content, such as prolonged immobilization, family history of
osteoporosis, or chronic use of drugs that can reduce bone mass (e.g., anticonvulsants and
corticosteroids) should be monitored and treated with established standards of care.
In a 2-year double-blind study in 103 male and female asthma patients 18 to 50 years of age
previously maintained on bronchodilator therapy (Baseline FEV1 85%-88% predicted), treatment with
mometasone furoate dry powder inhaler 200 mcg twice daily resulted in significant reductions in lumbar
spine (LS) BMD at the end of the treatment period compared to placebo. The mean change from Baseline
to Endpoint in the lumbar spine BMD was -0.015 (-1.43%) for the mometasone furoate dry powder inhaler
group compared to 0.002 (0.25%) for the placebo group. In another 2-year double-blind study in 87 male
and female asthma patients 18 to 50 years of age previously maintained on bronchodilator therapy
(Baseline FEV1 82%-83% predicted), treatment with mometasone furoate dry powder inhaler 400 mcg
twice daily demonstrated no statistically significant changes in lumbar spine BMD at the end of the
treatment period compared to placebo. The mean change from Baseline to Endpoint in the lumbar spine
BMD was -0.018 (-1.57%) for the mometasone furoate group compared to -0.006 (-0.43%) for the
placebo group.
5.10 Effect on Growth
Orally inhaled corticosteroids, including ASMANEX HFA, may cause a reduction in growth velocity
when administered to pediatric patients. Monitor the growth of pediatric patients receiving ASMANEX
HFA routinely (e.g., via stadiometry). To minimize the systemic effects of orally inhaled corticosteroids,
including ASMANEX HFA, titrate each patient’s dose to the lowest dosage that effectively controls his/her
symptoms [see Use in Specific Populations (8.4)].
5.11 Glaucoma and Cataracts
Glaucoma, increased intraocular pressure, and cataracts have been reported following the use of
long-term administration of inhaled corticosteroids, including mometasone furoate. Therefore, close
monitoring is warranted in patients with a change in vision or with a history of increased intraocular
pressure, glaucoma, and/or cataracts [see Adverse Reactions (6)].
6

ADVERSE REACTIONS
Systemic and local corticosteroid use may result in the following:

 Candida albicans infection [see Warnings and Precautions (5.2)]

 Immunosuppression [see Warnings and Precautions (5.3)]

 Hypercorticism and adrenal suppression [see Warnings and Precautions (5.5)]

 Growth effects in pediatrics [see Warnings and Precautions (5.10)]

 Glaucoma and cataracts [see Warnings and Precautions (5.11)]

 6.1

Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates
observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another
drug and may not reflect the rates observed in practice. The safety of ASMANEX HFA was evaluated in 2
randomized placebo and active-controlled trials of 12 and 26 weeks’ duration, conducted as part of a
mometasone furoate/formoterol fumarate combination product asthma program, which enrolled 1509
patients with persistent asthma. Patient ages ranged from 12 to 84 years of age, 41% were male and
59% female, 73% were Caucasian and 27% non-Caucasian. Of the total population enrolled in the 2
trials, 432 patients received two inhalations twice daily of either ASMANEX HFA, 100 mcg or 200
mcg/actuation. In the 26-week trial (Trial 1) 192 patients received two inhalations twice daily of ASMANEX
HFA 100 mcg/actuation and 196 patients received placebo. In the 12 week trial (Trial 2) 240 patients
received two inhalations twice daily of ASMANEX HFA 200 mcg/actuation and 233 and 255 patients
received mometasone furoate and formoterol fumarate 100 mcg/5 mcg and 200 mcg/5 mcg/actuation
combination products, respectively, as comparators.
In these trials, the proportion of patients who discontinued study treatment early due to adverse
reactions was 3% and 2% for ASMANEX HFA 100 and 200 mcg treated patients, respectively, and 4%
for placebo-treated patients. Serious adverse reactions, whether considered drug-related or not by the
investigators, which occurred more frequently in ASMANEX HFA-treated patients included colitis
ulcerative, colonic polyp, chest pain, gastroenteritis, endometriosis, asthma, and hemoptysis; all events
occurred at rates less than 1%.
The incidence of treatment emergent adverse reactions associated with ASMANEX HFA are shown
in Tables 2 and 3. These are based upon data from each of the 2 clinical trials of 12 or 26 weeks in
duration in patients 12 years and older treated with two inhalations twice daily of ASMANEX HFA (100
mcg or 200 mcg), mometasone furoate/formoterol fumarate (100 mcg/5 mcg or 200 mcg/5 mcg), or
placebo.

6.2

Postmarketing Experience

There are no postmarketing adverse experiences reported to date with ASMANEX HFA. However,
the postmarketing safety experience with mometasone furoate dry powder inhaler is relevant to
ASMANEX HFA since they contain the same active ingredient. The following adverse reactions have
been reported during post-approval use of mometasone furoate dry powder inhaler. Because these
reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably
estimate their frequency or establish a causal relationship to drug exposure.
Immune System Disorders: Immediate and delayed hypersensitivity reactions including rash,
pruritus, angioedema and anaphylactic reaction [see Contraindications (4.2) and Warnings and
Precautions (5.8)].
Respiratory, Thoracic and Mediastinal Disorders: Asthma aggravation, which may include
cough, dyspnea, wheezing and bronchospasm.
7

DRUG INTERACTIONS

In clinical trials, concurrent administration of ASMANEX HFA and other drugs, such as short-acting
beta2-agonist and intranasal corticosteroids have not resulted in an increased frequency of adverse drug
reactions. No formal drug interaction studies have been performed with ASMANEX HFA.
7.1

Inhibitors of Cytochrome P450 3A4
The main route of metabolism of corticosteroids, including mometasone furoate, is via CYP3A4.
After oral administration of ketoconazole, a strong inhibitor of CYP3A4, the mean plasma concentration of
orally inhaled mometasone furoate increased. Concomitant administration of CYP3A4 inhibitors may
inhibit the metabolism of, and increase the systemic exposure to, mometasone furoate. Caution should be
exercised when considering the coadministration of ASMANEX HFA with long-term ketoconazole and
other known strong CYP3A4 inhibitors (e.g., ritonavir, atazanavir, clarithromycin, indinavir, itraconazole,
nefazodone, nelfinavir, saquinavir, telithromycin) [see Warnings and Precautions (5.6) and Clinical
Pharmacology (12.3)].
8

USE IN SPECIFIC POPULATIONS

8.1

Pregnancy
Teratogenic Effects: Pregnancy Category C
There are no adequate and well-controlled studies of ASMANEX HFA in pregnant women. Animal
reproduction studies of mometasone furoate in mice, rats, and rabbits revealed evidence of teratogenicity.
Because animal reproduction studies are not always predictive of human response, ASMANEX HFA
should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Teratogenic Effects
When administered to pregnant mice, rats, and rabbits, mometasone furoate increased fetal
malformations and decreased fetal growth (measured by lower fetal weights and/or delayed ossification).
Dystocia and related complications were also observed when mometasone furoate was administered to
rats late in gestation. However, experience with oral corticosteroids suggests that rodents are more prone
to teratogenic effects from corticosteroid exposure than humans.
In a mouse reproduction study, subcutaneous mometasone furoate produced cleft palate at
2
approximately one-third of the maximum recommended daily human dose (MRHD) on a mcg/m basis
and decreased fetal survival at approximately 1 times the MRHD. No toxicity was observed at
approximately one-tenth of the MRHD on a mcg/m2 basis.
In a rat reproduction study, mometasone furoate produced umbilical hernia at topical dermal doses
approximately 6 times the MRHD on a mcg/m2 basis and delays in ossification at approximately 3 times
the MRHD on a mcg/m2 basis.

7

Reference ID: 3801102

 In another study, rats received subcutaneous doses of mometasone furoate throughout pregnancy
or late in gestation. Treated animals had prolonged and difficult labor, fewer live births, lower birth weight,
and reduced early pup survival at a dose that was approximately 8 times the MRHD on an area under the
curve (AUC) basis. Similar effects were not observed at approximately 4 times MRHD on an AUC basis.
In rabbits, mometasone furoate caused multiple malformations (e.g., flexed front paws, gallbladder
agenesis, umbilical hernia, hydrocephaly) at topical dermal doses approximately 3 times the MRHD on a
2
mcg/m basis. In an oral study, mometasone furoate increased resorptions and caused cleft palate and/or
head malformations (hydrocephaly and domed head) at a dose less than the MRHD based on AUC. At a
dose approximately 2 times the MRHD based on AUC, most litters were aborted or resorbed [see
Nonclinical Toxicology (13.2)].
Nonteratogenic Effects
Hypoadrenalism may occur in infants born to women receiving corticosteroids during pregnancy.
Infants born to mothers taking substantial corticosteroid doses during pregnancy should be monitored for
signs of hypoadrenalism.
8.2

Labor and Delivery
There are no adequate and well-controlled human studies that have studied the effects of
ASMANEX HFA during labor and delivery.
8.3

Nursing Mothers
It is not known whether ASMANEX HFA is excreted in human milk. Because other corticosteroids
are excreted in human milk, caution should be exercised when ASMANEX HFA is administered to a
nursing woman.
Since there are no data from well-controlled human studies on the use of ASMANEX HFA on
nursing mothers, a decision should be made whether to discontinue nursing or to discontinue ASMANEX
HFA, taking into account the importance of ASMANEX HFA to the mother.
8.4

Pediatric Use
The safety and effectiveness of ASMANEX HFA have been established in patients 12 years of age
and older in 2 clinical trials of 12 and 26 weeks in duration. In the 2 clinical trials, 32 patients 12 to 17
years of age were treated with ASMANEX HFA. No overall differences in effectiveness were observed
between patients in this age group compared to those observed in patients 18 years of age and older.
There were no obvious differences in the type or frequency of adverse drug reactions reported in this age
group compared to patients 18 years of age and older. The safety and efficacy of ASMANEX HFA have
not been established in children less than 12 years of age.
Controlled clinical studies have shown that inhaled corticosteroids may cause a reduction in growth
velocity in pediatric patients. In these studies, the mean reduction in growth velocity was approximately 1
cm per year (range 0.3 to 1.8 per year) and appears to depend upon dose and duration of exposure. This
effect was observed in the absence of laboratory evidence of HPA axis suppression, suggesting that
growth velocity is a more sensitive indicator of systemic corticosteroid exposure in pediatric patients than
some commonly used tests of HPA axis function. The long-term effects of this reduction in growth velocity
associated with orally inhaled corticosteroids, including the impact on final adult height, are unknown. The
potential for "catch-up" growth following discontinuation of treatment with orally inhaled corticosteroids
has not been adequately studied.
The growth of children and adolescents receiving orally inhaled corticosteroids, including
ASMANEX HFA, should be monitored routinely (e.g., via stadiometry). If a child or adolescent on any
corticosteroid appears to have growth suppression, the possibility that he/she is particularly sensitive to
this effect should be considered. The potential growth effects of prolonged treatment should be weighed
against clinical benefits obtained and the risks associated with alternative therapies. To minimize the
systemic effects of orally inhaled corticosteroids, including ASMANEX HFA, each patient should be
titrated to his/her lowest effective dose [see Dosage and Administration (2.2)].
8.5

Geriatric Use
A total of 38 patients 65 years of age and older (3 of whom were 75 years and older) have been
treated with ASMANEX HFA in 2 clinical trials of 12 and 26 weeks in duration. No overall differences in

8

Reference ID: 3801102

 safety or effectiveness were observed between these patients and younger patients, but greater
sensitivity of some older individuals cannot be ruled out. Based on available data for ASMANEX HFA, no
adjustment of dosage in geriatric patients is warranted.
8.6

Hepatic Impairment
Concentrations of mometasone furoate appear to increase with severity of hepatic impairment [see
Clinical Pharmacology (12.3)].
10

OVERDOSAGE

Chronic overdosage may result in signs/symptoms of hypercorticism [see Warnings and
Precautions (5.5)]. Single oral doses up to 8000 mcg of mometasone furoate have been studied on
human volunteers with no adverse reactions reported.
11

DESCRIPTION

ASMANEX HFA is a metered dose inhaler for oral inhalation only, consisting of 100 mcg and 200
mcg of mometasone furoate per actuation.
Mometasone furoate, the active component of ASMANEX HFA, is a corticosteroid having the
chemical name 9,21-dichloro-11(Beta),17-dihydroxy-16 (alpha)-methylpregna-1,4-diene-3,20-dione 17-(2­
furoate) with the following chemical structure:

Mometasone furoate is a white powder with an empirical formula of C27H30Cl2O6, and molecular
weight 521.44. It is practically insoluble in water; slightly soluble in methanol, ethanol, and isopropanol;
soluble in acetone.
Each ASMANEX HFA 100 mcg and 200 mcg is a hydrofluoroalkane (HFA-227: 1,1,1,2,3,3,3­
heptafluoropropane) propelled pressurized metered dose inhaler containing sufficient amount of drug for
120 actuations [see How Supplied/Storage and Handling (16)]. After priming, each actuation of the inhaler
delivers 115 or 225 mcg of mometasone furoate in 69.6 mg of suspension from the valve and delivers
100 or 200 mcg of mometasone furoate from the actuator. The actual amount of drug delivered to the
lung may depend on patient factors, such as the coordination between actuation of the device and
inspiration through the delivery system. ASMANEX HFA also contains ethanol as a cosolvent and oleic
acid as a surfactant.
ASMANEX HFA should be primed before using for the first time by releasing 4 test sprays into the
air, away from the face, shaking well before each spray. In cases where the inhaler has not been used for
more than 5 days, prime the inhaler again by releasing 4 test sprays into the air, away from the face,
shaking well before each spray.

CLINICAL PHARMACOLOGY

12.1 Mechanism of Action
Mometasone furoate is a corticosteroid demonstrating potent anti-inflammatory activity. The precise
mechanism of corticosteroid action on asthma is not known. Inflammation is an important component in
the pathogenesis of asthma. Corticosteroids have been shown to have a wide range of inhibitory effects
on multiple cell types (e.g., mast cells, eosinophils, neutrophils, macrophages, and lymphocytes) and
mediators (e.g., histamine, eicosanoids, leukotrienes, and cytokines) involved in inflammation and in the
asthmatic response. These anti-inflammatory actions of corticosteroids may contribute to their efficacy in
asthma.
Mometasone furoate has been shown in vitro to exhibit a binding affinity for the human
glucocorticoid receptor, which is approximately 12 times that of dexamethasone, 7 times that of
triamcinolone acetonide, 5 times that of budesonide, and 1.5 times that of fluticasone. The clinical
significance of these findings is unknown.

 12.2 Pharmacodynamics
HPA Axis Effects
The effects of inhaled mometasone furoate administered via ASMANEX HFA on adrenal function
have not been directly evaluated. However, the effects of inhaled mometasone furoate, administered as
part of a mometasone furoate/formoterol fumarate inhalation aerosol combination product, on adrenal
function were evaluated in two clinical trials in patients with asthma. As no evidence of a pharmacokinetic
drug interaction between mometasone furoate and formoterol was observed when the two drugs were
administered in combination, the HPA axis effects from the combination product are applicable to
ASMANEX HFA. For the mometasone furoate/formoterol fumarate combination product clinical program,
HPA-axis function was assessed by 24-hour plasma cortisol AUC. Although both these trials have openlabel design and contain a small number of subjects per treatment arm, results from these trials taken
together demonstrated suppression of 24-hour plasma cortisol AUC for the combination mometasone
furoate/formoterol fumarate 200 mcg/5 mcg compared to placebo consistent with the known systemic
effects of inhaled corticosteroid.
In a 42-day, open-label, placebo- and active-controlled study, the mean change from baseline
plasma cortisol AUC(0-24 hr) was 8%, 22% and 34% lower compared to placebo for the mometasone
furoate/formoterol fumarate 100 mcg/5 mcg (n=13), mometasone furoate/formoterol fumarate 200 mcg/5
mcg (n=15) and fluticasone propionate/salmeterol xinafoate 230 mcg/21 mcg (n=16) treatment groups,
respectively.
In a 52-week, open-label safety study, the mean plasma cortisol AUC(0-24 hr) was 2.2%, 29.6%,
16.7%, and 32.2% lower from baseline for the mometasone furoate/formoterol fumarate 100 mcg/5 mcg
(n=18), mometasone furoate/formoterol fumarate 200 mcg/5 mcg (n=20), fluticasone
propionate/salmeterol xinafoate 125/25 mcg (n=8), and fluticasone propionate/salmeterol xinafoate
250/25 mcg (n=11) treatment groups, respectively.
The potential effect of mometasone furoate via a dry powder inhaler (DPI) on the HPA axis was
also assessed in a 29-day study. A total of 64 adult patients with mild to moderate asthma were
randomized to one of 4 treatment groups: mometasone furoate DPI 440 mcg twice daily, mometasone
furoate DPI 880 mcg twice daily, oral prednisone 10 mg once daily, or placebo. The 30-minute postCosyntropin stimulation serum cortisol concentration on Day 29 was 23.2 mcg/dL for the mometasone
furoate DPI 440 mcg twice daily group and 20.8 mcg/dL for the mometasone furoate DPI 880 mcg twice
daily group, compared to 14.5 mcg/dL for the oral prednisone 10 mg group and 25 mcg/dL for the placebo
group. The difference between mometasone furoate DPI 880 mcg twice daily (twice the maximum
recommended dose) and placebo was statistically significant.
12.3 Pharmacokinetics
As no evidence of a pharmacokinetic drug interaction between mometasone furoate and formoterol
was observed when the two drugs were administered from a mometasone furoate/formoterol fumarate
combination product, the pharmacokinetics information from the combination product is applicable to
ASMANEX HFA.
Absorption
Healthy Subjects: Following oral inhalation of single doses of ASMANEX HFA, mometasone furoate
was absorbed in healthy subjects with median Tmax values ranging from 0.50 to 2 hours. Following singledose administration of higher than recommended dose of ASMANEX HFA (4 inhalations of ASMANEX
HFA 200 mcg) in healthy subjects, the arithmetic mean (CV%) Cmax and AUC(0-tf) values for mometasone
furoate were 53 (102) pg/mL and 992 (80) pg•hr/mL, respectively. Studies using oral dosing of labeled
and unlabeled drug have demonstrated that the oral systemic bioavailability of mometasone furoate is
negligible (<1%).
Asthma Patients: Following oral inhalation of single and multiple doses of the mometasone
furoate/formoterol fumarate combination product, mometasone furoate was absorbed in asthma patients
with median Tmax values ranging from 1 to 2 hours. Following single-dose administration of mometasone
furoate/formoterol fumarate 400 mcg/10 mcg, the arithmetic mean (CV%) Cmax and AUC(0-12 hr) values for
mometasone furoate were 20 (88) pg/mL and 170 (94) pg•hr/mL, respectively, while the corresponding
estimates following twice daily dosing of mometasone furoate/formoterol fumarate 400 mcg/10 mcg at
steady-state were 60 (36) pg/mL and 577 (40) pg•hr/mL.

Reference ID: 3801102

 Distribution
Based on the study employing a 1000 mcg inhaled dose of tritiated mometasone furoate inhalation
powder in humans, no appreciable accumulation of mometasone furoate in the red blood cells was found.
Following an intravenous 400 mcg dose of mometasone furoate, the plasma concentrations showed a
biphasic decline, with a mean steady-state volume of distribution of 152 liters. The in vitro protein binding
for mometasone furoate was reported to be 98% to 99% (in a concentration range of 5 to 500 ng/mL).
Metabolism
Studies have shown that mometasone furoate is primarily and extensively metabolized in the liver
of all species investigated and undergoes extensive metabolism to multiple metabolites. In vitro studies
have confirmed the primary role of human liver CYP3A4 in the metabolism of this compound; however, no
major metabolites were identified. Human liver CYP3A4 metabolizes mometasone furoate to 6-beta
hydroxy mometasone furoate.
Excretion
Following an intravenous dosing, the terminal half-life was reported to be about 5 hours. Following
the inhaled dose of tritiated 1000 mcg mometasone furoate, the radioactivity is excreted mainly in the
feces (a mean of 74%), and to a small extent in the urine (a mean of 8%) up to 7 days. No radioactivity
was associated with unchanged mometasone furoate in the urine. Absorbed mometasone furoate is
cleared from plasma at a rate of approximately 12.5 mL/min/kg, independent of dose. The effective t½ for
mometasone furoate following inhalation with DULERA was 25 hours in healthy subjects and in patients
with asthma.
Special Populations
Hepatic/Renal Impairment: There are no data regarding the specific use of ASMANEX HFA in
patients with hepatic or renal impairment.
A study evaluating the administration of a single inhaled dose of 400 mcg mometasone furoate by a
dry powder inhaler to subjects with mild (n=4), moderate (n=4), and severe (n=4) hepatic impairment
resulted in only 1 or 2 subjects in each group having detectable peak plasma concentrations of
mometasone furoate (ranging from 50-105 pg/mL). The observed peak plasma concentrations appear to
increase with severity of hepatic impairment; however, the numbers of detectable levels were few.
Gender and Race: Specific studies to examine the effects of gender and race on the
pharmacokinetics of ASMANEX HFA have not been specifically studied.
Geriatrics: The pharmacokinetics of ASMANEX HFA have not been specifically studied in the
elderly population.
Drug-Drug Interactions
A single-dose crossover study was conducted to compare the pharmacokinetics of 4 inhalations of
the following: mometasone furoate MDI, formoterol MDI, mometasone furoate/formoterol fumarate MDI
combination product, and mometasone furoate MDI plus formoterol fumarate MDI administered
concurrently. The results of the study indicated that there was no evidence of a pharmacokinetic
interaction between mometasone furoate and formoterol.
Inhibitors of Cytochrome P450 Enzymes: Ketoconazole: In a drug interaction study, an inhaled
dose of mometasone furoate 400 mcg delivered by a dry powder inhaler was given to 24 healthy subjects
twice daily for 9 days and ketoconazole 200 mg (as well as placebo) were given twice daily concomitantly
on Days 4 to 9. Mometasone furoate plasma concentrations were <150 pg/mL on Day 3 prior to
coadministration of ketoconazole or placebo. Following concomitant administration of ketoconazole, 4 out
of 12 subjects in the ketoconazole treatment group (n=12) had peak plasma concentrations of
mometasone furoate >200 pg/mL on Day 9 (211-324 pg/mL). Mometasone furoate plasma levels
appeared to increase and plasma cortisol levels appeared to decrease upon concomitant administration
of ketoconazole.

NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
In a 2-year carcinogenicity study in Sprague Dawley rats, mometasone furoate demonstrated no
statistically significant increase in the incidence of tumors at inhalation doses up to 67 mcg/kg
(approximately 14 times the MRHD on an AUC basis). In a 19-month carcinogenicity study in Swiss CD-1
mice, mometasone furoate demonstrated no statistically significant increase in the incidence of tumors at
inhalation doses up to 160 mcg/kg (approximately 9 times the MRHD on an AUC basis).
Mometasone furoate increased chromosomal aberrations in an in vitro Chinese hamster ovary cell
assay, but did not have this effect in an in vitro Chinese hamster lung cell assay. Mometasone furoate
was not mutagenic in the Ames test or mouse lymphoma assay, and was not clastogenic in an in vivo
mouse micronucleus assay, a rat bone marrow chromosomal aberration assay, or a mouse male germcell chromosomal aberration assay. Mometasone furoate also did not induce unscheduled DNA synthesis
in vivo in rat hepatocytes.
In reproductive studies in rats, impairment of fertility was not produced by subcutaneous doses up
to 15 mcg/kg (approximately 8 times the MRHD on an AUC basis).
13.2 Animal Toxicology and/or Pharmacology
Reproductive Toxicology Studies
In mice, mometasone furoate caused cleft palate at subcutaneous doses of 60 mcg/kg and above
2
(approximately one-third of the maximum recommended human dose MRHD on a mcg/m basis). Fetal
2
survival was reduced at 180 mcg/kg (approximately equal to the MRHD on a mcg/m basis). No toxicity
was observed at 20 mcg/kg (approximately one-tenth of the MRHD on a mcg/m2 basis).
In rats, mometasone furoate produced umbilical hernia at topical dermal doses of 600 mcg/kg and
above (approximately 6 times the MRHD on a mcg/m2 basis). A dose of 300 mcg/kg (approximately 3
times the MRHD on a mcg/m2 basis) produced delays in ossification, but no malformations.
When rats received subcutaneous doses of mometasone furoate throughout pregnancy or during
the later stages of pregnancy, 15 mcg/kg (approximately 8 times the MRHD on an AUC basis) caused
prolonged and difficult labor and reduced the number of live births, birth weight, and early pup survival.
Similar effects were not observed at 7.5 mcg/kg (approximately 4 times the MRHD on an AUC basis).
In rabbits, mometasone furoate caused multiple malformations (e.g., flexed front paws, gallbladder
agenesis, umbilical hernia, hydrocephaly) at topical dermal doses of 150 mcg/kg and above
(approximately 3 times the MRHD on a mcg/m2 basis). In an oral study, mometasone furoate increased
resorptions and caused cleft palate and/or head malformations (hydrocephaly and domed head) at 700
mcg/kg (less than the MRHD on an AUC basis). At 2800 mcg/kg (approximately 2 times the MRHD on an
AUC basis) most litters were aborted or resorbed. No toxicity was observed at 140 mcg/kg (less than the
MRHD on an AUC basis).

CLINICAL STUDIES

14.1 Asthma
The safety and efficacy of ASMANEX HFA was demonstrated in two randomized, double-blind,
placebo- or active-controlled multi-center clinical trials of 12 and 26 weeks’ duration, conducted as part of
a mometasone furoate/formoterol fumarate 100/5 mcg or 200/5 mcg combination product development
program. A total of 1509 patients 12 years of age and older with persistent asthma (mean baseline FEV1
of 66% to 73% predicted) were evaluated.
Trial 1: Clinical Trial with ASMANEX HFA 100 mcg
This 26-week, placebo-controlled trial conducted as part of a mometasone furoate/formoterol
fumarate combination product asthma program evaluated 781 patients 12 years of age and older. Of
these patients, 192 patients received ASMANEX HFA 100 mcg and 196 patients received placebo, each
administered as 2 inhalations twice daily by metered dose inhalation aerosols. All other maintenance
therapies were discontinued. The study included a 2- to 3-week run-in period with ASMANEX HFA 100
mcg, 2 inhalations twice daily. Patients ranged from 12 to 76 years of age, 41% were male and 59%
female, and 72% were Caucasian and 28% non-Caucasian. Patients had persistent asthma and were not
well controlled on medium dose of inhaled corticosteroids prior to randomization. Mean FEV1 and mean
percent predicted FEV1 were similar among all treatment groups (2.33 L, 73%). Thirteen (7%) patients

12

Reference ID: 3801102

 receiving ASMANEX HFA 100 mcg and 46 (23%) patients receiving placebo discontinued the study early
due to treatment failure.
The change in mean trough FEV1 from baseline to Week 12 compared to placebo was assessed to
evaluate the efficacy of ASMANEX HFA 100 mcg. The change from baseline to week 12 in the mean
trough FEV1 was greater among patients receiving ASMANEX HFA 100 mcg 2 inhalations twice daily
than among those receiving placebo (treatment difference from placebo 0.12 L and 95% confidence
interval [0.05, 0.20]).
Clinically judged deteriorations in asthma or reductions in lung function were also assessed to
evaluate the efficacy of ASMANEX HFA 100 mcg. Deteriorations in asthma were defined as any of the
following: a 20% decrease in FEV1; a 30% decrease in PEF on two or more consecutive days; emergency
treatment, hospitalization, or treatment with systemic corticosteroids or other asthma medications not
allowed per protocol. Sixty-five (34%) patients who received ASMANEX HFA 100 mcg reported an event
compared to 109 (56%) patients who received placebo.
Treatment of asthma patients with ASMANEX HFA 100 mcg, two inhalations twice daily also
resulted in fewer nocturnal awakenings and improved morning peak flow compared to those who received
placebo.
Trial 2: Clinical Trial with ASMANEX HFA 200 mcg
This 12-week randomized, double-blind, active-controlled trial also conducted as part of a
mometasone furoate/formoterol fumarate combination product asthma program evaluated a total of 728
patients 12 years of age and older comparing ASMANEX HFA 200 mcg (n=240 patients), mometasone
furoate/formoterol fumarate 200 mcg/5 mcg (n=255 patients), and mometasone furoate/formoterol
fumarate 100 mcg/5 mcg (n=233 patients), each administered as 2 inhalations twice daily by metered
dose inhalation aerosols. All other maintenance therapies were discontinued. This trial included a 2- to 3­
week run-in period with ASMANEX HFA 200 mcg, 2 inhalations twice daily. Patients had persistent
asthma and were uncontrolled on high-dose inhaled corticosteroids prior to study entry. Patients ranged
from 12 to 84 years of age, 44% were male and 56% female, and 89% were Caucasian and 11% nonCaucasian. Mean FEV1 and mean percent predicted FEV1 values were similar among all treatment
groups (2.05 L, 66%). The number of patients who discontinued the trial early due to treatment failure
were 11 (5%) in the mometasone furoate/formoterol fumarate 100 mcg/5 mcg group, 8 (3%) in the
mometasone furoate/formoterol fumarate 200 mcg/5 mcg group, and 13 (5%) in the ASMANEX HFA 200
mcg group.
In order to assess the added benefit of a higher dose of mometasone in the 200 mcg/actuation
mometasone furoate product compared to the lower dose 100 mcg/actuation product, trough FEV1 at 12
weeks was compared between the combination mometasone furoate/formoterol fumarate 200 mcg/5 mcg
and 100 mcg/5 mcg treatment groups as a secondary endpoint. Improvement in trough FEV1 from
baseline to week 12 in patients who received mometasone furoate 200 mcg in combination with
formoterol fumarate 5 mcg was numerically greater than among patients who received mometasone
furoate 100 mcg in combination with formoterol fumarate 5 mcg (treatment difference of 0.05 L and 95%
confidence interval [-0.02, 0.10]).
Other Studies
In addition to Trial 1 and Trial 2, the safety and efficacy of mometasone furoate MDI 100 mcg and
200 mcg, in comparison to placebo were demonstrated in three other 12-week, placebo-controlled trials
which evaluated the mean change in FEV1 from baseline as a primary endpoint.

HOW SUPPLIED/STORAGE AND HANDLING

16.1 How Supplied
ASMANEX HFA is available in two strengths and supplied in the following package size (Table 4):

13

Reference ID: 3801102

 Table 4
Package

NDC

ASMANEX HFA 100 mcg

0085-4333-01

120 metered actuations
ASMANEX HFA 200 mcg

0085-4334-01

120 metered actuations
Each strength is supplied as a pressurized aluminum canister that has a blue plastic actuator
integrated with a dose counter and a pink dust cap. Each canister has a net fill weight of 13 grams. Each
inhaler is placed into a carton. Each carton contains 1 inhaler.
Initially the dose counter will display “124” actuations. After the initial priming with 4 actuations, the
dose counter will read “120” and the inhaler is now ready for use.
16.2 Storage and Handling
The ASMANEX HFA canister should only be used with the ASMANEX HFA actuator. The
ASMANEX HFA actuator should not be used with any other inhalation drug product. Actuators from other
products should not be used with the ASMANEX HFA canister.
The canister should not be removed from the actuator because the correct amount of medication
may not be discharged; the dose counter may not function properly; reinsertion may cause the dose
counter to count down by 1 and discharge a puff.
The correct amount of medication in each inhalation cannot be ensured after the labeled number of
actuations from the canister has been used, even though the inhaler may not feel completely empty and
may continue to operate. The inhaler should be discarded when the labeled number of actuations has
been used (the dose counter will read “0").
Store at controlled room temperature 20-25°C (68-77°F); excursions permitted to 15-30°C (59­
86°F) [see USP Controlled Room Temperature].
For best results, the canister should be at room temperature before use. Shake well and remove
the cap from the mouthpiece of the actuator before using. Keep out of reach of children. Avoid spraying in
eyes.
Contents Under Pressure: Do not puncture. Do not use or store near heat or open flame. Exposure
to temperatures above 120°F may cause bursting. Never throw container into fire or incinerator.
17

PATIENT COUNSELING INFORMATION

Advise the patient to read the FDA-approved patient labeling (Patient Information and Instructions
for Use).
Not for Acute Symptoms
Advise patients that ASMANEX HFA is not indicated to relieve acute asthma symptoms, and extra
doses should not be used for that purpose. ASMANEX HFA is not a bronchodilator and should not be
used to treat status asthmaticus or to relieve acute asthma symptoms. Acute asthma symptoms should
be treated with an inhaled, short-acting beta2-agonist such as albuterol. Prescribe the patient with such
medication and instruct the patient in how it should be used [see Warnings and Precautions (5.1)].
Instruct patients to seek medical attention immediately if they experience any of the following:
 If their symptoms worsen
 Significant decrease in lung function as outlined by the physician
 If they need more inhalations of a short-acting beta2-agonist than usual
Advise patients not to increase the dose or frequency of ASMANEX HFA. The daily dosage of
ASMANEX HFA should not exceed two inhalations twice daily. If they miss a dose, instruct patients to
take their next dose at the same time they normally do.
Advise patients not to stop or reduce ASMANEX HFA therapy without physician/provider guidance
since symptoms may recur after discontinuation.

14

Reference ID: 3801102

 Local Effects
Advise patients that localized infections with Candida albicans occurred in the mouth and pharynx
in some patients. If oropharyngeal candidiasis develops, it should be treated with appropriate local or
systemic (i.e., oral) antifungal therapy while still continuing with ASMANEX HFA therapy, but at times
therapy with ASMANEX HFA may need to be temporarily interrupted under close medical supervision.
Advise patients to rinse the mouth after inhalation of ASMANEX HFA [see Warnings and Precautions
(5.2)].
Immunosuppression
Warn patients who are on immunosuppressant doses of corticosteroids to avoid exposure to
chickenpox or measles and, if exposed, to consult their physician without delay. Inform patients of
potential worsening of existing tuberculosis, fungal, bacterial, viral, or parasitic infections, or ocular herpes
simplex [see Warnings and Precautions (5.3)].
Hypercorticism and Adrenal Suppression
Advise patients that ASMANEX HFA may cause systemic corticosteroid effects of hypercorticism
and adrenal suppression. Additionally, instruct patients that deaths due to adrenal insufficiency have
occurred during and after transfer from systemic corticosteroids. Patients should taper slowly from
systemic corticosteroids if transferring to ASMANEX HFA [see Warnings and Precautions (5.4 and 5.5)].
Reduction in Bone Mineral Density
Advise patients who are at an increased risk for decreased BMD that the use of corticosteroids may
pose an additional risk and should be monitored and, where appropriate, be treated for this condition [see
Warnings and Precautions (5.9)].
Reduced Growth Velocity
Inform patients that orally inhaled corticosteroids, including ASMANEX HFA, may cause a reduction
in growth velocity when administered to pediatric patients. Physicians should closely follow the growth of
pediatric patients taking corticosteroids by any route [see Warnings and Precautions (5.10)].
Glaucoma and Cataracts
Advise patients that long-term use of inhaled corticosteroids may increase the risk of some eye
problems (glaucoma or cataracts); regular eye examinations should be considered [see Warnings and
Precautions (5.11)].
Hypersensitivity Reactions Including Anaphylaxis
Advise patients that hypersensitivity reactions, such as urticaria, flushing, allergic dermatitis,
bronchospasm, rash, pruritus, angioedema, and anaphylactic reaction, may occur after administration of
ASMANEX HFA. Instruct patients to discontinue ASMANEX HFA if such reactions occur [see Warnings
and Precautions (5.8)].
Use Daily for Best Effect
Advise patients to use ASMANEX HFA at regular intervals, since its effectiveness depends on
regular use. Maximum benefit may not be achieved for 1 week or longer after starting treatment. If
symptoms do not improve after 2 weeks of therapy or if the condition worsens, instruct patients to contact
their physician.
Instructions for Use
Instruct patients regarding the following:
 Read the Patient Information before use and follow the Instructions for Use carefully.
 Remind patients to:
o  Remove the cap from the mouthpiece of the actuator before use.
o  Not remove the canister from the actuator.
o  Not wash inhaler in water. The mouthpiece should be cleaned using a dry wipe after
every 7 days of use.

How should I use ASMANEX HFA?
Read the step-by-step instructions for using ASMANEX HFA in the Instructions for Use.
 Use ASMANEX HFA exactly as prescribed. Do not use ASMANEX HFA more often than prescribed.
 You must use ASMANEX HFA regularly. It may take 1 week or longer after you start using ASMANEX HFA for your
asthma symptoms to get better. Do not stop using ASMANEX HFA even if you are feeling better, unless your healthcare
provider tells you to.
 Do not change or stop using ASMANEX HFA or other asthma medicines used to control or treat your breathing
problems unless told to do so by your healthcare provider. Your healthcare provider will change your medicines as
needed.
 ASMANEX HFA comes in 2 strengths. Your healthcare provider has prescribed the strength that is best for you. Pay
attention to the differences between ASMANEX HFA and your other inhaled medicines, including their prescribed use
and the way they look.
 Take ASMANEX HFA every day, with 2 puffs in the morning and 2 puffs in the evening.
 If you miss a dose of ASMANEX HFA, skip your missed dose and take your next dose at your regular time. Do not take
ASMANEX HFA more often or use more puffs than you have been prescribed.
 If you take more ASMANEX HFA than your healthcare provider has prescribed, call your healthcare provider right away.
 ASMANEX HFA does not relieve sudden asthma symptoms. Always have a rescue inhaler with you to treat sudden
symptoms. Use your rescue inhaler if you have breathing problems between doses of ASMANEX HFA. If you do not
have a rescue inhaler, call your healthcare provider to have a rescue inhaler prescribed for you.
 Do not use the ASMANEX HFA canister or actuator with any other medicines. Do not use any other medicine canister
or actuator with ASMANEX HFA.
 Rinse your mouth with water after each dose (2 puffs) of ASMANEX HFA. This will help to lessen the chance of getting
a yeast infection (thrush) in your mouth and throat.

 Instructions for Use
ASMANEX® HFA
(mometasone furoate)
Inhalation Aerosol
Read these Instructions for Use before you start using ASMANEX HFA and each time you get a refill.
There may be new information. This leaflet does not take the place of talking to your healthcare provider
about your medical condition or your treatment.
The parts of your ASMANEX HFA:
There are 2 main parts to your ASMANEX HFA inhaler: the metal canister that holds the medicine and
the blue plastic actuator that sprays the medicine from the canister.
 The inhaler also has a pink cap that covers the mouthpiece of the actuator (see Figure 1). The
cap from the mouthpiece must be removed before use. The inhaler contains “120” actuations
(puffs).

Figure 1
 

The inhaler comes with a dose counter located on the plastic actuator (see Figure 1). The
counter display will show the number of actuations (puffs) of medicine remaining. The first time
you use ASMANEX HFA the dose counter will show “124” actuations remaining. Each time you
press the canister, a puff of medicine is released and the counter will count down by 1. The
counter will stop counting at 0.

Important Information:
 Use ASMANEX HFA exactly as your healthcare provider tells you to.
 Remove the cap from the mouthpiece of the actuator before using ASMANEX HFA.
 Do not remove the canister from the actuator because:
o  you may not receive the correct amount of medication.
o  the dose counter may not function properly.
o  if you try to insert the canister back into the actuator this may cause the dose counter to
count down by 1 and may discharge a puff.
 

Use the ASMANEX HFA canister only with the actuator supplied with the product. Do not use
parts of the ASMANEX HFA inhaler with parts from any other inhalation medicine.

Before using your ASMANEX HFA:
Remove the cap from the mouthpiece of the actuator before using ASMANEX HFA (see Figure 2).
Check the mouthpiece for objects before use. Make sure the canister is fully inserted into the actuator.

 Figure 2
Priming your ASMANEX HFA Inhaler:
Before you use ASMANEX HFA for the first time, you must prime the inhaler.
1.   To prime the inhaler, hold it in the upright position away from your face, and press down firmly
and fully on the top of the canister until it stops moving in the actuator. Do this 4 times to release
a total of 4 actuations (puffs) into the air.
2.   Shake the inhaler well before each of the priming actuations. After priming 4 times, the dose
counter should read “120”.
3.   If you do not use your ASMANEX HFA for more than 5 days, you will need to prime it again
before use.
Using your ASMANEX HFA:
4.   Remove the cap from the mouthpiece of the actuator (see Figure 3). Check the mouthpiece
for objects before use. Make sure the canister is fully inserted into the actuator.
5.   Shake the inhaler well before each use.
6.   Breathe out as fully as you comfortably can through your mouth. Push out as much air from your
lungs as possible. Hold the inhaler in the upright position and place the mouthpiece into your
mouth (see Figure 4). Close your lips around the mouthpiece.

Figure 3

7.   Take a deep breath (inhale) in slowly through your mouth. While doing this, press down firmly and
fully on the top of the canister until it stops moving in the actuator. Take your finger off the
canister.

 8.   When you have finished breathing in, hold your breath as long as you comfortably can, up to 10
seconds. Then remove the inhaler from your mouth and breathe out through your nose, while
keeping your lips closed.
9.   Wait at least 30 seconds to take your second puff of ASMANEX HFA.
10. Shake the inhaler well again and repeat steps 6 through 8 to take your second puff of ASMANEX
HFA.
After using your ASMANEX HFA inhaler:
11. Replace the cap over the mouthpiece right away after use (see Figure 5).

Figure 5
12. After you finish taking ASMANEX HFA (2 puffs), rinse your mouth with water.
Reading the counter:
 

The dose counter identifies the number of inhalations (puffs) left in your inhaler (see Figure 6).

 

The counter will count down each time you release a puff of medicine (either when preparing your
ASMANEX HFA inhaler for use or when using the medicine).

Figure 6
When to replace your ASMANEX HFA:
 

It is important that you pay attention to the number of inhalations (puffs) left in your ASMANEX
HFA inhaler by reading the counter.

  

When the counter reads “20”, you should refill your prescription or ask your healthcare provider if
you need a new prescription for ASMANEX HFA.

 

Throw away ASMANEX HFA after the counter reaches “0”, indicating that you have used the
number of actuations on the product label and box. Your inhaler may not feel empty and it may
continue to operate, but you will not get the right amount of medicine if you keep using it.

 

Never try to change the numbers on the counter or remove the counter from the actuator.

 

Do not use the inhaler after the expiration date.

How to clean your ASMANEX HFA:
The mouthpiece should be cleaned using a dry wipe after every 7 days of use.
Routine cleaning instructions:


Remove the cap off the mouthpiece. Wipe the inside and outside surfaces of the actuator
mouthpiece with a clean, dry, lint-free tissue or cloth. Do not wash or put any parts of your
inhaler in water. Put the cap back on the mouthpiece after cleaning. 




Do not remove the canister from the actuator. 




Do not attempt to unblock the actuator with a sharp object, such as a pin.
