For oral inhalation only Treatment or prevention of bronchospasm in adults and children 4 years of age and older: 2 inhalations every 4 to 6 hours. In some patients, one inhalation every 4 hours may be sufficient. ( 2.1 ) Prevention of exercise-induced bronchospasm in adults and children 4 years of age and older: 2 inhalations 15 to 30 minutes before exercise. ( 2.2 ) Priming information: Prime Albuterol Sulfate HFA before using for the first time, or when the inhaler has not been used for more than 2 weeks. To prime Albuterol Sulfate HFA, release 3 sprays into the air away from the face. Shake well before each spray. ( 2.3 ) Cleaning information: At least once a week, wash the actuator with warm water, shake off excess, and air dry thoroughly. ( 2.3 ) Albuterol Sulfate HFA inhaler should be discarded when the dose counter displays 0 or after the expiration date on the product, whichever comes first. ( 2.3 ) 2.1 Bronchospasm For treatment of acute episodes of bronchospasm or prevention of symptoms associated with bronchospasm, the usual dosage for adults and children 4 years and older is two inhalations repeated every 4 to 6 hours. More frequent administration or a larger number of inhalations is not recommended. In some patients, one inhalation every 4 hours may be sufficient. 2.2 Exercise-Induced Bronchospasm The usual dosage for adults and children 4 years of age or older…

Use of Albuterol Sulfate HFA may be associated with the following: Paradoxical bronchospasm [see Warnings and Precautions (5.1) ] Cardiovascular effects [see Warnings and Precautions (5.4) ] Immediate hypersensitivity reactions [see Warnings and Precautions (5.6) ] Hypokalemia [see Warnings and Precautions (5.8) ] Most common adverse reactions (≥3.0% and >placebo) are headache, tachycardia, pain, dizziness, pharyngitis, and rhinitis. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Teva Pharmaceuticals at 1-888-483-8279 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience A total of 1090 subjects were treated with Albuterol Sulfate HFA Inhalation Aerosol, or with the same formulation of albuterol as in Albuterol Sulfate HFA Inhalation Aerosol, during the worldwide clinical development program. 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. Adult and Adolescents 12 Years of Age and Older: The adverse reaction information presented in the table below concerning Albuterol Sulfate HFA Inhalation Aerosol is derived from a 6-week, blinded study which compared Albuterol Sulfate HFA Inhalation Aerosol (180 mcg four times daily) with a…

Albuterol Sulfate HFA Inhalation Aerosol is contraindicated in patients with a history of hypersensitivity to albuterol and any other Albuterol Sulfate HFA Inhalation Aerosol components. Rare cases of hypersensitivity reactions, including urticaria, angioedema, and rash have been reported after the use of albuterol sulfate [see Warnings and Precautions (5.6) ] . Hypersensitivity to albuterol and any other Albuterol Sulfate HFA Inhalation Aerosol Components. ( 4 )

The expected symptoms with overdosage are those of excessive beta-adrenergic stimulation and/or occurrence or exaggeration of any of the symptoms listed under ADVERSE REACTIONS, e.g., seizures, angina, hypertension or hypotension, tachycardia with rates up to 200 beats per minute, arrhythmias, nervousness, headache, tremor, dry mouth, palpitation, nausea, dizziness, fatigue, malaise, and insomnia. Hypokalemia may also occur. As with all sympathomimetic medications, cardiac arrest and even death may be associated with abuse of Albuterol Sulfate HFA Inhalation Aerosol. Treatment consists of discontinuation of Albuterol Sulfate HFA Inhalation Aerosol together with appropriate symptomatic therapy. The judicious use of a cardioselective beta-receptor blocker may be considered, bearing in mind that such medication can produce bronchospasm. There is insufficient evidence to determine if dialysis is beneficial for overdosage of Albuterol Sulfate HFA Inhalation Aerosol. The oral median lethal dose of albuterol sulfate in mice is greater than 2,000 mg/kg (approximately 6,800 times the maximum recommended daily inhalation dose for adults on a mg/m 2 basis and approximately 3,200 times the maximum recommended daily inhalation dose for children on a mg/m 2 basis). In mature rats, the subcutaneous median lethal dose of albuterol sulfate is approximately 450 mg/kg (approximately 3,000 times…

Other short-acting sympathomimetic aerosol bronchodilators should not be used concomitantly with Albuterol Sulfate HFA Inhalation Aerosol. If additional adrenergic drugs are to be administered by any route, they should be used with caution to avoid deleterious cardiovascular effects. Other short-acting sympathomimetic aerosol bronchodilators and adrenergic drugs: May potentiate effect. ( 7 ) Beta-blockers: May decrease effectiveness of Albuterol Sulfate HFA and produce severe bronchospasm. Patients with asthma should not normally be treated with beta-blockers. ( 7.1 ) Diuretics, or non-potassium sparing diuretics: May potentiate hypokalemia or ECG changes. Consider monitoring potassium levels. ( 7.2 ) Digoxin: May decrease serum digoxin levels. Consider monitoring digoxin levels. ( 7.3 ) Monoamine oxidase (MAO) inhibitors and tricyclic antidepressants: May potentiate effect of albuterol on the cardiovascular system. Consider alternative therapy in patients taking MAOs or tricyclic antidepressants. ( 7.4 ) 7.1 Beta-Blockers Beta-adrenergic-receptor blocking agents not only block the pulmonary effect of beta-agonists, such as Albuterol Sulfate HFA Inhalation Aerosol, but may produce severe bronchospasm in asthmatic patients. Therefore, patients with asthma should not normally be treated with beta-blockers. However, under certain circumstances, e.g., as prophylaxis after myocardial infarction, there may be no acceptable alternatives to the use of beta-adrenergic-blocking agents in patients with asthma. In this setting, consider cardioselective beta-blockers, although they should be administered with caution. 7.2 Diuretics The ECG changes and/or hypokalemia which may result from the administration of non-potassium sparing diuretics (such as loop or thiazide diuretics) can be acutely worsened by beta-agonists, especially when the recommended dose of the beta-agonist is exceeded. Although the clinical significance of these effects is not known, caution is advised in the coadministration of beta-agonists with non-potassium sparing diuretics. Consider monitoring potassium levels. 7.3 Digoxin Mean decreases of 16% and 22% in serum digoxin levels were demonstrated after single dose intravenous and oral administration of albuterol, respectively, to normal volunteers who had received digoxin for 10 days. The clinical significance of these findings for patients with obstructive airway disease who are receiving albuterol and digoxin on a chronic basis is unclear. Nevertheless, it would be prudent to carefully evaluate the serum digoxin levels in patients who are currently receiving digoxin and Albuterol Sulfate HFA Inhalation Aerosol. 7.4 Monoamine Oxidase Inhibitors or Tricyclic Antidepressants Albuterol Sulfate HFA Inhalation Aerosol should be administered with extreme caution to patients being treated with monoamine oxidase inhibitors or tricyclic antidepressants, or within 2 weeks of discontinuation of such agents, because the action of albuterol on the cardiovascular system may be potentiated. Consider alternative therapy in patients taking MAO inhibitors or tricyclic antidepressants.
