WARNINGS DETERIORATION OF ASTHMA Asthma may deteriorate acutely over a period of hours or chronically over several days or longer. If the patient needs more doses of albuterol inhalation solution than usual, this may be a marker of destabilization of asthma and requires re-evaluation of the patient and treatment regimen, giving special consideration to the possible need for anti-inflammatory treatment, e.g., corticosteroids. USE OF ANTI-INFLAMMATORY AGENTS The use of beta-adrenergic agonist bronchodilators alone may not be adequate to control asthma in many patients. Early consideration should be given to adding anti-inflammatory agents, e.g., corticosteroids. PARADOXICAL BRONCHOSPASM Albuterol inhalation solution can produce paradoxical bronchospasm, which may be life threatening. If paradoxical bronchospasm occurs, albuterol inhalation solution should be discontinued immediately and alternative therapy instituted. It should be recognized that paradoxical bronchospasm, when associated with inhaled formulations, frequently occurs with the first use of a new vial. CARDIOVASCULAR EFFECTS Albuterol inhalation solution, like all other beta-adrenergic agonists, can produce a clinically significant cardiovascular effect in some patients as measured by pulse rate, blood pressure, and/or symptoms. Although such effects are uncommon after administration of albuterol inhalation solution at recommended doses, if they occur, the drug may need to be discontinued. In addition, beta-agonists have been reported to produce electrocardiogram (ECG) changes, such as flattening of the T wave, prolongation of the QTc interval, and ST segment depression. The clinical significance of these findings is unknown. Therefore, albuterol inhalation solution, like all sympathomimetic amines, should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension. IMMEDIATE HYPERSENSITIVITY REACTIONS Immediate hypersensitivity reactions may occur after administration of albuterol, as demonstrated by rare cases of urticaria, angioedema, rash, bronchospasm, anaphylaxis, and oropharyngeal edema.
ADVERSE REACTIONS The results of clinical trials with albuterol inhalation solution in 135 patients showed the following side effects which were considered probably or possibly drug related: Percent Incidence of Adverse Reactions Reaction Percent Incidence (N=135) Central Nervous System Tremors 20 Dizziness 7 Nervousness 4 Headache 3 Insomnia 1 Gastrointestinal Nausea 4 Dyspepsia 1 Ear, nose and throat Nasal congestion 1 Pharyngitis <1 Cardiovascular Tachycardia 1 Hypertensions 1 Respiratory Bronchospasm 8 Cough 4 Bronchitis 4 Wheezing 1 No clinically relevant laboratory abnormalities related to albuterol inhalation solution were determined in these studies. Cases of urticaria, angioedema, rash, bronchospasm, hoarseness, oropharyngeal edema, and arrhythmias (including atrial fibrillation, supraventricular tachycardia, and extrasystoles) have also been reported after the use of inhaled albuterol.
