warnings and cautions
5 WARNINGS AND PRECAUTIONS Life-threatening paradoxical bronchospasm may occur. Discontinue levalbuterol inhalation solution immediately and treat with alternative therapy. ( 5.1 ) Need for more doses of levalbuterol inhalation solution than usual may be a sign of deterioration of asthma and requires reevaluation of treatment. ( 5.2 ) Levalbuterol inhalation solution is not a substitute for corticosteroids. ( 5.3 ) Cardiovascular effects may occur. Consider discontinuation of levalbuterol inhalation solution if these effects occur. Use with caution in patients with underlying cardiovascular disorders. ( 5.4 ) Excessive use may be fatal. Do not exceed recommended dose. ( 5.5 ) Immediate hypersensitivity reactions may occur. Discontinue levalbuterol inhalation solution immediately. ( 5.6 ) Hypokalemia and changes in blood glucose may occur. ( 5.7 , 5.8 ) 5.1 Paradoxical Bronchospasm Levalbuterol inhalation solution can produce paradoxical bronchospasm, which may be life-threatening. If paradoxical bronchospasm occurs, levalbuterol 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. 5.2 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 levalbuterol inhalation solution than usual, this may be a marker of destabilization of asthma and requires reevaluation of the patient and treatment regimen, giving special consideration to the possible need for anti-inflammatory treatment, e.g., corticosteroids. 5.3 Use of Anti-Inflammatory Agents Levalbuterol inhalation solution is not a substitute for corticosteroids. The use of beta-adrenergic agonists alone may not be adequate to control asthma in many patients. Early consideration should be given to adding anti-inflammatory agents, e.g., corticosteroids, to the therapeutic regimen. 5.4 Cardiovascular Effects Levalbuterol inhalation solution, like other beta-adrenergic agonists, can produce clinically significant cardiovascular effects in some patients, as measured by heart rate, blood pressure, and symptoms. Although such effects are uncommon after administration of levalbuterol inhalation solution at recommended doses, if they o...

Adults and Adolescents 12 Years of Age and Older Adverse reaction information concerning levalbuterol inhalation solution in adults and adolescents is derived from one 4 week, multicenter, randomized, double-blind, active-, and placebo-controlled trial in 362 patients with asthma 12 years of age and older. Adverse reactions reported in ≥ 2% of patients receiving levalbuterol inhalation solution or racemic albuterol and more frequently than in patients receiving placebo are listed in Table 1.
