Efficacy Monitoring Parameters. Inhalation technique, resolution of asthma symptoms, and pulmonary function tests.

Toxicity Monitoring Parameters. Use alternative therapy or seek emergency treatment if paradoxical bronchospams occur.

Key Patient Counseling Points. Instruct patient on inhaler technique. Wash the mouthpiece and air dry thoroughly at least once a week (may cease to deliver medication if mouthpiece becomes blocked). Do not crush extended-release tablets. Part of the extended-release tablet may pass into stool. Contact prescriber if more albuterol is needed to control symptoms than usual as this may indicate asthma deterioration.

Clinical Pearls. The National Heart, Lung and Blood Institute asthma guidelines recommend short-acting beta-agonists (SABA) as the drug of choice for treating acute asthma symptoms and exacerbations. Do not use SABA as a component of chronic therapy without an anti-inflammatory agent.
