Labeled uses (from FDA prescribing information)
Cromolyn sodium inhalation solution USP is a prophylactic agent indicated in the management of patients with bronchial asthma. In patients whose symptoms are sufficiently frequent to require a continuous program of medication, cromolyn sodium inhalation solution USP is given by inhalation on a regular daily basis (see DOSAGE AND ADMINISTRATION ). The effect of cromolyn sodium is usually evident after several weeks of treatment, although some patients show an almost immediate response. In patients who develop acute bronchoconstriction in response to exposure to exercise, toluene diisocyanate, environmental pollutants, etc., cromolyn sodium should be given shortly before exposure to the precipitating factor (see DOSAGE AND ADMINISTRATION ).
