Asthma: Isivas should be taken once daily in the evening (one-10 mg tablet).
Exercise-Induced Bronchoconstriction (EIB): For prevention of EIB, a single dose (one-10 mg tablet) of Isivas should be taken at least 2 hours before exercise.
An additional dose of Isivas should not be taken within 24 hours of previous dose. Patients already taking Isivas daily for another indication (including chronic asthma) should not take an additional dose to prevent EIB. All patients should have available for rescue a short-acting β-agonist.
