Montelukast should be taken once daily. For asthma, the dose should be taken in the evening. For allergic rhinitis, the time of administration may be individualized to suit patient needs. Patients with both asthma and allergic rhinitis should take only one tablet daily in the evening.
Pediatric Patients 6 to 14 years of age with asthma and/or allergic rhinitis: One 5 mg chewable tablet daily. No dosage adjustment.
Pediatric Patients 2 to 5 years of age with asthma and/or allergic rhinitis: One 4 mg chewable tablet daily.
Exercise-induced Bronchoconstriction (EIB) in patients 15 years of age and older: For prevention of EIB, a single dose of Montelukast tablets should be taken at least 2 hours before exercise. An additional dose of Montelukast should not be taken within 24 hours of a previous dose. Patients already taking one tablet daily for another indication (including chronic asthma) should not take an additional dose to prevent EIB. A short-acting (beta)-agonist should be available for rescue of patients.
