Two montelukast products sit on this shelf: Singulair, spanning 4 mg to 10 mg, and Montair at 10 mg. Both are tablets listed for Asthma, Allergic Rhinitis and exercise-induced bronchoconstriction.
Key points
- Montelukast carries a boxed warning for serious neuropsychiatric events: agitation, aggression, depression, sleep disturbance and suicidal thoughts have all been reported. The label advises stopping the medicine and contacting a healthcare provider if these occur.
- Montelukast is a leukotriene receptor antagonist. It blocks inflammatory chemicals called leukotrienes that narrow the airways, increase mucus and draw immune cells into lung tissue.
- Singulair is the original brand from Merck; Montair is Cipla’s generic version. Both contain montelukast sodium and share the same indications.
