What Experts Say

Montelukast is a leukotriene receptor antagonist. It blocks the action of leukotrienes, chemicals the body releases during allergic reactions and asthma attacks that cause airway swelling, mucus production, and tightening of the airway muscles.

Doctors in Pakistan prescribe Singulair as a maintenance therapy for asthma, not for treating a sudden attack, since it does not work fast enough for immediate relief. It is often used alongside inhaled steroids or as an alternative when inhalers are difficult to use correctly.

Parents and patients should watch for mood or behavior changes, since Montelukast has been linked in rare cases to sleep disturbances, agitation, or low mood, especially in children. Any new psychiatric symptoms after starting the medicine should be reported to a doctor promptly.
