What is montelukast used for?
Montelukast is a prescription medicine used to help prevent and treat certain asthma and allergy-related symptoms by blocking a specific inflammation pathway in the body.[1]
It is commonly prescribed for:
- Asthma: to prevent symptoms and help reduce asthma flare-ups in people who meet the prescribing criteria.[1]
- Allergies (especially allergic rhinitis): to relieve symptoms like congestion/runny nose and sneezing.[1]
How does montelukast work?
Montelukast is a leukotriene receptor antagonist. It blocks leukotrienes, chemicals involved in allergic inflammation and airway narrowing. By blocking them, montelukast can reduce inflammation-related symptoms in asthma and allergic conditions.[1]
What are common side effects people report?
Side effects can vary by person. Commonly reported effects include sleep-related changes and other general effects seen with many asthma/allergy medicines.[1]
Because montelukast has specific safety considerations (including rare but serious neuropsychiatric effects), clinicians often discuss risks before prescribing and monitor patients during treatment.[1]
What is the safety concern patients ask about most?
The main patient-facing concern with montelukast is the potential for serious neuropsychiatric side effects. These can include behavioral and mood changes, and in rare cases more severe effects. Patients are typically advised to contact a clinician promptly if such symptoms occur.[1]
Does montelukast come as a brand or generic?
Montelukast is available as a generic medicine (montelukast sodium). Brand names have varied over time by country, but the active ingredient is the same.[1]
