Montelukast is a leukotriene receptor antagonist. It blocks cysteinyl leukotriene (CysLT1) receptors in the airways and nasal mucosa, reducing inflammation, bronchoconstriction, mucus production and allergy symptoms.

Chew the tablet completely before swallowing. Usually taken once daily as prescribed; for asthma, commonly in the evening. Can be taken with or without food. Not for sudden asthma attacks—use a rescue inhaler if prescribed.

Headache, abdominal pain, diarrhea, nausea, fever, cough, sore throat, tiredness

Use with caution in hepatic impairment. Phenylketonuria (PKU): check label for aspartame/phenylalanine content if applicable.
