- Asthma: provides maintenance therapy to reduce frequency and severity of symptoms. - Allergic rhinitis: alleviates nasal congestion, sneezing and itching. - Exercise‑induced bronchoconstriction: prevents airway narrowing during physical activity.

Montelukast is generally well tolerated, but adverse reactions can occur.

Common Side Effects: - Headache: mild to moderate intensity. - Abdominal pain: occasional discomfort. - Cough: transient irritation. - Nausea: mild upset stomach.

Serious or Rare Side Effects: - Angioedema: swelling of face, lips or throat. - Eosinophilic granulomatosis with polyangiitis: rare vasculitic syndrome. - Severe rash or Stevens‑Johnson syndrome. - Mood changes or suicidal thoughts. - Hepatic injury: elevated liver enzymes. - Anaphylaxis: immediate hypersensitivity reaction.

Before prescribing Monkasta, clinicians should consider several safety aspects.

- Assess liver function: monitor transaminases in patients with hepatic disease. - Review psychiatric history: observe for mood changes or suicidal ideation. - Avoid use in patients with known hypersensitivity to montelukast or any tablet excipients. - Consider dose adjustment in severe renal impairment: follow prescriber guidance. - Store at room temperature: keep in the original pack, protect from moisture and light.

Montelukast may interact with other medicines, requiring attention to potential changes in efficacy or safety.

Major Interactions (Avoid): - Ritonavir: can increase montelukast plasma concentrations. - Phenobarbital: may reduce montelukast effectiveness. - Carbamazepine: may lower montelukast levels.

Moderate Interactions (Monitor Closely): - Fluconazole: may raise montelukast concentrations. - Warfarin: monitor INR as interaction is possible. - Theophylline: watch for additive bronchospasm risk.
