Imigran (sumatriptan) is indicated for acute migraine management, acting on the trigeminovascular pathway. - Acute migraine attack: provides rapid relief of headache and associated nausea. - Migraine with aura: alleviates pain and visual disturbances during an attack. - Cluster headache (acute): reduces severity of episodic cluster headache attacks.

Sumatriptan nasal spray may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects: - Taste disturbance: altered or unpleasant taste after administration. - Nasal irritation: burning, stinging, or discomfort in the nasal passages. - Dizziness: feeling light‑headed or unsteady. - Somnolence: mild sleepiness or fatigue. - Nausea: mild gastrointestinal upset. - Flushing: transient warmth or redness of the skin.

Serious or Rare Side Effects: - Chest pain: may indicate cardiac ischemia. - Coronary vasospasm: constriction of coronary arteries. - Severe hypertension: sudden increase in blood pressure. - Serotonin syndrome: agitation, hyperthermia, muscle rigidity. - Allergic reaction: rash, swelling, or difficulty breathing. - Ischemic events: stroke or transient ischemic attack.

When prescribing Imigran, clinicians should consider several safety precautions to minimize risk. - Cardiovascular disease: contraindicated in patients with known coronary artery disease or uncontrolled hypertension. - Hemiplegic or basilar migraine: avoid use due to increased stroke risk. - Serotonergic agents: caution when combined with SSRIs, SNRIs, or MAO inhibitors. - Liver impairment: use with caution in moderate hepatic dysfunction. - Pregnancy and lactation: safety not established; assess risk‑benefit before use. - Store at ambient temperature: keep below 25 °C in original packaging, protect from moisture and direct sunlight.

Sumatriptan can interact with other medicines, affecting its safety or efficacy.

Major Interactions (Avoid): - MAO inhibitors: risk of severe serotonin syndrome. - Other triptans: additive vasoconstrictive effects. - Ergot alkaloids: increased vasospasm risk. - SSRIs/SNRIs: potential for serotonin syndrome.

Moderate Interactions (Monitor Closely): - Antihypertensives: may enhance blood pressure lowering. - CYP3A4 inhibitors (e.g., ketoconazole): increase sumatriptan plasma levels. - CYP3A4 inducers (e.g., rifampin): reduce efficacy of sumatriptan. - Oral contraceptives: may alter hormonal migraine patterns.
