Imitrex, a triptan medication, is used for the acute management of migraine and related headache disorders.

Migraine: provides rapid relief of migraine pain, nausea, and sensitivity to light or sound. Cluster headache: may be employed for acute relief of cluster headache episodes when prescribed.

Common Side Effects: - Taste disturbance or bitter taste - Nasal irritation or burning sensation - Dizziness or light‑headedness - Drowsiness or fatigue - Nausea or mild stomach upset - Flushing or warmth sensation

Serious or Rare Side Effects: - Chest pain or coronary vasospasm - Severe hypertension or hypertensive crisis - Serotonin syndrome, especially with serotonergic drugs - Allergic reactions including rash or angioedema - Myocardial infarction or cardiac arrhythmia - Anaphylaxis or severe hypersensitivity

Before using Imitrex, consider the following precautions: - Cardiovascular disease: avoid if you have coronary artery disease, uncontrolled hypertension, or a history of myocardial infarction. - Hemiplegic or basilar migraine: contraindicated in these migraine subtypes. - Concomitant serotonergic agents: use with caution when combined with SSRIs, SNRIs, or MAO inhibitors. - Pregnancy and lactation: only if the potential benefit outweighs the risk; consult your healthcare provider. - Age restrictions: not recommended for children or adolescents under 18 years. - Store at room temperature: keep in the original packaging, protect from moisture and direct heat.

Sumatriptan may interact with several medication classes.

Major Interactions (Avoid): - MAO inhibitors: increased risk of serotonin syndrome. - Other triptans or ergot alkaloids: additive vasoconstrictive effects. - SSRIs, SNRIs, or other serotonergic agents: heightened serotonin toxicity. - Certain antihypertensives: may potentiate blood pressure changes.

Moderate Interactions (Monitor Closely): - CYP3A4 inhibitors (e.g., ketoconazole, erythromycin): may raise sumatriptan levels. - CYP3A4 inducers (e.g., rifampin, carbamazepine): may reduce efficacy. - Oral contraceptives: monitor for increased migraine frequency.
