Generic availability

- The drug is available as a generic sumatriptan in the same dosage forms (25 mg, 50 mg, 100 mg tablets, 50 mg nasal spray, 50 mg injectable).
- The generic is typically priced lower than the brand versions, but the active ingredient and pharmacology are identical.

Key points

- Indication: acute treatment of migraine headaches (with or without aura).
- Mechanism: selective serotonin (5‑HT1B/1D) receptor agonist that constricts cranial blood vessels and inhibits pain‑related neuropeptide release.
- Administration: take a 25–50 mg tablet as soon as migraine symptoms appear; a second dose can be taken after 2 hours if needed, but do not exceed 100 mg in a 24‑hour period.
