In short

What the research says.

A quick, data-only summary. The full evidence, dosing, and sources are below.

Sumatriptan is the prototypical triptan and the first serotonin 5-HT1B/1D receptor agonist developed specifically for the acute treatment of migraine attacks with or without aura. NutriStack rates the supporting evidence as strong. Common adult dosing is 50-100 mg oral; 6 mg subcutaneous; 5-20 mg intranasal; may repeat after 2 hours if needed, max 200 mg oral/day or 12 mg SC/day (as prescribed by your physician), though a prescriber sets the actual dose. This profile indexes 10 sources.

What it's good for
  • Rapid relief of migraine headache, nausea, and photophobia1,2
  • Subcutaneous injection provides relief within 10-15 minutes
  • Effective for cluster headache
  • Multiple delivery routes available
What to watch for
  • Tingling, warmth, and flushing (triptan sensations)
  • Chest tightness or pressure (usually non-cardiac)
  • Dizziness
  • Ischemic heart disease, coronary artery vasospasm (Prinzmetal's angina), or uncontrolled hypertension
  • History of stroke or TIA

The bottom line

Evidence rating strong. Most-documented uses: rapid relief of migraine headache, nausea, and photophobia, subcutaneous injection provides relief within 10-15 minutes, effective for cluster headache. 10 sources indexed (1994–2021), with 0 interaction records on file.

The science

How it works, mechanistically.

Core mechanism

Selectively activates serotonin 5-HT1B receptors on intracranial blood vessels, causing vasoconstriction of dilated meningeal and cerebral arteries. Also activates 5-HT1D receptors on trigeminal nerve terminals, inhibiting release of pro-inflammatory neuropeptides (CGRP, substance P) and blocking pain signal transmission through the trigeminovascular system.6

Class
Triptan / Antimigraine
Dosing

Dosing & protocol.

Common range
50-100 mg oral; 6 mg subcutaneous; 5-20 mg intranasal; may repeat after 2 hours if needed, max 200 mg oral/day or 12 mg SC/day (as prescribed by your physician)
Recommended form
Oral tablets for mild-moderate attacks; subcutaneous injection (6 mg) for severe attacks or when nausea prevents oral dosing

Oral bioavailability ~15% due to first-pass metabolism and incomplete absorption; subcutaneous bioavailability 97%. Migraine-related gastroparesis may further delay oral absorption.
