Prescription ·Exploratory record · not publication-reviewed ·Updated July 13, 2026

Rizatriptan is a second-generation triptan for the acute treatment of migraine with or without aura. It has faster onset and higher consistency of response compared to sumatriptan in some studies. The orally disintegrating tablet (MLT) formulation is convenient for patients with migraine-associated nausea who have difficulty swallowing.

In short

What the research says.

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

Rizatriptan is a second-generation triptan for the acute treatment of migraine with or without aura. NutriStack rates the supporting evidence as strong. Common adult dosing is 5-10 mg at migraine onset; may repeat after 2 hours if needed, max 30 mg/day. Use 5 mg dose if taking propranolol (as prescribed by your physician), though a prescriber sets the actual dose. This profile indexes 10 sources.

What it's good for
  • Rapid onset of action (as early as 30 minutes)
  • Orally disintegrating tablet for ease of use during migraine
  • High rate of 2-hour headache relief1,4
  • Effective for migraine-associated nausea and photophobia2,4
What to watch for
  • Dizziness
  • Somnolence and fatigue
  • Chest tightness or pressure
  • Ischemic coronary artery disease or coronary vasospasm
  • Uncontrolled hypertension

The bottom line

Evidence rating strong. Most-documented uses: rapid onset of action (as early as 30 minutes), orally disintegrating tablet for ease of use during migraine, high rate of 2-hour headache relief. 10 sources indexed (1998–2006), with 0 interaction records on file.

The science

How it works, mechanistically.

Core mechanism

Selectively binds to serotonin 5-HT1B and 5-HT1D receptors. At 5-HT1B receptors on cranial blood vessels, it causes selective vasoconstriction. At 5-HT1D receptors on trigeminal sensory nerve endings, it inhibits release of vasoactive neuropeptides (CGRP, substance P) and reduces transmission of pain signals through the trigeminal nucleus caudalis.8
