What Is Rizatriptan?

Rizatriptan is a prescription migraine medication belonging to the serotonin 5-HT1B/1D receptor agonist class, commonly called triptans. It is used for the acute treatment of migraine with or without aura in adults and children aged six through 17 years. Rizatriptan is available as conventional oral tablets and orally disintegrating tablets, including products associated with Maxalt and Maxalt-MLT. It acts on migraine-related nerve and blood vessel pathways to relieve symptoms during an attack. Rizatriptan is not intended to prevent future migraines or treat every type of headache. Certain cardiovascular conditions and medication interactions make it unsuitable for some patients.

How Does Rizatriptan Work?

Rizatriptan activates serotonin 5-HT1B and 5-HT1D receptors involved in migraine signaling. Activation of these receptors can constrict selected cranial blood vessels and reduce the release of inflammatory neuropeptides from trigeminal nerve endings. These effects help interrupt pathways associated with migraine pain. Rizatriptan can relieve headache and associated symptoms such as sensitivity to light or sound during an acute migraine. It does not eliminate the underlying tendency to experience migraines and is not a preventive medication. Because it can constrict blood vessels, rizatriptan is contraindicated in patients with certain cardiovascular or cerebrovascular disorders.

What Type of Migraine Does Rizatriptan Treat?

Rizatriptan is approved for acute migraine attacks with or without aura in adults and pediatric patients aged six through 17 years. Migraine can cause moderate to severe headache, nausea, sensitivity to light or sound, and sometimes temporary visual or sensory disturbances. Rizatriptan should be used only when a clear migraine diagnosis has been established. It is not approved for migraine prevention or cluster headache treatment. Patients with coronary artery disease, previous stroke or transient ischemic attack, uncontrolled hypertension, or certain other vascular conditions should not use rizatriptan. A clinician evaluates cardiovascular risk and interacting medications before prescribing treatment.

How Should Rizatriptan Be Taken?

Adults generally take 5 mg or 10 mg orally when a migraine attack begins. If the headache returns after initial improvement, a second adult dose may be taken at least two hours later, with a maximum of 30 mg in 24 hours. Adults taking propranolol should receive only 5 mg per dose, with a maximum of 15 mg daily. Children aged six through 17 years receive a single weight-based dose of 5 mg if they weigh less than 40 kg or 10 mg if they weigh at least 40 kg. Repeat dosing within 24 hours has not been established for pediatric patients. Rizatriptan must not be taken within 24 hours of another triptan or ergot medication.

What Are the Side Effects and Warnings of Rizatriptan?

Common adverse effects include dizziness, sleepiness, fatigue, nausea, and sensations of pressure or tightness in the chest, throat, or neck. Serious risks include coronary artery spasm, heart attack, stroke, dangerous heart rhythm disturbances, and serotonin syndrome. Rizatriptan is contraindicated in patients with certain cardiovascular diseases, uncontrolled hypertension, or a history of stroke. Monoamine oxidase-A inhibitors and certain other migraine medications can cause important interactions. Frequent use of acute headache medications may contribute to medication-overuse headache. Severe chest pain, sudden weakness, difficulty speaking, or unusual neurological symptoms requires emergency care.

Common Questions About Rizatriptan

Is rizatriptan the same as Maxalt?

Yes. Maxalt and Maxalt-MLT are brand names for rizatriptan formulations used for acute migraine treatment.

Can rizatriptan prevent migraine attacks?

No. Rizatriptan is intended to treat an existing migraine attack, not prevent future migraines.

Can children take rizatriptan?

Yes. Rizatriptan is approved for acute migraine treatment in children aged six through 17 years, using weight-based dosing.

Can rizatriptan be taken with propranolol?

Yes, in eligible patients, but propranolol increases rizatriptan exposure. Adults taking propranolol should use only 5 mg per dose, up to 15 mg in 24 hours.
