Rizatriptan, sold under the brand name Maxalt among others, is a medication used for the treatment of migraine headaches.[1][3] It is taken by mouth.[1][3] It can also be applied on the tongue.[2] It is a serotonin (5-HT) 1B/1D receptor agonist (triptan).[1][2]

Common side effects include chest pain, dizziness, dry mouth, and tingling.[3] Other side effects may include myocardial infarction, stroke, high blood pressure, serotonin syndrome, and anaphylaxis.[3] Excessive use may result in medication overuse headaches.[3] Use is not recommended during pregnancy and breastfeeding is not recommended within 24 hours after taking a dose.[4] Rizatriptan is in the triptan class and is believed to work by activating the 5-HT1 receptor.[3]

Rizatriptan was patented in 1991 and came into medical use in 1998.[5][6] It is available as a generic medication.[4] In 2020, it was the 134th most commonly prescribed medication in the United States, with more than 4 million prescriptions.[7][8]

Medical uses

Rizatriptan is indicated to treat acute migraine attacks with or without aura.[1][2] It does not prevent future migraine attacks.[9] A 2010 review found rizatriptan to be more efficacious and tolerable than sumatriptan.[10]

Contraindications

Rizatriptan and other triptans can cause vasoconstriction, they are contraindicated in people with cardiovascular conditions.[11]

Adverse effects

Frequent adverse effects (incidence less than 10%) are dizziness, drowsiness, asthenia/fatigue, and nausea. Clinical adverse experiences were typically mild and short-lasting (2–3 hours).[11]

Interactions

Mechanism of action

Rizatriptan acts as an agonist at serotonin 5-HT1B and 5-HT1D receptors.[13] Like the other triptans sumatriptan and zolmitriptan, rizatriptan induces vasoconstriction—possibly by inhibiting the release of calcitonin gene-related peptide from sensory neurons in the trigeminal nerve.[13]
