    Frovatriptan, sold under the brand name Frova among others, is a medication used to treat migraine headaches.[1] It may also be used to prevent menstrual migraine.[2] It is taken by mouth.[2]

    Common side effects include tiredness, numberness, flushing, dry mouth, pain, heart burn, and trouble sleeping.[1] Other side effects may include serotonin syndrome, high blood pressure, heart attack, and medication overuse headaches.[1] Safety in pregnancy is unclear, and use within 24 hours of breastfeeding is not recommended.[3] It is a triptan.[1]

    was approved for medical use in the United States in 2001.[1] It is available as a generic medication. In the United Kingdom 6 pills of 2.5 mg costs the NHS about £6 as of 2021.[2] This amount in the United States costs about 67 USD.[4]

    Frovatriptan is used in the treatment of migraine.[5] It may also be used for short term prevention of menstrual migraine.[6]

    It is available as 2.5 mg tablets. One is recommended as soon as the headache starts, with a maximum dose of 5 mg per day.[2]

    Pharmacology

    Pharmacodynamics

    Further information: Serotonin receptor agonist and Triptan § Mechanism_of_action

    Frovatriptan is a serotonin receptor agonist, with high affinity for the 5-HT1B/1D receptors. It has no significant effects on the GABAA mediated channel activity and benzodiazepine binding sites. Frovatriptan inhibits excessive dilation of arteries that supply blood to the head.

    Pharmacokinetics

    Frovatriptan has mean terminal elimination half-life of approximately 26 hours, which is substantially longer than other triptans.

    Society and culture

    The product is licensed to Endo Pharmaceuticals in North America and Menarini in Europe.[7]

    Licensing

    Frovatriptan is available only by prescription in the United States and Canada, where a secondary New Drug Approval (sNDA) was filed in July 2006.[8]
