Frovatriptan succinate is used to treat migraine headaches. It works by binding to serotonin receptors in the brain and blood vessels to relieve pain and inhibit dilation of blood vessels. Common side effects include dizziness, fatigue, nausea, and chest pain. It should be used cautiously in patients with risk factors for heart disease due to potential cardiovascular side effects like arrhythmias and myocardial ischemia. The recommended dosage is 2.5 mg taken orally as needed for migraine symptoms.
