Rizatriptan is used for the treatment of acute migraine headaches. It alleviates the symptoms of migraines and helps prevent the attack from worsening.
How Rizatriptan Works Migraine headaches are believed to result from the dilation of blood vessels in the head. Rizatriptan works by constricting these blood vessels, thereby alleviating migraine headaches.
Common side effects of Rizatriptan include flushing (a sense of warmth in the face, ears, neck, and trunk), diarrhea, insomnia (difficulty sleeping), vomiting, palpitations, mental impairment, euphoria (a feeling of intense excitement and happiness), tremors, shortness of breath, tachycardia, cold extremities, muscle pain, vertigo, itching, hearing loss, and hallucinations.
