It is made by Pfizer.
Relpax is part of a class of
migraine medications called 5-HT agonists (or more commonly known as "
triptans"). During a migraine
headache, some of the blood vessels in the head become dilated (wider than they usually are). Relpax works by narrowing these blood vessels, helping them return to their normal state. This action helps to relieve
migraine symptoms.
In studies, up to 77 percent of people with migraines had no (or mild) pain within two hours of taking Relpax, compared to only 19 to 39.5 percent of people who did not take it.
