Relpax

Relpax is a prescription drug used to treat migraines once they start. A migraine headache can result when some of the blood vessels in the head become dilated. Relpax works by narrowing these blood vessels, returning them to their normal state. The medication comes in a tablet form that should be taken by mouth as soon as a migraine starts. As with any medication, there are potential side effects that may occur with Relpax, such as nausea, dizziness, and drowsiness.

 

What Is Relpax?

Relpax® (eletriptan hydrobromide) is a prescription medication that is used to treat migraine headaches. Relpax will not help to prevent migraines, but it can help to treat a migraine that has already started.

How Does Relpax Work?

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.
 

Relpax Effects

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 Relpax.
