Relpax is used to relieve the symptoms of a migraine after it starts. It is not designed to prevent a migraine from occurring. The medication works by helping the blood vessels in the head return to their normal state after dilating during a migraine. Some "off-label" Relpax uses involve the treatment of cluster headaches.
What Is Relpax Used For?Relpax® (eletriptan hydrobromide) is a prescription medication used to treat migraine headaches.
Using Relpax for MigrainesMigraine headaches are different from other headaches in many ways. Some of the most common migraine symptoms include:
- Headache pain on one side of the head
- Sensitivity to light or sound
- Throbbing headache pain
- Upset stomach (nausea) and vomiting
- Unusual vision changes.
Some people may have an aura before their migraines occur. An aura can be any unusual sign that a migraine is about to happen, including vision changes, numbness, tingling, or speech changes. The most common type of an aura is visual (seeing spots, tunnel vision, or other vision changes). Some people have migraine triggers, which are certain foods, drinks, or situations that seem to lead to a migraine (see Migraine Diet for more information).
Relpax is approved for migraines with or without an aura. 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 the symptoms of a migraine.
Due to the way it works, Relpax is not designed for migraine prevention. Relpax is taken to lessen the pain and other symptoms of a migraine once it starts.
