Relpax (Eletriptan) belongs to the class of medications known as 5-hydroxytryptamine receptor agonists. Relpax (Eletriptan) is used to treat migraine Headaches with or without aura (warning signs that occur before the migraine headache begins) in adults. It is not used to prevent migraine headaches or to treat any other type of migraine headache including hemiplegic (one side of the head only), ophthalmoplegic (affecting the eye area only), or basilar (at the bottom of the head only) migraine.
Migraine headaches are thought to be caused by the dilation (widening) of the blood vessels in the head. Relpax (Eletriptan) works by causing the blood vessels of the head to constrict. For most people, Relpax (Eletriptan) eliminates or reduces the symptoms of migraine attacks including headache, nausea, vomiting, and sensitivity to light and sound. Most people notice an effect within 2 hours after taking the medication.
Relpax (Eletriptan) may be available under multiple brand names and/or in several different forms. Any specific brand name of Relpax (Eletriptan) may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of Relpax (Eletriptan) may not be used for all of the conditions discussed here.
Your doctor may have suggested Relpax (Eletriptan) for conditions other than those listed in these drug information articles.

The recommended adult dose of Relpax (Eletriptan) is one 20 mg or 40 mg tablet taken at the first sign of a migraine headache. If your headache improves but returns after an initial dose of 20 mg, an additional 20 mg dose may be taken but no sooner than 2 hours after the first dose.
If the initial dose of 20 mg is not effective at all, a second dose will not likely be helpful. If the initial dose is 40 mg, a second dose is not recommended. The maximum dose of Relpax (Eletriptan) is 40 mg per day. If you need to treat more than 3 headaches in a 30-day period, talk with your doctor.
Swallow the tablet whole with water. Do not crush, chew, or split the tablets.
