Eletriptan hydrobromide, sold under the brand name Relpax, is a medication used to treat migraine headaches with or without aura in adults [WebMD]. It belongs to a class of drugs called triptans, which work by narrowing blood vessels in the brain [MedlinePlus]. This helps to relieve headache pain, as well as other migraine symptoms such as nausea, vomiting, and sensitivity to light and sound [WebMD].
Eletriptan is only effective in treating a migraine headache that has already begun. It will not prevent headaches or reduce the number of attacks [Drugs.com].
