Relpax® (eletriptan hydrobromide) is used for the acute treatment of migraine. Relpax® is in the class of medications known as triptans. More than 9,000 patients participated in the clinical trials and they treated in excess of 70,000 migraine attacks. Relpax® was effective in relieving migraine pain and the associated symptoms of nausea and sensitivity to light and sound. Side effects include fatigue, somnolence (sleepiness), nausea and dizziness. Adverse events with Relpax® are similar to adverse events for the triptan class of medications.
