Side Effects of Relpax: An Introduction

As with any medicine, there are possible side effects with Relpax® (eletriptan hydrobromide). However, not everyone who takes Relpax will experience side effects. In fact, most people tolerate the medication well. When Relpax side effects do occur, in most cases they are minor, meaning they require no treatment or are easily treated by you or your healthcare provider.
 
(This article covers many, but not all, of the possible side effects with Relpax. Your healthcare provider can discuss a more complete list of Relpax side effects with you.)
 

Common Relpax Side Effects

Relpax has been studied thoroughly in clinical trials in which the side effects of a group of people taking the drug are documented and compared to another group not taking the medicine. As a result, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine.
 
Based on these studies, the most common Relpax side effects include:
 
  • Weakness -- occurring in up to 10 percent of people
  • Nausea -- occurring in up to 8 percent of people
