Generic Name: ELETRIPTAN - ORAL
Pronounced: (el-eh-TRIP-tan)

Relpax Oral Side Effects

Tingling/numbness, nausea, weakness, drowsiness, or dizziness may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor immediately if any of these unlikely but serious side effects occur:

  • blue fingers/toes/nails
  • cold feeling in the hands/feet


Pain/pressure/tightness in the chest/neck/jaw can occur shortly after using eletriptan. These side effects are usually not serious. However, you may not be able to tell them apart from a rare but very serious reaction related to a lack of blood flow to the heart, brain, or other parts of the body. Therefore, seek immediate medical attention if you notice any of these unlikely side effects:

  • chest/jaw/left arm pain
  • fainting
  • irregular/pounding heartbeat
  • vision changes
  • severe nausea
  • weakness on one side of the body
  • confusion
  • slurred speech
  • sudden or severe stomach/abdominal pain
  • trouble swallowing
  • bloody diarrhea


This medication may rarely cause a very serious condition called serotonin syndrome. The risk increases when this medication is taken with certain other drugs such as other "triptans" used to treat migraine headaches (e.g., sumatriptan, zolmitriptan), certain antidepressants including SSRIs (e.g., citalopram, fluoxetine, paroxetine) and NSRIs (e.g., duloxetine, venlafaxine), or a certain drug to treat obesity (sibutramine). Before taking this drug, tell your doctor if you take any of these medications. Serotonin syndrome may be more likely when you start or increase the dose of any of these medications. Seek immediate medical attention if you develop some of the following symptoms:

  • hallucinations
  • unusual restlessness
  • loss of coordination
  • fast heartbeat
  • severe dizziness
  • high fever
  • severe nausea/vomiting/diarrhea
  • twitchy muscles


A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including:

  • rash
  • itching/swelling (especially of the face/tongue/throat)
  • severe dizziness
  • trouble breathing


This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
