Medications and Drugs

Brand Names: Relpax

Generic Name: eletriptan (Pronunciation: EL e TRIP tan)

What is eletriptan (Relpax)?

Eletriptan is a headache medicine that narrows blood vessels around the brain. Eletriptan also reduces substances in the body that can trigger headache pain, nausea, sensitivity to light and sound, and other migraine symptoms.

Eletriptan is used to treat migraine headaches. Eletriptan will only treat a headache that has already begun. It will not prevent headaches or reduce the number of attacks.

Eletriptan should not be used to treat a common tension headache, a headache that causes loss of movement on one side of your body, or any headache that seems to be different from your usual migraine headaches. Use this medication only if your condition has been confirmed by a doctor as migraine headaches.

Eletriptan may also be used for purposes not listed in this medication guide.

What are the possible side effects of eletriptan (Relpax)?

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Stop using eletriptan and call your doctor at once if you have a serious side effect such as:

  • feeling of pain or tightness in your jaw, neck, or throat;
  • chest pain or heavy feeling, pain spreading to the arm or shoulder, nausea, sweating, general ill feeling;
  • sudden numbness or weakness, especially on one side of the body;
  • sudden severe headache, confusion, problems with vision, speech, or balance;

  • (if you are also taking an antidepressant) - agitation, high fever, sweating, fast or pounding heartbeats, nausea, vomiting, diarrhea, loss of balance or coordination, overactive reflexes, hallucinations, fainting.
