Eletriptan is used to treat migraines when they occur. It helps to relieve headaches, pain, and other symptoms of migraines, including nausea, vomiting, and sensitivity to light/sound. Prompt treatment allows you to get back to your normal routine and may decrease your need for other pain medications. Eletriptan does not prevent future migraines or reduce how often you may get a migraine.
Eletriptan belongs to a group of drugs called \"triptans.\" Migraines are thought to occur when certain blood vessels in the brain become swollen (dilated). This drug works by helping blood vessels in the brain to return to normal size. It may also block pain signals in the brain.

How to use eletriptan HBr Oral
Read the Patient Information Leaflet available from your pharmacist before you start using eletriptan and each time you get a refill. Ask your doctor or pharmacist if you have any questions.
Your dosage is based on your medical condition and response to treatment.
Take this medication by mouth, with or without food, at the first sign of a migraine as directed by your doctor. If there is no improvement in your symptoms, do not take any more doses of this medication before talking to your doctor. If your symptoms are only partly relieved, or if your headache comes back, you may take a second dose after 2 hours or as directed by your doctor. Do not take more than 80 milligrams in a 24-hour period. For the Canadian product: according to the drug manufacturer, do not take more than 40 milligrams in a 24 hour period.
If you have certain conditions that increase your risk of heart disease and you have never taken this medication before, you may need to be monitored for rare but serious side effects (e.g., chest pain) when you take the first dose. Your doctor may ask you to take the first dose in the office. See Precautions section for more information.
Tell your doctor if your condition does not improve or if it worsens.
Overuse of drugs to treat sudden migraine attacks can lead to worsening of headache (medication overuse headache) or rebound headache. Therefore, do not use this medication more often or for longer than prescribed. Tell your doctor if you need to use this medication more often, if the medication is not working as well, or if you have more frequent or worse headaches. Your doctor may need to change your medication and/or add a separate medication to help prevent the headaches.

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.
