Eletriptan is used to treat migraines.
General information
Relpax helps to relieve headache, pain, and other migraine symptoms including nausea, vomiting, sensitivity to light/sound . Prompt treatment helps you return to your normal routine and may decrease your need for other pain medications. Eletriptan belongs to a class of drugs known as triptans. It affects a certain natural substance serotonin that causes narrowing of blood vessels in the brain. It may also relieve pain by affecting certain nerves in the brain. Please note that eletriptan does not prevent future migraines or lessen how often you get migraine attacks.
Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not take this medicine in larger or smaller amounts or for longer than recommended. If your headache does not completely go away, or goes away and comes back, take a second tablet 2 hours after the first. Do not take more than 80 mg of eletriptan in 24 hours. If your symptoms have not improved, contact your doctor before taking any more tablets. Call your doctor if your headache does not go away at all after taking the first Relpax tablet. Never use more than your recommended dose. Overuse of migraine headache medicine can make headaches worse. Do not take migraine headache medication for longer than 10 days in any 1 month. Tell your doctor if the medicine seems to stop working as well in treating your migraine attacks. If you use Relpax long-term, your heart function may need to be checked using an electrocardiograph or ECG sometimes called an EKG . This will help your doctor determine if it is still safe for you to take Relpax.
Certain foods, beverages, or food additives such as red wine, cheese, chocolate, monosodium glutamate as well as lifestyle patterns such as irregular eating/sleeping habits or stress may bring on a migraine headache. Avoiding these "triggers" may help lessen migraine attacks. Before taking Relpax, tell your doctor if you have liver or kidney disease, high blood pressure, a heart rhythm disorder, or coronary heart disease or risk factors such as diabetes, menopause, smoking, being overweight, having high cholesterol, having a family history of coronary artery disease, being older than 40 and a man, or being a woman who has had a hysterectomy . Do not take Relpax within 24 hours before or after using another migraine headache medicine. Do not use Relpax within 72 hours before or after taking: clarithromycin, itraconazole, ketoconazole, nefazodone, ritonavir, or nelfinavir.
Before taking eletriptan, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. You should not take Relpax if you have any history of heart disease, or if you have angina, blood circulation problems, lack of blood supply to the heart, uncontrolled high blood pressure, severe liver disease, ischemic bowel disease, a history of a heart attack or stroke, or if your headache seems to be different from your usual migraine headaches.
Possible side effect
Contact your doctor right away if you have any serious side effects such as blue fingers/toes/nails, cold hands/feet. Relpax can commonly cause chest/jaw/neck tightness, pain, or pressure that is usually not serious. However, these side effects are like symptoms of a heart attack, which may include chest/jaw/left arm pain, shortness of breath, or unusual sweating. Get medical help right away if these or other seriousfast/irregular heartbeat, fainting, severe stomach/abdominal pain, bloody diarrhea, signs of a stroke such as weakness on one side of the body, trouble speaking, sudden vision changes, confusion . This medication may increase serotonin and rarely cause a very serious condition called serotonin syndrome/toxicity. A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling especially of the face/tongue/throat , severe dizziness, trouble breathing.
Drug interactions
Avoid taking certain medications that can affect the removal of eletriptan from your body within 72 hours of taking eletriptan. Examples include cobicistat, nefazodone, azole antifungals such as ketoconazole/itraconazole, macrolide antibiotics such as clarithromycin/erythromycin, certain hepatitis C virus protease inhibitors such as boceprevir/telaprevir, HIV protease inhibitors such as nelfinavir/ritonavir, among others. If you also take any ergotamine medication such as dihydroergotamine or other "triptan" drugs such as sumatriptan, rizatriptan , separate your eletriptan dose at least 24 hours apart from your dose of these other medications to lessen the chance of serious side effects. The risk of serotonin syndrome/toxicity increases if you are also taking other drugs that increase serotonin. Examples include street drugs such as MDMA/"ecstasy," St. John's wort, certain antidepressants including SSRIs such as fluoxetine/paroxetine, SNRIs such as duloxetine/venlafaxine , among others. The risk of serotonin syndrome/toxicity may be more likely when you start or increase the dose of these drugs.
Missed dose
Since Relpax is used as needed, it does not have a daily dosing schedule. Call your doctor promptly if your symptoms do not improve after using this medicine. After taking an Relpax tablet, you must wait 2 hours before taking a second tablet. Do not take more than 80 mg of eletriptan in 24 hours.
Seek emergency at once if you have an overdose.
