Read the Patient Information Leaflet available from your pharmacist before you start using eletriptan and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with or without food as directed by your doctor, at the first sign of a migraine. The dosage is based on your medical condition and response to treatment. If there is no improvement in your symptoms, do not take 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 another dose two hours after the first dose. For the US product, do not take more than 80 milligrams in a 24-hour period. For the Canadian product, the manufacturer recommends a maximum of 40 milligrams in a 24-hour period.

If you have a higher risk for heart problems (see Precautions), your doctor may perform a heart exam before you start taking eletriptan. He/she may also direct you to take your first dose of this medication in the office/clinic to monitor for serious side effects (such as chest pain). Talk to your doctor for details.

If you are using drugs for migraine attacks on 10 or more days each month, the drugs may actually make your headaches worse (medication overuse headache). Do not use medications more often or for longer than directed. Tell your doctor if you need to use this medication more often, or if the medication is not working as well, or if your headaches get worse.
