Imitrex DF is a medication that contains the active ingredient sumatriptan. It belongs to a class of medications known as 5-hydroxytryptamine agonists, or triptans, and is primarily used to treat migraines.

Sumatriptan works by narrowing blood vessels in the brain and reducing the release of certain substances that can cause migraines, such as pain, nausea, and sensitivity to light and sound.

Use and Dosage

Read the Patient Information Leaflet if available from your pharmacist before you start taking sumatriptan 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 at least two hours after the first dose. Do not take more than 200 milligrams in 24 hours.

This medication may also be used as a backup for sumatriptan injection. If your symptoms are only partly relieved or your headache comes back, you may take a dose of sumatriptan by mouth at least two hours after the injection, up to a maximum of 100 milligrams in 24 hours.

If you have a higher risk for heart problems (see Precautions), your doctor may perform a heart exam before you start taking sumatriptan. 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 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, if the medication is not working as well, or if your headaches get worse.
