Table of contents:
Imitrex DF is an oral medication used to treat migraine headaches. Its active ingredient is sumatriptan succinate, which belongs to a class of medications known as 5-hydroxytryptamine agonists (also called "triptans"). It works by narrowing the blood vessels in the head, which helps to reduce the pain associated with migraines.
Imitrex DF is usually taken at the onset of a migraine headache, and can help relieve the pain, sensitivity to light and sound, and other symptoms associated with migraines.
Use and Dosage
Sumatriptan comes in the form of a tablet and is taken orally, usually once a day with or without food. To use Sumatriptan tablets, swallow the tablet whole with a drink of water. Do not crush or chew the tablet, as this can alter its effectiveness. If you have difficulty swallowing tablets, some Sumatriptan tablets may have a score line to help you break it in half.
You may take the tablet with or without food. The recommended dose is usually 50mg or 100mg, depending on your doctor's instructions. It is typically recommended to take the tablet at the onset of a migraine headache for the best results. Always follow your doctor's instructions and read the patient information leaflet that comes with the medication. These instructions may vary depending on the brand and formulation of Sumatriptan tablets that you are using.
