Why is Imitrex prescribed?

Sumatriptan (Imitrex) is prescribed as a treatment of neurological conditions that causes debilitating pain in patients such as acute migraine.

What does it do?

Enlarged blood vessels in the brain may lead to acute migraine that causes pain and inflammation of the tissues present in the brain. Some vasoconstricting medications help in alleviating such pain and one of these is Sumatriptan.

Sumatripan, an agonist of serotonin 5-HT receptor, is an anti-migraine agent that works by activating the cranial arteries present in the central nervous system, thus, promoting vasoconstriction that helps in stopping excess blood flow.

How should I take it?

Imitrex is available in 25mg, 50mg and 100mg tablets. It is intended for oral administration as a whole, not to be crushed or chewed, and should be taken with or without food intake as directed by the doctor.

The dosage strength depends on every patient’s condition and the doctor’s prescription. It is strictly advised that you do not self-medicate and only take this drug after consulting with your doctor or pharmacist to determine the best dosage and dosing schedule for the treatment of your condition.

Note: Imitrex should not be taken for more than 2000mg (2g) in a 24-hour period. Consult your doctor for a proper dosing schedule.

What if I missed a dose?

Taking the dose properly at the scheduled time is needed to attain the desired effects of the drug. Sumpatriptan does not have any daily dosing schedule as it is only taken when needed. Consult your doctor for more information on proper dosing schedule.

What are the special precautions before using Imitrex?

Before taking Sumatriptan, tell your doctor or pharmacist if you have any allergies to food and to the drug itself as it may contain several inactive ingredients, which can cause allergic reactions or problems.

Inform your doctor about your past and current medical history especially if you have or have had coronary artery disease, stroke, liver disease, Wolff-Parkinson-White syndrome, seizure, high cholesterol or diabetes.

Avoid drinking alcohol as this may cause dizziness and drowsiness and can add to the effects of Sumatriptan.

Consult your doctor regarding all the other medications you use before getting a surgery.
