Product Description

Imitrex, which is the generic formulation of Sumatriptan, is a migraine medication that belongs to the triptan class. The drug works by reducing the inflammation around the cranial arteries and veins. By the narrowing of the blood vessels around the brain, the headache can be reduced.


Imitrex tablets can only be used to alleviate a headache from a migraine attack that has already begun and cannot prevent or decrease the number of these episodes.

Furthermore, Imitrex is not indicated for treatment of normal tension headaches or any other type which is not specifically diagnosed as a migraine headache.


Imitrex is available in dosage strengths of 25 mg, 50 mg and 100 mg. It comes in the form of compressed tablets, nasal spray or injection. The accurate dosage and method of administration is advised by the healthcare provider based on the severity of the problem.

Imitrex should be taken exactly as prescribed by the medical practitioner and also by reading the instructions on the product label. The compressed tablet should be swallowed whole with a glass of water. The drug may be taken as early as the onset of the migraine attack is felt.

If there is little to no effect, the individual may take a second pill two hours after administering the first dose, without exceeding the dosage strength of 200 mg in a period of twenty-four hours. No other migraine pill should be taken within a period of twenty-four hours of taking Sumatriptan.

Modifying the dosage of Imitrex without consulting a physician can increase the risk of side effects or make the headache worse. One should also get help from the healthcare professional is there is no response to treatment.
