    Imitrex acts on serotonin (or 5HT) receptors that are found on blood vessels in the brain, causing them to narrow. It's also thought to inhibit the action of the trigeminal nerve. These actions relieve the headache and other symptoms that you may get with your migraine, such as feeling sick or sensitivity to light or sound.

  • How does relpax work

    Relpax works by stimulating receptors called serotonin (or 5HT) receptors that are found in the brain. A natural substance called serotonin normally acts on these receptors, causing blood vessels in the brain to narrow. Relpax mimics this action of serotonin by directly stimulating the serotonin receptors in the brain. This narrows the blood vessels and so relieves the pain of migraine headaches.

  • How long does relpax stay in your system

    The half-life is about 4 hours. That means half the dose is out of your body in 4 hours. Half of the remaining half is out in the next 4 hours, etc. It takes 6-7 half-lives (24-28 hours) for all of it to be out of the body.

  • Relpax dosage

    Relpax comes as a tablet to take by mouth. Take one tablet at the first sign of a migraine headache.

    If your symptoms improve after you take the drug but return after two hours or longer, you can take a second tablet.

    If your symptoms don't improve after the first tablet, call your doctor. Don't take a second tablet before talking with your healthcare provider.

    Don't take more than 80 mg of Relpax in 24 hours.

Questions & Answers

Where to buy imitrex or relpax over the counter in the U.S.?

You can not buy imitrex and relpax without prescription in the US, Canada, UK and most other countries in the world. You need to get a prescription for migraine medications from your doctor before being able to access the meds. If you have a prescription, Walgreens, CVS, Walmart or any other online pharmacy will sell drugs for you.



Imitrex changed my life. I only take 50 mg the best part about is that after the migraine wears off the medication give me a lift of energy. Wish I had this sooner I suffered for year.


I have been on Imitrix and Maxalt, but have actually found that taking a combo of 6 mg ibuprofin and 3 mg Excedrin work better than either and it is safe to take that 3 times a week. I think that a preventative is also important.
