Imitrex a sulfa drug that is used in the treatment of migraine headaches. The medication has been on the market since 1991 when it was approved by the United States Food and Drug Administration. Imitrex is only available by prescription in most countries and is available in many doses and forms including tablet, injection, and even nasal inhalant forms all available in a variety of doses.

Interestingly, Imitrex is available without prescription in the United Kingdome. It is usually sold in 50mg doses which can be doubled if needed. There is no indication that the United States will follow suit any time soon in making Imitrex available over the counter. Perhaps much of the reason that the United States Food and Drug Administration will not allow for Imitex to be sold over the counter is that it is known to cause some unintended side effects. These may include a condition where the blood changes to a green-black color. It may have also cause a variety of heart issues including coronary artery vasospasm, transient myocardial ischemia, ventricular fibrillation, myocardial infarction, and ventricular tachycardia.

Like all medications, Imitrex can cause some unintended side effects that patients should be aware of. More common side effects include atypical sensations, vertigo, pain and pressure sensations, and fatigue. Every patient will have a unique experience with some experiencing little or nothing in the way of side effects while others experience more severe side effects, and everything in between. Patients should discuss side effects with their doctors as they occur to ensure that Imitrex continues to be the best course of treatment for each patient. generic Imitrex
