Imitrex is a prescription medication that is indicated in the treatment of migraine headaches. It is classified as a sulfa drug that 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 tablets, injections, as well as nasal inhalants to fulfill the treatment needs of all who suffer from these painful and life changing headaches.
Imitex 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 and it is a potent medication that needs to be used exactly as prescribed.
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. Not all patients will experience these side effects.
More common side effects include 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. Imitrex is generally very well tolerated, but for those who cannot seem to shake the side effects, a meeting with the doctor is in order to determine if there is a better course of action.
