Migraine Headaches Support Group
Migraine is a neurological disease, of which the most common symptom is an intense and disabling episodic headache. Migraine headaches are usually characterized by severe pain on one or both sides of the head and are often accompanied by photophobia (hypersensitivity to light), phonophobia (hypersensitivity to sound) and nausea.
You can only use two (as directed and not at the same time) and then have to stop and for me I have to wait about 2 days.
Your doctor needs to know that the imitrex did not work and should have correctly talked to you about the use of them.
To stop the rebound migraines, I'm afraid to say, is stopping the medicine and basically dealing with it. Perhaps your doctor would give you something to help you through it, but you still have to go through it.
I did read this below about Imitrex:
"Frequent Imitrex Use and Overuse Headaches
Using Imitrex two or more days a week for more than 3 months can cause medication-overuse headache, a dull or migraine-like headache that is present at least 15 days per month. You can prevent medication-overuse headache by not using Imitrex as often (per attack, per week and per month) and starting preventive treatment when necessary"

I think some doctors are more liberal about how often they let their patients use medicine, and then there are doctors who are basically drill sergents. I have the latter, and I'm very glad for that. Rebounds are a bitch!
