Different things work for different people, so this is just about my own migraines. Feverfew worked best, with no side effects. Amitriptyline worked, but made me semi-conscious for most of a year. Prozac worked until it didn't and I got every side effect in the book. Feverfew.

I'm sure you'd check with your doc if you were interested in trying it, but I don't think it interacts with anything else, and it's pretty inexpensive. If it dosn't say 'standardized', there's a good chance it won't work. The capsules I took contained feverfew extract, standardized to 0.7% parthenolide, the active ingredient.

Migraines, by the way, are caused by blood vessel dilation, not constriction. Caffeine, an ingredient in some anti-migraine treatments, is a vasoconstrictor.   This page is about migraine myths

In any case, I hope things work out well for you.
