Vicodin
"I was prescribed Vicodin as a rescue med for migraine. I've only used it 3 times but have had to cease using it because it makes me itchy all over my body. I don't get a rash, just very itch, it drives me nuts. 
I was taking 2 x 10/325 tablets (after taking 4 mg Zofran). It doesn't completely take away my migraine. I can still function. I need a little nap, then I can get up and work, drive car etc. It did wonders for my neck and back pain I am currently getting physio on, but it hasn't been a wonder rescue drug for migraine. I've been given a different narcotic rescue med to try. Hopefully I won't need to use it. I am on Depakote as a preventative and use Cambia as an abortive. These both work well, especially if I take the Cambia early."
