I have been using Imitrex for years and the tablet 50mg will stop my migraine within an hour and I feel ready to resume my activities in about two hours. I refilled my perscription and received the new generic. It took about two hours to get relief and then several hours before I felt ready to go on with my life. I though it wasn't going to work at all at first because it was so much slower. Has anyone else experienced any problems with the generic?
