migraine
"I am 51 and suffered with migraines since about age 20; didn't get Imitrex until my early 30's.  It has saved my life, without it I was worthless for a day. Fortunately I can cut 100mg into 3 and it works for me.  I would lay down for 20 minutes and headache gone. Recently I have had to use the generic and didn't think anything of it and have found I need to take a 100mg and now I get side effects I didn't before.  Just the weird feelings from vasodilatation in my chest and sometimes my legs.  Sometimes the 100mg doesn't take it completely away. I am a nurse and will look for another alternative because I would have to pay $600 for 3 boxes out of pocket if I want the brand."
