I took Imitrex for the first and my experience started 1/2 hour after I took it. I turned very pale white,my face swelled up I could not breath heart racing so fast I thought that my heart was going to come of my chest, I then became very dizzy and very tired and my arms and legs felt so limp like they were not even there.I could not even think so I layed down and fell asleep and didn't wake up till hours later.My DR. told me I was lucky.
p.s.
Be aware of all your side affects and make sure you ask your Dr.or pharmacy about counteracting with other meds that you take if any.. Imitrex
