Common concerns from people taking Imitrex (sumatriptan)

Final section. Do you want to return to drug navigation?
  • I used to wait until I knew the pain was a migraine, but it took so much longer to work, now I take it at the first sign. For the last year or so, I get tired after taking it, unless I'm up and moving around, but it's better than the pain!
  • Imitrex (Sumatriptan) can make you drowsy, so avoid activities that need you to be fully alert until you know how it affects you.
