How do I know if I'm allergic to a drug?
I have started taking Gabapentin 300mg twice a day for a pain disorder. I have noticed that on my right calf muscle on my right leg was red last night and was a bit itchy. Today, it is not red, but still a little itchy. I was on Gabapentin 2 years ago, 400mg twice a day for 2 weeks, and I never experienced an allergic reaction-no redness-no itching. I have no other symptoms of allergic reaction other that this localized redness and occasional itchyness. When your allergic, don't you get the redness and itchyness EVERYWHERE? Like ALL OVER YOUR BODY. Maybe I've been bitten by something. Can you shed some light on this? Can it be a common side effect that will go away with continued use? Thanks.
