No, I don't wear one, No, I have never received this with my medication, Yes, I would think maybe because it is an anti-seizure med. I do keep a card in my wallet with all my medications and doses listed though, and I used to wear a bracelet with my allergy to Penicillin listed, but I don't wear it anymore, although I guess I should.

I do vaguely remember maybe (my memory is totally shot) reading about a bracelet in one of the information sheets you get with drugs, but when I asked my pdoc about it she said not to worry about it. If it worry's you just ask the doctor that prescribed it.
