You have to go to a doctor and see what they have to say. They are the ones who can help you change out your medication.
yusuf215,
I found out I was allergic to tegretol. It makes my neck swell up and become stiff so I cannot turn it. I have had great results with Dilantin and have told my doctors I will not let them take me off of it. Ask your doctor about it.
Good luck
