My neurologist prescribed carbamazepine for Trigeminal neuralgia. 100 mg. chew tabs up to 3 times a day. I took the first tab last night (20 hours ago) pain did go away, this morning I had slight pain. The pharmacist said I might want to begin with only 1 pill every 24 hours for awhile (Neurologist indicated that I could play around with 1 or 3 pills depending on how I feel) This afternoon the pain is not bad, however I feel slightly dizzy (I did not this morning) Is this normal?
