I recently started taking tegretol and I was not really feeling any side effects. On Friday I went up another 200mg and my doctor said I could stop taking the 75 mg of seroquel I was taking during the day. I stopped Saturday. Today is the worst day of side effects I am having. I am very nauseous, my body and lips feel slightly numb hot flashes basically I feel awful. I was thinking maybe it was from going up on the tegretol but now I am reading that it sounds like seroquel withdrawal. Has anyone had this happen. Maybe I should slowly taper off the seroquel my doctor said I should not have a problem but I always do when I withdraw from a med. I knew maybe I should ride out the withdrawals. I know tegretol can cause similar side effects but I have been taking it for a month and not had these side effects. I thought maybe it was because I went up 200 mg.
