Epilepsy
"No seizures whilst on Tegretol. Extreme headaches first 4 weeks, extreme tiredness. 6 weeks after starting Tegretol hives started to appear and got worse. Blood tests showed liver enzymes were 3 times higher than usual and red blood cell counts slightly reduced. Thyroid gland swelled up also. All these were shown to be a severe allergic reaction to the drug. People should be aware of this as a possibility."
