Sit I am an epileptic patient using tegral 200mg 1 in night half a day but I feel drowsiness and shivering in my hand please tell me solution?

Ask doc to change. The rule of thumb is treatment should not be worse than the condition itself. If you are having significant side effects, you should talk to your doc for eval..If you don't tell, doc does not know. There are many meds available for treatment of seizure, but certain meds are better for some type of seizure than others..Thus you need to talk to your doc. Good luck.
