The best amount is the amount that completely controls seizures without causing troublesome side effects. It depends on many factors, which are different for every individual. Follow the doctor's directions. Call if you have any questions.

To avoid unwanted side effects, the doctor will prescribe a low dose to start and increase it gradually until the seizures are controlled or side effects become too troublesome.

No one should stop taking Tegretol-XR or change the amount they take without talking to the doctor first. Stopping any seizure medicine all at once can cause a problem that may be life-threatening.

Don’t use more Tegretol-XR than the doctor prescribes. If a little extra (such as one or two extra tablets) is taken by accident, call the doctor for advice. For a larger overdose, call a poison control center or emergency room right away, unless you have special instructions from the doctor.
