Tegretol

The coating of the Tegretol-XR tablet is not absorbed and passes through your body intact. If you notice it in your stool, it is not a cause for alarm.

Possible food and drug interactions when taking Tegretol

The use of the antiseizure medications phenobarbital, phenytoin (Dilantin), or primidone (Mysoline) may reduce the effectiveness of Tegretol.
