Why would my MD prescribe tegretol if I had a normal EEG. I have sleep troubles?

?restless leg. Although tegretol is used to treat seizures it is also used for other conditions such as bipolaar disorder and restless leg syndrome. If you are having sleep disturbances then I suspect that your doctor prescribed it to treat restless leg and help with your sleep. Restless leg occurs at night and can interfere with sleep.
