I have known epileptics who drink. They don’t seem to have seizures as a result of drinking. However, they don’t seem to drink a lot – perhaps one or two beers or a glass of wine. Certainly your liver and your doctor would appreciate it if you didn’t drink to excess.
Here is what epilepsy.com says about it:
“In small amounts, alcohol does not cause seizures. A drink or two now and then does not increase seizure activity. Nor does it alter the amounts of seizure medicines in your blood or change findings on EEG studies. When alcohol is related to seizures, it has been found that it is nearly always the state of alcohol withdrawal that aggravates seizures, rather than drinking itself. Your risk of seizures may be much higher after consuming three or more alcoholic beverages. These alcohol withdrawal seizures may begin between 6 and 72 hours after you stop drinking. Studies suggest that alcohol withdrawal seizures most often occur 7 or 8 hours after heavy or prolonged drinking has stopped.
Seizure medicines can seriously lower your tolerance for alcohol, so the immediate effects of alcohol consumption are greater. The rate of intoxication is far higher among people taking seizure medicines. Rapid intoxication is extremely problematic because many of the side effects of these medicines, which can be made worse by alcohol, are similar to the acute effects of alcohol itself. If you are sensitive to the adverse effects of alcohol or seizure medicines, you may find the combination especially troublesome. For example, the side effects of Tegretol (carbamazepine), including dizziness, drowsiness, and headache, could be enhanced by alcohol. Combining those effects with the adverse effects of alcohol, including slurred speech, unsteadiness, dizziness, and fatigue, can be extremely dangerous.”
