Can you tell me how to deal with my boyfriend's epilepsy?

Maybe tough: First, make certain he follows his doctors advice and complies with medication. He should not drive if seizures are uncontrolled, and this would also restrict use of power equipment, activities at heights, swimming or taking a bath alone. Recreational drugs, especially cocaine, amphetamines, and even alcohol could be hazardous. Attend visits with him at his neurologist.
