It is also metabolized by CYP3A4, so inhibitors can increase its levels.","Abrupt withdrawal: Do not stop suddenly as it can precipitate seizures. Taper gradually under medical supervision.","Use in pregnancy: Associated with congenital malformations. Use effective contraception and discuss risks with your doctor.","Driving and operating machinery: May cause drowsiness and dizziness.
