Wear a Medic Alert bracelet or necklace. Carry an identification card with information about your condition, medications, and doctor. After taking primidone you may get a residual hangover effect that leaves you drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how primidone affects you. To reduce dizzy or fainting spells, do not sit or stand up quickly, especially if you are an older patient.
Alcohol can increase possible unpleasant effects.
Avoid alcoholic drinks. Use another method of birth control while you are taking primidone. If you are going to have surgery, tell your doctor or dentist that you are taking primidone. Keep out of the reach of children in a container that small children cannot open. Protect from light.
