Avoid using carbamazepine if you have used an MAO inhibitor (monoamine oxidase inhibitor) in the past two weeks.

If you are pregnant while taking carbamazepine, you may be closely observed by your doctor to ensure no severe side effects arise. Tell your doctor immediately if you become pregnant. Additionally, you should not breast-feed while on carbamazepine.

Furthermore, if you are taking a form of birth control, know that carbamazepine can make your birth control less effective and increase the chances of pregnancy.

You may need to avoid certain foods while using carbamazepine, such as grapefruit. Grapefruit can lead to certain side effects. Do not eat or use grapefruit products.
