Serious. These medicines may interact and cause very harmful effects. Contact your healthcare professional (e.g. doctor or pharmacist) for more information.
How the interaction occurs:
Clobazam may speed up how quickly your body processes your birth control medicine.
What might happen:
Hormonal contraceptive products (such as "the pill", the "mini-pill", Norplant, birth control injections, and the patch) may not prevent you from becoming pregnant while you are taking clobazam. Clozabam may harm your baby.
What you should do about this interaction:
You should not rely on a hormonal contraceptive agent as your method of birth control while taking clobazam. You should use an additional, non-hormonal form of birth control while you are taking clobazam and for 28 days after you stop taking clobazam. Discuss birth control options with the doctor that prescribed clobazam for you and with your gynecologist (OB/GYN). If you think that you may be pregnant, contact your doctor right away.Your healthcare professionals may already be aware of this interaction and may be monitoring you for it. Do not start, stop, or change the dosage of any medicine before checking with them first.Reference:1.Onfi (clobazam) US prescribing information. Lundbeck, Inc. December, 2013.
