Brevicon Drug Interactions

Brevicon Interactions Explained

The following sections explain in detail the potentially negative interactions that can occur when Brevicon is combined with any of the drugs listed above.
Aminoglutethimide (Cytadren)
Taking aminoglutethimide and Brevicon together increases the risk of pregnancy. Do not use these medications together without first talking to your healthcare provider. You may need to use a backup method of contraception (such as condoms).
Aprepitant (Emend)
Aprepitant can make Brevicon less effective, perhaps increasing your chance of pregnancy. Talk with your healthcare provider before using these medications together. You may need to use a backup method of contraception. People undergoing chemotherapy commonly use aprepitant, and it is often very important for women having chemotherapy to avoid pregnancy.
Barbiturates
Barbiturate medications may cause your body to metabolize the hormones in Brevicon too quickly, increasing your risk of pregnancy. Ask your healthcare provider if you should use a different method of contraception while taking a barbiturate.
Certain Antibiotics
There have been reports of accidental pregnancy occurring in women taking birth control pills together with certain antibiotics. However, the significance of this interaction is still uncertain. Some antibiotics are more likely to cause problems than others. Any time you take an antibiotic, make sure to ask your healthcare provider if you need to use a backup method of contraception.
Cyclosporine (Gengraf, Neoral, Sandimmune)
Brevicon may increase the level of cyclosporine in your blood, increasing the chance of side effects of cyclosporine. Talk with your healthcare provider before taking these medications together. You may need a lower cyclosporine dose, or you may need to switch to a different method of contraception.
