The effects of birth control may be reduced for a number of reasons. You should consult with your doctor for a more complete list or an assessment of your individual risks. Here are basic factors that may reduce the effects of birth control:

1. Inconsistent use. If you do not take your pill at the same time (+/- about 4 hours is fine) or miss any days (you may miss ONE day, but must take your birth control at the exact same time every other day of the month), your risk of pregnancy increases.

2. Grapefruits. Although this may sound strange, grapefruits actually contain properties that can lower the effectiveness of birth control.

3. Antibiotics. Although a number of recent studies show that most (if not all) antibiotics actually have no effect on the efficiency of birth control, it is still advisable to use a backup method during a course of antibiotics and for at least 3 days afterwards.

Drugs that may cause this effect include: many antibiotics (e.g., cephalosporins, chloramphenicol, macrolides, penicillins, tetracyclines, sulfas), aprepitant, bexarotene, bosentan, dapsone, griseofulvin, certain HIV protease inhibitors (e.g., amprenavir, nelfinavir, ritonavir), modafinil, nevirapine, rifamycins (e.g., rifampin), many seizure medications (e.g., barbiturates, carbamazepine, phenytoin, primidone, topiramate), St. John's wort. Ask your doctor if you should use additional reliable birth control methods while taking any of the drugs mentioned above while also taking birth control pills. Before using this medication, tell your doctor or pharmacist of all prescription and non-prescription/herbal medications you may use, especially of: thyroid hormone drugs, certain benzodiazepines (e.g., diazepam, chlordiazepoxide), prednisone-like drugs, certain antidepressants (e.g., tricyclics), beta-blockers (e.g., metoprolol), "blood thinners" (anticoagulants such as warfarin), insulin. This product can affect the results of certain lab tests (e.g., thyroid). Inform all laboratory personnel that you use this drug. Birth control pills may significantly intensify the effects of alcohol. Consult your doctor or pharmacist about this. Do not start or stop any medicine without doctor or pharmacist approval.
