Some drugs may interact with Enpresse (ethinyl estradiol/levonorgestrel) to cause a reduction in estrogen levels, and can therefore cause an increased incidence of breakthrough bleeding, menstrual irregularities and possibly reduce the effectiveness of the birth control.
Drugs that may interact with Enpresse include:
*rifampin
*rifabutin
*barbiturates
*phenylbutazone
*phenytoin sodium
*griseofulvin
*topiramate
*some protease inhibitors (used in the treatment of HIV)
*modafinil
*possibly St. John’s wort.
*antibiotics (such as penicillins, tetracyclines)
Do not smoke while using birth control pills, especially if you are older than 35. Smoking can increase your risk of blood clots, stroke, or heart attack caused by birth control pills.
Always check with your doctor or pharmacist before you start taking any new medication or supplement.

According to World Health Organization (WHO) medical eligibility for contraceptive use, generally we can say the following matters for OCPs interaction with other drugs:
Rifampicin or rifabutin and certain anticonvulsants (phenytoin, carbamazepine, barbiturates, primidone, topiramate, oxcarbazepine) and Lamotrigine have condition where the theoretical or proven risks usually outweigh the advantages of using the method.
Broad spectrum antibiotics (excluding rifampicin) Antifungals and Antiparasites users generally which there is no restriction for the use of the contraceptive method.
Antiretroviral drug should be checked by your pharmacist some of them have important interaction.

I just started birth control myself.. and I found out that St. Johns Wart could weaken the affect of " The Pill" and of course antibiotics do weaken " The Pill "
