The effects of antibiotics on birth control pills may be overstated — except in the suitcase of one antibiotic, rifampin. Studies clearly show that rifampin decreases the value of birth control pills in preventing ovulation. However, rifampin isn't a widely used antibiotic. Chances are you wouldn't be taking it unless you have tuberculosis or had tested positive for the disease.

Hypothetically speaking, other antibiotics, expressly penicillin and tetracycline derivatives, could impair the effectiveness of birth control pills. However, no massive studies have proved such an effect.

Researchers can't rule out the possibility that a small percentage of women may experience decrease effectiveness of birth control pills while taking an antibiotic. And if you're taking a newer, extremely low-dose oral contraceptive, you could be more susceptible to these potential effects from antibiotics. If you're concerned, consider using a line of defence method of contraception for the duration of your antibiotic prescription.

The time constraint is not competent to be determined. Antibiotics might decrease the worth of birth control pills (BCPs). Although there hold been reports of pregnancy surrounded by women who have taken antibiotics while using BCPs, the relationship have not been amply studied to date. Theoretically, additional medication might alter the metabolism and blood levels of the birth control hormones, thereby altering their worth. Thus, it is not positively proven that antibiotics are a problem with BCPs, especially when BCPs are not 100% successful against pregnancy.
