Can you take Plan B while you r on a antibiotic?


Rate This Answer

Plan B Studies clearly show that Rifampin decreases the effectiveness of birth control pills in preventing ovulation. Other antibiotics, particularly penicillin and tetracycline derivatives, could impair the effectiveness of birth control pills in a small percentage of women. Researchers can't rule out this possibility, but no large studies have proved such an effect.
