A member asked:

Can amoxicillin decrease the effectiveness of the pill (birth control)?

5 doctors weighed in across 3 answers

Yes, possibly: Other than Rifampin,pharmacokinetic studies of other antibiotics have not shown any systematic interaction between antibiotics and BC pills. However, individual patients do show large decreases in the blood concentrations of ethinyl estradiol when they take certain other antibiotics, notably tetracycline and penicillin derivatives (like amoxicillin). Use a backup method of contraception(condoms)!!

No: Amoxicillin is mainly distributed in all fluids of the body.
