I'm on brenda the pill and my doctor has just prescribed me doxycycline for acne will it have an effect on the pill?

A doctor has provided 1 answer

Doxycyline: Technically yes, but recent research says no. https://www.drugs.com/article/antibiotics-and-birth-control.html doxycycline + norethindrone (contraceptive) caution advised: abx may decr. hormonal contraceptive efficacy; best evidence for tetracyclines, ampicillin (enterohepatic recirculation possibly altered)
