A member asked:
Can amoxicillin (antibiotic) make birth control less effective?
A doctor has provided 1 answer
Yes: Any antibiotic can make birth control less effective, since the antibiotics can kill off some of the "good" bacteria in the gut that are needed to process the birth control hormones. Backup methods are important while on antibiotics.
