A member asked:

Can 500 mg amoxicillin affect birth control effectiveness? im on low dose birth control.

A doctor has provided 1 answer

Many times this is: discussed, but studies suggest this is not likely to be the case with this antibiotic. Only rifampin , has been shown to cause this problem with birth control effectiveness.
