A member asked:

Can diarrhea affect the contraceptive pill?

A doctor has provided 1 answer

No, it should not: In women taking the birth control pill regularly without missing a pill, then the effectiveness should not be altered by a GI illness. Diarrhea alone should not affect the pill. If she is experiencing vomiting (around the time she took the pill) then this might be an issue. Regardless, the pill is not 100% effective and if there is a concern about pregnancy, then check a pregnancy test!
