A controversial question.
Macrobid is not an "enzyme inducer" - enzyme inducers reduce the effectiveness of birth control pills. So in theory it should not reduce the pills effectiveness.
However, until more is known, most doctors recommend while taking Macrobid an additional method of contraception is required eg. condoms.
Better to be safe than sorry!
