Effectiveness
If I drink alcohol after taking
            emergency contraceptive pills, will they be less effective?
            No, alcohol does not make emergency
            contraceptive pills (also called "morning
            after pills" or "day after pills") any less effective
            at preventing pregnancy
            after sex. But because alcohol can make it harder for anyone to
            make good decisions about sex, drinking too much could put you in
            a situation where you might
            be more likely to need emergency contraception – like
            having sex without using birth control or putting the condom on wrong.
