I've been on Yaz for over a year, and I'm also on a daily low dose antibiotic of Macrodantin in order to prevent recurrent UTI's. It's only 50mg/day, so my doctor says I shouldn't be too worried about it lowering the effectiveness of the birth control. Maybe I'm just paranoid since I've gotten pregnant in the past, but I still make my boyfriend wear condoms like 75% of the time, and he hates it. I hate them too, we're both clean, and I take the Yaz on a rigid schedule. Should we discontinue using the condoms?
