Emergency Contraception: New Warnings

Yesterday, Medscape posted an article about new warnings issued in the UK regarding emergency contraception. The bumper sticker version is that some medications and herbal supplements may impair the efficacy of both levonorgestrel and ulipristal. While the US has not issued any warnings to date, the concern is a valid one, and worth consideration. My recommendation? Read and take back to your teams and your medical directors for further discussion. (Press coverage in the UK here, here and here.)
