Add Cox2 Inhibitor to Plan B? New Data.

Access to effective oral emergency contraception is vital, now more than ever. While use of either levonorgestrel or ulipristal is endorsed by the ACOG, pharmacodynamic and clinical data does show that ulipristal has the efficacy advantage. Although the process of ovulation is directed by the LH surge, it is also put into action by prostaglandin resulting from COX2 activity. So, can the addition of a COX2 inhibitor increase the efficacy of Plan B when taken as a combo? A new study published 24 hrs ago in the Lancet provides some exciting data. We will cover this new RCT, and more, in this episode.
