One-Year IUD Device Continuation at Time of EC

Contraception; ePub 2017 Jun 5; Sanders, et al

Two-thirds of women who chose intrauterine device (IUD) placement at the time of emergency contraception (EC) continued use at 1 year, with similar 1-year continuation rates for copper or levonorgestrel IUDs, a recent study found. The cohort study enrolled 188 women who presented at a single family planning clinic between June 2013 and September 2014 and selected either the Cu T380A IUD or LNG 52 mg IUD plus oral LNG for EC. Researchers found:

  • 177 women received IUDs: 66 (37%) chose the Cu T380A IUD and 100 (63%) chose the LNG 52 mg IUD plus oral LNG.
  • Of the remaining 147 participants at 1 year, 33 (22%) had requested removals, 13 (9%) had an expulsion and declined reinsertion, 3 (2%) had a pregnancy with their IUD in place, and 98 (67%) were still using their device.
  • Continuation rates did not differ by IUD type.
