New findings present opportunity for hormonal IUS as an emergency contraceptive option
Written by Katie Williams, UNC/FHI 360 Fellow
A recent study conducted by a team from the University of Utah Health and Planned Parenthood Association of Utah with funding from the Eunice Kennedy Shriver National Institute of Child Health and Human Development and the National Institute of Health contributes exciting insights on the hormonal IUS as an option for emergency contraception. While more users in the United States prefer hormonal IUS compared to the copper IUD for long term contraception, providers currently only promote the copper IUD for emergency contraception as there was little to no research on efficacy of the hormonal IUS as an
emergency contraceptive method. This randomized noninferiority trial, conducted over three years with more than 700 participants ages 18-35, sought to compare the emergency contraceptive efficacy between the two methods. The results demonstrated that the hormonal IUS was a comparable, noninferior method to the copper IUD for emergency contraception. Further, the results determined the hormonal IUS to be a better alternative to the morning after pill.
