Emergency Contraception Study
This study is being conducted at the University of Pennsylvania to test the effectiveness of three different hormonal emergency contraception pills available for women who weigh 80 kg (176 pounds) or more and who have had unprotected intercourse within the last 3 days. The emergency contraception being tested is all commercially available and would be provided to qualified participants free of charge. The emergency contraception qualified study participants may receive is Plan B One Step® (1.5 mg levonorgestrel), two doses of Plan B One Step®, or Ella® (30 mg ulipristal acetate 30 mg).
This study will investigate the safety and effectiveness of the three emergency contraception methods as compared to each other, to determine if there is a method that works best for women who are overweight and obese. This one-month study will also be looking at any health changes or side effects that may occur during the study period. Study participation involves about four phone calls and up to two in-person visits. Participants will be compensated for their time and travel for completing the visits.
