Brief Summary
The subdermal etonogestrel (ENG) implant, a long-acting reversible contraceptive (LARC) method, is among the most effective forms of reversible contraception and thus, an important tool in the quest to reduce unintended pregnancy. However, despite overall increases in LARC use in the United States from 1.5% in 2002 to 7.2% in 2011, and 11.6% most recently in 2015, implant use continues to make up a small proportion of LARC use. While evidence to explain this low uptake of implants is lacking, one potential reason is patient and provider concerns about unpredictable bleeding. As a result of this, many studies have been performed in attempts to discover therapies for unscheduled bleeding in progestin-only contraceptive users. Some of these studies include those investigating selective progesterone receptor modulators, such as mifepristone and ulipristal acetate (UPA), which did find some benefit. Although a previous study showed mixed benefit, the investigators feel that this medication has demonstrated both biologic plausibility as well as clinically important outcomes. This previous study may not be entirely translatable to the proposed research as therapies were used for different indications (prophylaxis vs. treatment) and different progestins and delivery systems were studied. Therefore, the investigators believe UPA should not be discounted as a potential therapy. UPA may provide an additional safe and effective option for treatment of irregular bleeding with implants in women. In addition, UPA is currently available in outpatient pharmacies in the U.S. as a single 30mg oral tablet. The investigators propose to investigate UPA for the treatment of unscheduled and troublesome bleeding in ENG implant users.

30 days
Secondary Outcomes (4)
Number of Participants With Bleeding Cessation by Day 10
10 days
Participant Satisfaction With Bleeding Pattern at 30 Days
30 days
Number of Participants With Medication Side Effects by 30 Days
30 days
Ovulation Status Measured by Weekly Serum Progesterone Levels
Baseline, weeks 1, 2, 3, 4
Study Arms (2)
Ulipristal Acetate
EXPERIMENTAL15mg ulipristal acetate (capsule) daily for 7 days
Placebo
PLACEBO COMPARATORIdentical placebo (capsule) daily for 7 days
Interventions
Women who have bothersome bleeding with the etonogestrel implant will be randomized to receive ulipristal acetate versus placebo daily for 7 days.
