Official title
Immediate Versus Delayed Initiation of Oral Contraceptive Pills After Therapeutic Abortion - A Randomized Trial
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a randomized, controlled trial investigating whether immediate versus standard, "Sunday Start", initiation of oral contraceptive pills (OCPs) in post-abortion subjects can improve compliance and the continuation of contraception. Immediate initiation of OCPs has been studied in women seeking contraception when they are not immediately post-abortion, and this "Quick Start" method has been shown to improve the continuation of OCPs into a second pill pack. The primary hypothesis of this study is that immediate initiation of OCPs in post-abortal women will improve the continuation of contraception over delayed initiation on the first Sunday after an abortion.
