Understanding Ella's Mechanism of Action

Ella contains ulipristal acetate, a unique compound that works differently from traditional emergency contraceptive pills. Unlike other morning-after pills that primarily use levonorgestrel, ella targets progesterone receptors in the body, effectively blocking hormonal processes that lead to pregnancy.

By interfering with the luteinizing hormone surge that triggers egg release, ella provides a more comprehensive approach to emergency contraception. Care do pregnancy tests can help confirm the effectiveness of emergency contraception if needed.

Clinical studies demonstrate that the medication maintains relatively consistent effectiveness throughout this period.

Comparative effectiveness rates show ella preventing approximately 85% of potential pregnancies when taken within the five-day window. The medication's efficacy remains impressively high, with prevention rates around 95% during the first 24 hours and over 80% even on the fifth day.
