September 1, 2008

Most women who take an OC for at least 1 year resume their regular menses or are able to become pregnant within 90 days of cessation.

Most women who take an oral contraceptive (OC) continuously for at least 1 year resume their regular menses or are able to become pregnant within 90 days of cessation, according to the findings of a recent observational study.

The study included almost 200 women between the ages of 18 and 49 years with a history of regular menses and who continuously used levonorgestrel (LNG) 90 μg/ethinyl E2 (EE) 20 μg for at least 1 year.

Of the 187 women who completed the study, 181 resumed their periods and four became pregnant (combined 98.9%) within 90 days of the last OC dose. Median time to return of menses was 32 days.
