Answer

Lybrel is the first FDA-approved oral contraceptive with 365-day combination dosing. [14] It contains a low combined daily dose of the hormones levonorgestrel and ethinyl estradiol (90 mcg and 20 mcg, respectively). It provides women with more hormonal exposure on a yearly basis (13 additional weeks of hormone intake per year) than conventional cyclic oral contraceptives that contain the same strength of synthetic estrogens and similar strength of progestins.

The incidence of pill failure that results in pregnancy is approximately 1-2% per year (1-2 pregnancies per 100 women per year of use) if taken every day as directed. The average failure rate is approximately 5% per year (5 pregnancies per 100 women per year of use), including women who do not always take the pill exactly as directed without missing any pills.
