(Newser) – The FDA yesterday approved Lybrel, the birth control pill designed to stop women's periods for as long as they're on the medication, the AP reports. Unlike most other contraceptive pills, which consist of  21 daily doses of hormone treatments and 7 days of sugar pills, Lybrel contains 28 daily doses of low-dose hormones.

Not everyone was thrilled with the drug, manufactured by Wyeth, the FDA reported: About half the participants in the drug trials dropped out before they were completed, citing unpredictable breakthrough bleeding, or spotting.
