Madison, N.J., USA-based Pharmaceutical, Wyeth, plans to begin marketing Lybrel, its period suppression pill, in July 2007. The product comes in packs of 28 pills and contains low doses of ethinyl estradiol and levonorgestrel, two hormones that are commonly used in birth control pills. Side-effects in some women include unscheduled bleeding or spotting, which can last for a year while on the medication.
The first birth-control pill meant to put a stop to women's monthly periods indefinitely won federal approval Tuesday. Called Lybrel, it's the first such pill to receive Food and Drug Administration approval for continuous use. When taken daily, the pill can halt women's menstrual periods indefinitely and prevent pregnancies.
Lybrel is the latest approved oral contraceptive to depart from the 21-days-on, seven-days-off regimen that had been standard since birth-control pill sales began in the 1960s. The pill, manufactured by Wyeth, is the first designed to put off periods altogether when taken without break.
