Cerazette Tablets

Cerazette is a progestin-only pill (PPS) that contains the synthetic sex hormone desogestrel. Unlike combined birth control pills, Cerazette does not contain estrogen-type hormones. Cerazette prevents you from getting pregnant by increasing the thickness of the mucus in the neck of your womb (cervix), making it difficult for sperm to pass through. Unlike traditional progestin-only pills, Cerazette’s contraceptive effect is primarily achieved by inhibiting ovulation. Cerazette is believed to be more effective than traditional 3-hour window PPS in preventing pregnancy. It is more than 99% effective (less than 1 in 100 women will become pregnant in the first year) when taken correctly. However, this is lower (91% effective) in real life when Cerazette is not always taken perfectly.
