POPs are oral hormonal contraceptives containing only progestins at low doses. They prevent ovulation in 50% of cycles in lynestrenol preparation and 97% of cycles in desogestrel preparation. This process takes effect after at least seven days of regular pill intake. POPs mainly thicken the cervical mucus and impair the entry of sperm into the uterus.
- 0.5 mg lynestrenol (e.g., Exluton, Daphne)
- 75 μg desogestrel (e.g., Cerazette)
Both are available in 28-tablet packets. POPs must be taken at the same time every day. When taken even a few hours late, these pills will be less effective.
Women should first get a consultation, examination, and prescription from their midwife, nurse or doctor before taking POPs.
POPs should be taken by women as prescribed by their doctor.
Ideally, start the first pill within the first five days of the menstrual period (preferably on the first day). You can also start at any time as long as you are reasonably certain that you are not pregnant. If you start taking the pill after the first five days of your menstrual cycle, you should abstain from sex or use a backup method for the next two days.
