Mercilon is a combined contraceptive pill. Its active ingredients mimick the body’s hormones thereby tricking the body into believing ovulation has already taken place. This way the body does not release an egg and should therefore not become pregnant.
Mercilon contraceptive pill contains two active ingredients: ethinylestradiol and desogestrel. Desogestrel is one of the newer forms of synthetic progesterone. These synthetic hormones prevent ovulation, no egg should be released by the body and can therefore not be fertilised by sperm. ethinylestradiol and desogestrel also change the womb lining, making it much harder for an egg that would be released, to settle in the womb. At the same time the mucus in the womb is thickened, forming a natural barrier between the egg and sperm.
How do ethinylestradiol and desogestrel affect the menstrual cycle?
Through a combination of ethinylestradiol and desogestrel the normal menstrual cycle of the woman continues despite the lack of ovulation. The monthly menstruation takes place in the stop week of the pill. The menstrual period might be lighter and less painful when you use Mercilon. For this reason, some of these contraceptive drugs are also prescribed for women with painful period pains or irregular menstrual cycles.
How to use Mercilon?
You take Mercilon once a day. Make sure the day you take it corresponds with the day marked on the strip so you are always able to check whether or not you have taken your pill. A strip of Mercilon contains 21 pills, so you take a pill every day for 3 weeks, then you don’t take any pills in the 4th week, allowing menstruation to occur. After 28 days you start with a new strip, therefore day 29 becomes the new day 1 and you continue this for another 28 days. If you take all your pills correctly, Mercilon protects 99% against pregnancy. You are also protected from pregnancy in your stop week (days 22-28) as long as you keep losing it correctly. All Mercilon pills in the strip contain the same ingredients, therefore Mercilon is a monophasic pill.
