Dessette mono is used in the prevention of pregnancy. Dessette mono contains a small amount of one type of female sex hormone – progestogen called desogestrel. For this reason, Dessette mono is called a progestogen-only pill or a mini pill. Unlike combined contraceptives, mini pills contain only progestogen and no estrogen.
Most progestogen-only pills or mini pills act above all by preventing the penetration of sperm into the uterus, but not always prevent egg cell maturation, which is the main action of combined contraceptives. Dessette mono differs from other mini pills in that its dose in most circumstances is enough to prevent egg cell maturation. Therefore, it demonstrates high contraceptive efficiency.
Unlike combined contraceptives, Dessette mono may be used by women who do not tolerate estrogens and by breast-feeding women. The drawback of using Dessette mono is that irregular bleedings may occur. Bleedings may also not occur at all
