Description

Product description

Levonorgestrel Powder is a known compound. Levonorgestrel is a quick-acting short-term contraceptive. The mechanism of contraception is to significantly inhibit ovulation, prevent the implantation of pregnant eggs, increase the consistency of cervical mucus and the penetration resistance of sperm, so as to play a fast-acting contraceptive effect.

Specifically, levonorgestrel binds to progesterone and androgen receptors, slowing the rate at which the hypothalamus secretes gonadotropin-releasing hormone (GnRH). This process suppresses the normal pre-ovulation surge of body hormone (LH).

Levonorgestrel Powder is an emergency contraceptive that is used to prevent pregnancy after unprotected sex or after failure of another birth control method. It works by preventing a woman's egg from fully developing. It may also prevent the attachment of the woman's egg to the wall of the uterus (womb).

Common side effects include nausea, breast tenderness, headache, and irregular menstruation (including changes in the volume and frequency of menstruation).
