MIRENA® is primarily used for contraceptive purposes, although it has other health purposes as well, such as helping with heavy menstrual bleeding. It is a highly effective contraception product designed to provide women with a reliable and long-lasting solution for planned family outcomes.

This T-shaped plastic intrauterine device (IUD) will release a low dose of levonorgestrel, a progestin hormone drug, directly into the uterus. This IUD can prevent pregnancy for up to 8 years and requires replacement at the end of the eighth year.

According to the information from Bayer, the precise local mechanism by which continuously released levonorgestrel contributes to Mirena’s contraceptive effectiveness has not been definitively established.

Nonetheless, MIRENA® inhibits ovulation, the process where the ovary releases an egg for fertilization. By suppressing ovulation, MIRENA® significantly reduces the likelihood of conception.

In addition to inhibiting ovulation, MIRENA® contributes to preventing pregnancy through thickening cervical mucus. This thickening is a physical barrier, making it more challenging for sperm to go through the cervix and reach the egg.

Moreover, MIRENA® is a drug that changes the uterine lining, creating an environment less conducive to embryo implantation.
