Were you looking for information about Mirena? Murena is a common misspelling of Mirena.
Mirena® is a contraceptive device that is inserted into the uterus and slowly releases a certain hormone that prevents pregnancy for up to five years. This form of contraception works by stopping ovulation, altering the cervical mucus, and/or changing the lining of the uterus. There is only one standard Mirena dose, regardless of age, weight, or medical conditions. Possible side effects of the contraceptive include headaches, nausea, and a decreased sex drive.
