So, what is Mirena? Mirena is a long-term birth control implant that gets inserted into the uterus, or so called intrauterine device (IUD). It is made of a small “T-shaped” flexible plastic device, which releases small doses of progestin hormone for the period of five years. The hormone thickens cervical mucus, thus making it harder for the sperm to reach the egg. This IUD is very easy to insert, but the doctor should perform the insertion after your pelvic was completely examined. The doctor will advise you if you are a good or a bad candidate for Mirena. The effectiveness of IUD starts immediately, as long as the insertion happens within seven days after your period started. This apparatus can be left in the uterus for the period of five years and can be removed any time before the expiry date. Considering the length of this contraceptive, the cost is quite reasonable. It could range between $150 – $500 for the insertion, the device, the exam and the follow up visit.
Birth control implants, like any other medications can cause side effects. Everybody is different, so you may or may not have reactions toward this device. The most common disadvantage of Mirena is breakthrough bleeding or spotting between periods. However, for women with heavy periods, it helps to decrease or moderate menstrual flow. Other possible side effect that you may encounter is acne, but it should disappear within the period of three month. Certain type of women might experience severe side effects when Mirena is removed, also known as Mirena Crash.
This Intra uterine device was designed only to prevent pregnancy. Similar to birth control pills, it will not protect you from any sexually transmitted diseases (STDs).
