With so many options available for contraception, it can be hard to choose one that works best for you. One choice is an intrauterine device (IUD) that a provider inserts into the uterus during an in-office procedure. One of these IUDs is Mirena.
Function
Mirena delivers a hormone, levonorgestrel, to the uterus. Levonorgestrel helps prevent pregnancy by thickening cervical mucus, thinning the uterine lining and keeps sperm from reaching an egg.
Significance
According to the Mirena website, more than 12 million women worldwide have chosen Mirena as their contraceptive option and more than 2 million women in the United States use Mirena.
Time Frame
Mirena is placed in the uterus by a health care provider and can remain in the uterus for up to five years while maintaining its effectiveness. Fertility returns after the device is removed.
Side Effects
Some side effects women might experience include cramping, dizziness and bleeding. For the first few months, light bleeding is common. Many women eventually stop menstruating while Mirena is in place.
Benefits
A major benefit of Mirena is the convenience. There is no need to remember to take a daily pill or insert a monthly ring. All that has to be done is monthly checking of the threads.
Warning
Mirena does not protect against sexually transmitted diseases or HIV. Current or past health problems, your sexual history and your general health habits can factor into the decision to choose Mirena, and it is best to discuss the possibility of using Mirena with your provider.
