Mirena also known as levonorgestrel-releasing implant is an intrauterine device (IUD) placed in the uterus to prevent pregnancy. According to Mirena-us.com, it is 99 percent effective and can work for five years.
Features
Mirena is a small T-shaped plastic device inserted into the uterus via an inserter. Once inside the uterus, Mirena releases the hormone levenorgestrel, a chemical similar to what is found in the female body. According to Mirena-us.com, Levenorgestrel works to thin your womb's lining, thicken cervical mucus and prevent sperm from fertilizing an egg.
Timing
Mirena should be placed within seven days of your period's start date. Only a medical professional should insert Mirena.
Side Effects
Mirena's common side effects include spotting (vaginal bleeding at different times), headache, cramps, nausea and weight gain, according to Medscape.com. Serious side effects include trouble breathing, anxiousness and painful intercourse. Call your doctor if these or any other side effects occur.
Warning
Tell your doctor about your medical history, medications and if you are pregnant or breastfeeding.
Getting Pregnant After Mirena
If you decide to become pregnant, the device can easily be removed. According to Mirena-us.com, 80 percent of women become pregnant within 12 months of Mirena removal.
