The different types of IUDs

October 31, 2017 by Allison Andrews WHNP

There are two different types of IUDs: hormonal and non-hormonal.
We want to answer the 2 main questions that many women ask themselves when considering an IUD:  What is the difference? Which one is right for me?

Mirena is the hormonal IUD that has been around the longest, and is currently approved for up to 5 years. Mirena was originally intended for women who have had children. However, studies have shown that it is perfectly safe and effective for women who have never been pregnant. Mirena is recommended to help manage women who suffer from heavy or painful periods. Most women on Mirena have reported that their periods get significantly lighter or go away completely. About one in five Mirena users stop having a period after a year, and one in three if they use it for a longer period of time.

Liletta is very similar to Mirena. It contains the same dose of hormone and is approved for use up to 4 years. This IUD has also been approved for women who have never had children. Like the Mirena, your periods can get significantly lighter or go away completely.

Kyleena is smaller in size then the Mirena and has a lower dose of hormone then the Mirena/Liletta. Like the Mirena the Kyleena is approved for up to 5 years and about 1 in 8 women who use it will stop having periods after a year.

All hormonal IUDs prevent pregnancy by releasing a small amount of a progestin hormone called levonorgestrel each day. The progestin acts locally in the uterus to prevent pregnancy. Hormonal IUDs do not contain estrogen and typically have fewer hormonal side effects than methods that do contain estrogen.

ParaGard contains no hormones and is approved for up 10 years. Since this device does not contain hormones, most people who use ParaGard can experience heavier, longer, or painful periods. Studies have shown that after 6 months, many ParaGard users’ periods return to normal. If you already have really heavy or painful periods, you will most likely benefit more from a hormonal IUD.

The non-hormonal IUD prevents pregnancy by using a tiny copper filament wrapped around the T. ParaGard, making the uterus a hostile environment.

IUDs are safe, effective, and reversible. There are many different kinds of IUDs and they are not a one-size-fits all. Call today to schedule a consultation with one of our nurse practitioners and together we can decide which is best for you!
