Kyleena is the trade name for a newly approved version of the modern IUD, or intra uterine device. You may also have heard of a Mirena, they are both IUDs.
Conventional IUDs dating back to the 1950s were based on a copper insert around a plastic frame.
In 1992 Mirena was developed in Finland and established itself worldwide as an effective contraceptive and treatment option for heavy and painful periods.
Like its older sister, Mirena, the Kyleena device is a progesterone based plastic T shaped frame. It is 25% smaller in size and has around only 40% of the progesterone dose in the Mirena. It gained regulatory approval in March 2020 and is on the PBS.
What are the benefits of Kyleena insertion?
Kyleena is licensed as a reversible long-acting contraceptive, also called LARC. In most women it will lead to very light periods and lessens menstrual pain. It is particularly suitable for insertion with young women or those who have not had childbirth, and thus have a firm tight cervical canal through which the IUD is passed into the uterine cavity.
How long does Kyleena last for?
5 years.
However, it is reversible so you can easily have it removed any time if you require.
What is the chance of pregnancy with Kyleena?
The chance of pregnancy is 1 in 200 per year (0.5%). For comparison the pill is 1-2 per 100 (1-2%), Implanon about 1 in 500 (0.2%) and condoms about 5% per year.
As you’re not required to remember to take any medication or do anything, your Kyleena provides continuous protection without you having to do anything.
What side effects can occur with Kyleena?
Most patients tolerate Kyleena very well. Some women will experience persistent breakthrough bleeding which is not dangerous or heavy, but can be annoying.
Like other forms of contraception, some women are sensitive to the progesterone in the Kyleena. It is possible to have some flattening/lowering of mood, occasional problems with acne, or lowering of libido.
If you are concerned about annoying side effects you can talk with your doctor to discuss the alternatives that are available to you.
How is it inserted?
The vast majority of women will have their Kyleena inserted in the doctors rooms. A gynaecologist or an experienced GP should perform the procedure. Occasionally, patients require insertion under a general anaesthetic in hospital.
Make an appointment to discuss any gynaecological, pregnancy or fertility issues.
