Kyleena vs Skyla: Comparing IUDs  – Benefits & Side Effects

Kyleena vs Skyla Comparing IUDs  – Benefits & Side Effects

An intrauterine device (IUD) is a tiny device which is put into the uterus to prevent pregnancy.

They are a form of long-acting contraception and are the most effective type of reversible birth control.

Here is a comparison of two popular IUDs:

Kyleena

It is a 30mm long and 28mm wide IUD that contains 19.5 mg of levonorgestrel, a synthetic progestin, that is a hormone produced by the ovaries.

It releases 17.5 mcg of levonorgestrel a day. After 12 months, this rate slowly declines to 9.8 mcg per day, and after 5 years, it drops to 7.5 mcg per day.

It was originally approved by the US Food and Drug Administration on September 19, 2016.

Insertion of the intrauterine device by your healthcare provider is a nonsurgical procedure, and it generally takes just several minutes to place it in the uterus.

This IUD is to be inserted into the uterine cavity within 7 days of the onset of menstruation.

You may have to go back to your healthcare professional’s office about 4 to 12 weeks after the IUD is inserted to ensure it is in the correct position.

Skyla

It is a type of intrauterine device that is approved for 3 years and is specifically manufactured for women who haven’t had kids.

This IUD is not designed to prevent the spread of sexually transmitted diseases.

For that reason, it is recommended to be used by women in monogamous relationships.kiss sex love

It contains 13.5 mg of levonorgestrel, released at a rate of 14 mcg a day after 24 days, progressively decreasing to 5 mcg a day after 3 years.

This IUD comes in a plastic device which is manually inserted into the uterus by a doctor.
