Hormonal iud active ingredient levonorgestrel mirena kyleena skyla liletta?

Yes. Mirena, Kyleena, Skyla, and Liletta are all hormonal intrauterine devices (IUDs) and their active ingredient is levonorgestrel (a progestin). They differ in how much levonorgestrel they contain and how long they’re approved to stay in place:

- Mirena: about 52 mg levonorgestrel; approved for up to about 6 years.
- Kyleena: about 19.5 mg; approved for up to about 5 years.
- Skyla: about 13.5 mg; approved for up to about 3 years.
- Liletta: about 52 mg; approved for up to about 4 years (labels can vary; check current labeling).

If you want, I can compare them in more detail or help with questions about side effects and suitability.
