Kyleena

Levonorgestrel, the active ingredient in Kyleena, is a synthetic progestin presented as a 19.5 mg intrauterine system (IUS) for intrauterine use. It provides long‑acting hormonal contraception by releasing levonorgestrel locally to prevent pregnancy in women of reproductive age, with up to five years of approved use after insertion by a qualified clinician.
