Kyleena

Levonorgestrel, the active ingredient in Kyleena, is a Progestin (hormonal contraceptive) presented as a 19.5 mg intrauterine system for intrauterine use. It prevents pregnancy by providing continuous local hormone release that suppresses endometrial growth, thickens cervical mucus and impairs sperm function.

GNH USA supplies Kyleena as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Kyleena, a levonorgestrel‑releasing intrauterine system, is indicated for hormonal contraception.
