Levonorgestrel intrauterine system (LNG-RIS) is a highly effective, safe, and reversible contraceptive method. It suppresses endometrial cell proliferation, thickens cervical mucus, disrupts tubal motility by creating a high levonorgestrel concentration in the endometrium. In our country, LNG-RIS is mostly used in Gynecology and Obstetrics clinics and it is prescribed with the diagnosis of dysmenorrhoea among the ICD-10 diagnostic codes used in hospitals in exchange for a drug report. Its protection is high (99.9%), and its contraceptive effect is considered to last five years, and fertility returns rapidly after removal.
