Levonorgestrel (intrauterine Delivery System)

Introduction

Levonorgestrel (intrauterine delivery system) is a long-acting reversible contraceptive device used primarily for birth control and management of heavy menstrual bleeding. It is a hormone-releasing intrauterine system (IUS) that is inserted into the uterus by a healthcare provider. Once in place, it releases small amounts of the hormone levonorgestrel daily, which helps prevent pregnancy for up to 3–5 years depending on the brand. This device is convenient, effective, and does not require daily attention, making it a preferred contraceptive method for many women.
