Lng IUD (medicated IUD)
The levonorgestrel (LNG) intrauterine device (IUD) releases small amounts of levonorgestrel, a form of progesterone, into the uterus each day. 
It is used for birth control, heavy menstrual periods, and to prevent excessive building up of the lining of the uterus in those on estrogen replacement therapy.
It is on the world health organization list of essential medicines, the most effective and safe medicines needed in a health system.

Effective contraception
It is one of the most effective forms of birth control with a one-year failure rate of around 0.2%. The device is placed in the uterus and lasts three to five years. Following removal, fertility returns quickly.
The IUD with progestogen is a type of long-acting reversible birth control. It works by making the mucus at the opening to the cervix thick, stopping the buildup of the lining of the uterus, and occasionally preventing ovulation.

  • 90% of users who wish to become pregnant do so within 24 months of removal
  • Effective for up to three to five years (depending on the IUD)
  • Considered one of the most effective forms of reversible birth control


  • Irregular periods and spotting between periods often occurs after insertion
