Levonorgestrel intrauterine system (Mirena): An emerging tool for conservative treatment of abnormal uterine bleeding.

IntroductionTo study the efficacy of levonorgestrel intrauterine system (LNG-IUS; Mirena) in conservative management of abnormal uterine bleeding (AUB).Materials and methodsSeventy women between 30 and 55 years with AUB were included in a study conducted over a period of 3 years. Response was assessed monthly for first 4 months and then yearly for maximum 2 years.ResultsMirena caused a 80% decrease in median menstrual blood loss (MBL) at 4 months, 95% decrease in MBL by 1 year, and 100% decrease (amenorrhea) by 2 years. Mean hemoglobin (Hb) % showed a significant rise of 7.8% from baseline 4 months post Mirena insertion. Mirena acted as an effective contraceptive in women not using any other form of contraception. Hysterectomy could be avoided in most of the women.ConclusionMirena provides an incredible nonsurgical alternative in treatment of menorrhagia. Its effects are reversible and it is an excellent fertility-sparing device. It is also an effective contraceptive.
