Abstract
INTRODUCTION: To study the efficacy of levonorgestrel intrauterine system (LNG-IUS; Mirena) in conservative management of abnormal uterine bleeding (AUB). MATERIALS AND METHODS: Seventy 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. RESULTS: Mirena 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. CONCLUSION: Mirena 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.
