Objective: To study the acceptability, efficacy, adverse effect and user satisfaction of Levonorgestrel intrauterine system (LNG IUS) for treatment of menorrahgia. Method: This was an observational descriptive study conducted in ESI PGIMSR over a period from Jan 2008-June 2011. 70 women presented in O.P.D with heavy menstrual bleeding having no contraindication for device, consenting for LNG IUS underwent its insertion. Menstrual pattern, pictorial blood loss assessment chart score, adverse effects, and rate of acceptability and satisfaction were recorded at 3, 6 and 12 months after procedure. Results: The mean age of the sample was 39.92 yrs ± 3.27. Indication for device insertion was DUB in 81.42% (57), fibroid 8.57% (6), adenomyosis in 10% (7). The expulsion rate was 4.2% (3), removal rate was 7.14% (5) and continuation rate is 88.57% (62). 2.28% (3) patients underwent hysterectomy because of continuous bleeding even after 3 - 4 months of insertion. On follow-up at one year out of 62 patients, 33.87% (21) were amenorrhic and 51.61% (32) have regular period, while 3.07% (2) patients had irregular period. Conclusion: LNG IUS is a less invasive, effective treatment modality for menorrahgia with reasonable efficacy.
