Reasons for satisfaction with the use of the 52-mg levonorgestrel intrauterine system.

Abstract

To assess the reasons to use, reasons they liked, satisfaction with, and possibilities of recommendation to other women of the levonorgestrel 52-mg intrauterine system (LNG-IUS) by users. A cross-sectional study was conducted at the University of Campinas, Campinas, Brazil from January to July 2021. We enrolled users who came to the clinic, and we applied a pre-tested structured questionnaire with open-ended questions. We performed descriptive analyses of the variables, assessing the level of satisfaction with, and the reasons regarding the possibility of continuing to use, the IUS. Of the 517 enrolled women, 251 (48%) were aged 35 years or older (mean age 33.9± 9.0 years), 276 (53%) were white, 14 (3%) were adolescents, 155 (30%) were nulligravidas, and 307 (59.4%) reported experiencing amenorrhea in the last 90 days. Common reasons why women liked to use the LNG-IUS included both the reduction of menstrual bleeding (419 women; 81%) and dysmenorrhea (290 women; 56.1%). Nine out of 10 users (517 women; 91%) were satisfied with the method, and the majority would recommend it to other women. We found a high satisfaction rate among LNG-IUS users mainly due to the reduction of both menstrual bleeding and dysmenorrhea.
