RESUMO
OBJECTIVES: 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. MATERIALS AND METHODS: 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. RESULTS: 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. CONCLUSION: We found a high satisfaction rate among LNG-IUS users mainly due to the reduction of both menstrual bleeding and dysmenorrhea.
