RESUMO

Objectives: The study was conducted to assess the prevalence of local signs and symptoms at the insertion site in the arm, and the evaluation of the women s satisfaction with the method and with the new bleeding patterns among users of subdermal releasing-implants, levonorgestrel (LNG, Jadelle®) and etonogestrel (ENG, Implanon®) systems. Methods: A total of 226 and 233 women were enrolled in the ENG and the LNG group, respectively. Local signs were evaluated and women were questioned regarding complaints related to the insertion site at 14 days and 3, 6, 12, 24, and 36 months after insertion in Brazil and Dominican Republic. The same Brazilian women were randomly enrolled in the satisfaction study of ENG group (120) and the LNG group (127), respectively. The opinion of satisfaction with the bleeding pattern and with the method was evaluated through a questionnaire developed for the study. The questionnaires were applied face- toface at the 3, 6, and every 6 months thereafter up to 36 months after insertion. Results: Pain and other symptoms (mostly pruritus) were the most frequently reported complaints (~20%), and were observed in a similar proportion among both Implanon® and Jadelle® users; paresthesia was less frequently reported. Hyperpigmentation was three fold higher among users of Jadelle® than Implanon® users (p<0.0001) and was more prevalent among non-white users. All symptoms and signs were reported much more frequently by Dominican women. The logistic regression model adjusted by race and body mass index (BMI; kg/m2) showed that users of Implanon® and white women presented lower risk of hyperpigmentation when compared to Jadelle´s users (OR 0.26, 95% CI 0.14-0.48; OR 0.34, 95% CI 0.14-0.81, respectively). There was no relation between pain, paresthesia and hiperpigmentation and the use of the implants. Hiperpigmentation was more prevalent between users of Jadelle® in non-white women. The total number of questionnaires for the satisfaction study was 1,200. The results showed that most of these users of contraceptive implants were satisfied with both implants at the different visits and the regret with the method did not reach ~15% at any time through the 3 years of observation. In addition, almost 70% of the women declared that the use of the implants offered benefits for her and only ~5% referred that the use provoke harm for her. Regarding the women s response to changes in their bleeding patterns following insertion of the implant, the percentage who stated that they were very satisfied or satisfied was 70% in both methods. There was no change in the reported frequency of sexual interc urse during use of the implants and no change in their libido. Moreover, all the women in both groups stated that they would recommend the method to a friend or relative and most of them declared that their partner approved of this contraceptive method. Conclusions: Although information relating to local symptoms and signs at the implant site should be provided to current and potential users as a component of good quality of care, we do not recommend evaluation of the insertion site at every visit in women with no complaints. The results about satisfaction with the method are in agreement with previous findings. However, the results must be interpreted with caution because the women are participating in a research study and were not common clients of a family planning clinic. We cannot ignore the possibility that the high satisfaction was a consequence of dissatisfaction with alternative methods
