Abstract

A non-comparative study of the Norplant contraceptive subdermal implant system was conducted in Dhaka, Bangladesh. The study was designed to evaluate the contraceptive efficacy, safety and overall acceptability of Norplant implants. Six hundred women were enrolled in the clinical trial, which began in 1985 at three study sites. Follow-up visits were scheduled at 1, 3, and 6 months after Norplant implant insertion, and every six months thereafter until removal or at the end of five years. There were no post-insertion pregnancies during Norplant implant use in this study. After five years of Norplant implant use, there was no clinically significant change in body weight, systolic or diastolic blood pressure. Less than 3% of the women ever reported having any significant medical problems such as migraine, respiratory or cardiac problems during the study. The gross cumulative continuation rate was 41.2 per 100 women at the end of five years. The two most frequently reported reasons for discontinuation during the study were menstrual problems and desired pregnancy. Of the women who completed the five-year user satisfaction questionnaire, the majority of the women (86.3%) planned to continue using contraception after study completion. Of these women, approximately one-third said they planned to use another Norplant set. The findings presented suggest that the Norplant system is a highly effective, safe and acceptable method among Bangladeshi women.
