ABSTRACT
PIP: The performance of the monthly injectable contraceptive, Cyclofem, was evaluated in an introductory trial involving 3183 women recruited from family planning centers in Brazil, Chile, Colombia, and Peru. A total of 29,676 women-months of use were accumulated during up to 2 years of follow-up. No pregnancies occurred during the study period. Discontinuation rates per 100 women in the first year ranged from 3.4 in Brazil to 8.1 in Colombia for amenorrhea and from 5.1 in Chile to 9.2 in Brazil for menstrual disturbances. The discontinuation rate for other medical reasons (primarily headache, weight gain, and acne) ranged from 7.8 in Brazil to 26.3 in Colombia and for personal reasons from 17.2 in Chile to 23.5 in Brazil. First-year continuation rates ranged from 42.3 in Colombia to 52.0 in Chile. In the second year of use, continuation rates ranged from 19.4 in Brazil to 36.8 in Chile. Upon receiving these results, national regulatory authorities in the 4 participating countries approved Cyclofem registration. Acceptance of injectable contraception, which currently entails administration of the method by a service provider and travel to a clinic, could be improved in developing countries by training in self-administration.
