Innovations in contraception: the Norplant system.
The Norplant (Huhtamaki Oy/Leiras Pharmaceuticals, Turku, Finland) contraceptive system is a safe, highly effective, reversible method of hormonal contraception. The system consists of six flexible match-size implants that are implanted in the inner aspect of the upper arm. This sustained-release system delivers the progestin levonorgestrel at levels sufficient to prevent pregnancy for as long as 5 years. Norplant is a convenient, easy-to-use method. Adequate counseling of potential users and appropriate selection of patient users are important determinants of patient satisfaction with Norplant.
