title: Norplant and other implantable contraceptives.
abstract: Implantable contraception represents a safe, reversible form of long-term family planning with distinct advantages. It does not contain estrogen, thus avoiding many of it contraindications. Importantly, it is extremely effective, has high continuation rates, and is well tolerated. The main side effects of Norplant are irregular menstrual bleeding and the occasional difficult removal. Although recent high-profile litigation has severely diminished enthusiasm for Norplant, the FDA has reaffirmed its safety and efficacy. Norplant remains a viable family planning option for carefully selected women. New contraceptive implants may soon be available accentuating the advantages of Norplant while minimizing the disadvantages.
