Update on contraception: benefits and risks of the new formulations.

Several new contraceptives have become available to women in recent years. These new agents include ultra-low-dose oral contraceptives as well as injectable, vaginal, and patch formulations. We review these, with emphasis on the Yasmin pill (which contains a new progestin), the Lunelle once-a-month injection, the Ortho Evra patch, the NuvaRing vaginal ring, the Mirena intrauterine device, and emergency contraceptive kits. Patient education regarding these options is essential for patient compliance and satisfaction.
