Women who want safe, effective contraception have many more options than they did only a few years ago. Each option must be weighed carefully according to the needs and lifestyle of each particular woman. One method that provides long-term convenience with a side-effect profile that is comparable to that of oral contraceptives is the once-a-month injectable contraceptive containing 25 mg medroxyprogesterone acetate and 5 mg estradiol cypionate. Another option is the levonorgestrel-releasing intrauterine contraceptive system that offers pregnancy prevention for 5 years. Finally, hormonal implants that release low doses of progestins have been used for more than 30 years by a total of 10 million women, and easier-to-use implants will soon be available.
