Effectiveness of Contraceptives

Posted by Mark Abramowicz, M.D.

An article in the May 24th issue of the New England Journal of Medicine indicated that use of long-acting reversible contraceptives like intrauterine devices or depot injections of a progestin was much more effective in preventing pregnancy than use of pills, patches or an intravaginal ring, which can be used incorrectly, inconsistently or not at all. These results confirm those reported in Treatment Guidelines from The Medical Letter in 2010 in an article on “Choice of Contraceptives”. The Treatment Guidelines article reported that typical failure rates were 15% with male condoms, 8% with combination oral contraceptives, 8% with the Ortho-Evra patch, 8% with a vaginal ring, 3% with an injection of Depo-Provera, 0.2%-0.8% with an intrauterine device, and 0.05% with an Implanon implant.
