Managing clinical complexities of long-term contraception.

The 3 methods of long-term contraception (LTC) approved for use in the US are intrauterine devices (IUDs), levonorgestrel subdermal implants, and sustained-release medroxyprogesterone acetate injections. Women who use reversible LTC are likely to receive care from clinicians who did not prescribe the method of contraception originally. Fortunately, most concerns arising from the use of reversible LTC can be managed by clinicians regardless of their specialty. Problems associated with an IUD can include a missing string, partial expulsion of the device, change in menstrual pattern, vaginal discharge, or infection. Headaches, weight gain, dermatologic problems, changes in hair growth, and irregularities in menses are among the problems that clinicians may confront while caring for a woman who has had subdermal hormone implants or has been taking depot injections. Besides the problems caused by or complicating specific methods of LTC, a woman may seek clinical care for a variety of general concerns. These include a desire to terminate LTC in order to become pregnant, and physical changes that are suspected to indicate pregnancy or contraceptive failure. In addition, general health conditions such as concurrent medications, hypertension, and endocrine disorders may need special consideration in a woman using LTC. There are few medical indications for discontinuing or changing LTC, even when intercurrent illnesses arise.
