November 28, 2012: This chapter has been re-evaluated and remains up-to-date. No changes have been necessary.

Continued use of any method of contraception is related directly to its acceptability. Advisers should be competent to give information about the efficacy, risks, side effects, advantages, disadvantages, and noncontraceptive benefits of each method.

Ignorance, especially about conditions not yet evaluated by the World Health Organization or the United Kingdom Medical Eligibility Committee, should be admitted during consultations, in which the clinician and the user, or couple, should be on equal terms: a ‘consultation between two experts’.

Too often, the combined oral contraceptive (‘the Pill’) is regarded as being synonymous with contraception. Providers everywhere should promote long-acting reversible contraceptives—injectables, implants and intrauterine methods—which can be forgotten about once administered; an essential attribute of effective continuing contraception.
