Effective contraceptive counseling requires comprehensive discussion of side effects and efficacy because these factors are critical for informed decision-making and user adherence. Understanding potential side effects helps patients prepare for and manage adverse reactions, while knowing each method’s efficacy ensures realistic expectations about pregnancy prevention. This approach respects patient autonomy and promotes method satisfaction and continuation, reducing the risk of unintended pregnancy. Focusing solely on cost or one method limits patient choice and leaves out essential information, while avoiding failure rates undermines informed consent.
