Nonadherence with drug recommendations (see also Factors Affecting Response to Drugs: Adherence to a Drug Regimen) may occur at any age because of cost; painful or inconvenient administration; or the need for frequent doses, complex regimens, or both. But many unique factors contribute to nonadherence in children. Children < 6 yr may have difficulty swallowing pills and may resist taking forms of drugs that taste bad. Older children often resist drugs or regimens (eg, insulin, metered-dose inhalers) that require them to leave their classes or activities or that make them appear different from their peers. Adolescents may express rebellion and assert independence from parents by not taking their drugs. Parents or caregivers of younger children may only partially remember or understand the rationale and instructions for taking a drug, and their work schedules may preclude their being available to give children their scheduled doses. Some may wish to try folk or herbal remedies initially. Some caregivers have limited incomes and are forced to spend their money on other priorities, such as food; others have beliefs and attitudes that prevent them from giving children drugs.
To minimize nonadherence, a prescribing provider can do the following:
Adolescents in particular need to feel in control of their illness and treatment and should be encouraged to communicate freely and to take as much responsibility as is possible for their own treatment. Regimens should be simplified (eg, synchronizing multiple drugs and minimizing the number of daily doses while maintaining efficacy) and matched to the patient's and caregivers' schedules. Critical aspects of the treatment should be emphasized (eg, taking the full course of an antibiotic). If lifestyle changes (eg, in diet or exercise) are also needed, such changes should be introduced incrementally over several visits, and realistic goals should be set (eg, to lose 1 of 14 kg [2 of 30 lb] by a 2-wk follow-up visit). Success in achieving a goal should be reinforced with praise, and only then should the next goal be added. For patients who require expensive long-term regimens, a list of pharmaceutical patient-assistance programs is available at www.needymeds.org.
