Principles of drug prescribing in infants and children. A practical guide.

Abstract

Paediatric prescribing is much more complicated than prescribing for adults. The specific and general aspects of paediatric patients, the limitations of commercially available dosage formulations, the vagaries of administering medicines, the general inadequacy of clinical pharmacology training, and the dearth of information about drug use in children all add to the difficulties facing the practitioner who treats infants and children. For these reasons practitioners should prescribe judiciously, select carefully the safest dosage regimen available, and educate their patients, caregivers and staff about their choices and expected positive and negative effects. Practitioners should also have available and use written, electronic, as well as human sources of expert advice. They should write all prescriptions legibly and carefully, document their therapeutic decisions and plans, and carefully monitor their patients' responses to therapy. Careful attention to the principles of clinical pharmacology can do much to improve the efficacy of paediatric prescribing and decrease its costs and risks.
