The BNF for Children (BNFC) 2017-2018 provides essential practical information to all healthcare professionals involved in the prescribing, dispensing, monitoring and administration of medicines to children. It has been revised and revalidated to reflect changes in product availability, emerging safety concerns and shifts in clinical practice. The resource addresses a significant knowledge gap in many areas of paediatric practice by providing practical information on the use of medicines in children of all ages from birth to adolescence.
