Compiled with the advice of clinical experts and continually updated to reflect the latest evidence from credible sources worldwide, the new edition of the British National Formulary 79 (BNF) provides up-to-date guidance on prescribing, dispensing, and administering medicines. Access to the latest edition of the BNF is vital for healthcare professionals, as it reflects current best practice as well as legal and professional guidelines relating to the uses of medicines. NICE has accredited the editorial process used by the British National Formulary to produce its resources.
