It was first published in 1949 as the National Formulary, with updated versions appearing every three years until 1976. The fifth version in 1957 saw its name change to "The British National Formulary". A new look version, under the auspices of Owen Wade, was released in 1981. A study in Northern Ireland looking at prescribing in 1965, reported that the BNF was likely able to serve the requirements of prescribers in general practice, while also achieving a cost saving. By 2003, issue 46 of the BNF contained 3000 interactions or groups of interactions, with about 900 of these marked by a bullet. A new edition of the BNF book is published twice-yearly; in March and September. , the current edition is 79, which was published in March 2020. It is a customary tradition that the colour of each new edition is radically different from the previous. The BNF is presently available as a book, a website, and mobile applications - the latter for use on smartphones and tablets. The book is available for purchase, and the September edition is distributed to healthcare professionals in the UK at no direct cost to them. NHS workers and healthcare professionals in the HINARI group of developing nations are entitled to free access via MedicinesComplete following registration (requires provision of a name, an address, an email address, and a phone number). Other visitors can subscribe to the BNF on MedicinesComplete. Healthcare organisations can also subscribe to a customisable BNF via their corporate online intranet. In June 2012, the National Institute for Health and Care Excellence (NICE) released applications for offline access to the BNF on iOS and Android devices. An NHS Athens log-in is required to use this application, and monthly content updates are available, over an internet connection. NICE also provides a website providing the content of the BNF to the public, including non-NHS users. The "British National Formulary for Children" (BNFC) book, first published September 2005, is published yearly, and details the doses and uses of medicines in children from neonates to adolescents. The "Nurse Prescriber's Formulary for Community Practitioners" (NPF) is issued in print every two years (September, odd-numbered years), for use by District Nurses and Specialist Community Public Health Nurses (including Health Visitors) who have received training to become nurse prescribers. The "British National Formulary" is divided into various sections; with the main sections on drugs and preparations being organised by body system.
