What is the British National Formulary (BNF) 84?

The British National Formulary (BNF) 84 is an evidence-informed prescribing reference jointly published by the BMJ Group and Pharmaceutical Press. It provides healthcare professionals with concise guidance on medicine selection, prescribing, dispensing, administration, and drug safety across a wide range of clinical specialties.

Introduction

The British National Formulary (BNF) 84 is one of the most widely recognized medical references used by healthcare professionals in the United Kingdom. Rather than serving as a conventional pharmacology textbook, it functions as a practical prescribing guide that supports evidence-informed clinical decision-making across a broad spectrum of healthcare settings.

Published jointly by the BMJ Group and Pharmaceutical Press under the authority of the Joint Formulary Committee, the BNF has become an essential point-of-care resource for clinicians who require concise, reliable, and regularly updated information on medicines. 

Its purpose is to help prescribers, pharmacists, nurses, and other healthcare professionals make safe and informed prescribing decisions by providing guidance on medicine selection, dosing, administration, contraindications, interactions, and monitoring.

One of the defining strengths of the BNF is its emphasis on practical prescribing. Instead of lengthy theoretical discussions, it delivers concise clinical guidance designed for rapid consultation during everyday practice. 

Healthcare professionals can quickly access recommendations on commonly prescribed medicines, prescribing considerations for special populations, adverse drug reactions, and essential safety information that supports appropriate medicine use.

BNF 84 covers medicines commonly prescribed in the United Kingdom while clearly identifying medicines considered less suitable for prescribing. 

According to the preface, the recommendations are developed using information from manufacturers' product literature, medical and pharmaceutical literature, UK health departments, regulatory authorities, professional bodies, authoritative national guidelines, expert clinical advice, and emerging medicine safety information.

Another important characteristic of the BNF is its focus on evidence-based prescribing. The editorial process involves contributions from clinicians, pharmacists, regulatory experts, and specialist advisory groups representing multiple therapeutic disciplines. 

This multidisciplinary approach helps ensure that the recommendations remain clinically relevant and aligned with contemporary prescribing practice.

Although the BNF is intended to be a comprehensive prescribing reference, the editors explicitly note that it is designed as a digest for rapid reference rather than an exhaustive pharmacology textbook. 

Certain highly specialized areas—including obstetrics, malignant disease, anesthesia, and rare diseases—are intentionally covered in less detail because clinicians working in these specialties are expected to consult additional specialist resources when necessary. Likewise, detailed prescribing information for children is provided separately in the BNF for Children (BNFc).

The September 2022–March 2023 edition (BNF 84) continues this long-established approach by integrating prescribing guidance with practical recommendations on medication optimization, antimicrobial stewardship, prescribing in renal and hepatic impairment, prescribing during pregnancy and breastfeeding, and medicine use in older adults. 

These introductory sections provide important clinical context before readers access the therapeutic chapters organized by body system.

For medical students, the BNF offers an excellent introduction to rational prescribing principles. Interns and residents can use it to support day-to-day prescribing decisions, while experienced clinicians often rely on it as a rapid reference during busy clinical practice. 

Pharmacists, nurse prescribers, and other healthcare professionals also benefit from its structured presentation of drug information, prescribing precautions, monitoring advice, and clinically relevant interactions.

Rather than replacing specialist textbooks, the BNF complements them by providing concise, clinically actionable information that can be consulted quickly at the point of care. Its organization emphasizes practical application, making it particularly valuable in hospital wards, outpatient clinics, emergency departments, community pharmacies, and primary care settings.

Following the prescribing guidance, the BNF organizes medicines into therapeutic chapters covering major body systems. According to the table of contents, these include:

• Gastrointestinal system
• Cardiovascular system
• Respiratory system
• Nervous system
• Infection
• Endocrine system
• Genitourinary system
• Immune system and malignant disease
• Blood and nutrition

• Emergency treatment of poisoning

Within these therapeutic chapters, readers will find concise prescribing information for medicines, including indications, dosing recommendations, contraindications, cautions, adverse effects, interactions, administration guidance, monitoring advice, and prescribing considerations where applicable.

Beyond its introductory prescribing guidance, BNF 84 is structured around therapeutic systems, enabling clinicians to locate medicines according to the clinical area in which they are used. Each therapeutic chapter presents concise prescribing information designed to support safe medicine selection and clinical decision-making.

The therapeutic sections cover:

1. Gastrointestinal System

This chapter includes medicines used for disorders affecting the digestive tract, including acid-related disorders, gastrointestinal motility disorders, inflammatory bowel disease, constipation, diarrhea, pancreatic disorders, liver disease, and nutritional support where appropriate. Drug monographs provide prescribing information including indications, dosing, contraindications, cautions, interactions, adverse effects, and available medicinal formulations.

2. Cardiovascular System

The cardiovascular section includes medicines used in hypertension, heart failure, arrhythmias, ischemic heart disease, anticoagulation, lipid management, and other cardiovascular disorders. Individual monographs are presented in a consistent format that facilitates rapid consultation during prescribing.

3. Respiratory System

Readers will find prescribing guidance for medicines used in asthma, chronic obstructive pulmonary disease, respiratory infections, allergic respiratory conditions, and other pulmonary disorders. Drug entries include practical prescribing advice and medicine-specific precautions.

4. Nervous System

This section covers medicines used in neurological and psychiatric practice, including analgesics, antiepileptic drugs, antidepressants, antipsychotics, anxiolytics, hypnotics, medicines for Parkinson's disease, migraine therapies, and other central nervous system agents.

5. Infection

The infectious diseases chapter provides extensive antibacterial, antiviral, antifungal, antiparasitic, and antiprotozoal prescribing information together with recommendations that support antimicrobial stewardship. Drug monographs include dosing, contraindications, monitoring recommendations, cautions, and prescribing advice where appropriate.

6. Endocrine System

This chapter contains medicines used for diabetes mellitus, thyroid disorders, adrenal disease, pituitary disorders, reproductive endocrinology, osteoporosis, and related endocrine conditions.

7. Genitourinary System

The genitourinary section includes medicines used in urinary tract disorders, benign prostatic hyperplasia, erectile dysfunction, contraception, and other urological or reproductive conditions.

8. Immune System and Malignant Disease

This section covers immunosuppressants, biological therapies, cytotoxic medicines, supportive oncology therapies, and other medicines used in immune-mediated diseases and cancer management. The preface notes that malignant disease is covered less extensively than specialist oncology references because specialist literature is expected where appropriate.
