Practice How to Use the British National Formulary (BNF)

The BNF serves as a valuable reference resource for prescribing information, containing a vast amount of knowledge.

You must familiarize yourself extensively with the contents of the BNF, as this will greatly benefit you in the clinical aspects of your foundation trainee pharmacist training and in preparing for the GPhC exam/registration assessment.

To help you get to know some of the BNF’s content and practice using the BNF, we have compiled a list below that highlights the various topics and subjects covered in the BNF. Following this, there is a practice quiz designed to assess your ability to locate specific information within the BNF (e.g. looking up a drug-drug interaction) and identify any gaps in your knowledge of the BNF.

Although this page is primarily intended for trainee pharmacists, other healthcare professionals like doctors and nurses undergoing their training may also find this useful.
