The British National Formulary (BNF) and British National Formulary for Children (BNFC) provide up to date information on selecting, prescribing, dispensing and administering medicines.

How do I use the BNF app?

To get the App for the BNF for access via your device, please either click here for iPad/iPhone or here for Android.  You will be asked to enter your NHS OpenAthens account – and for some strange reason, you must have already used your Athens account on a computer first.  The App will then download – and the full BNF will be available to you. (Please note, there is a large amount of information in the App, and it may take several minutes to download, even when using a Wifi connection.)

What information is available?

The BNF/BNFC provide:

  • Guidance on prescribing
  • An overview on the emergency treatment of poisoning 
  • Notes on conditions, drugs and preparations

How does the BNFC differ from the BNF?

Since many medicines are not licensed for use in children, the BNFC contains authoritative advice on licensed as well as unlicensed and off-label use of medicines for children from birth up to the age of 18 years.

I have a paper copy of the BNF why should I use the BNF website?

The BNF website provides access to any vital information that comes to light between paper editions.

Latest updates include details of any preparations that have been launched, discontinued or amended since the latest publication of the BNF.

The BNFC provides essential practical information to help healthcare professionals prescribe, monitor and administer medicines to children.

Do I need a password?

If a computer is connected to NHSnet it automatically passes through the authentication process and no login is required.  However, an NHS OpenAthens username and password is required to access the websites from a non-NHSnet computer.
