The British National Formulary is authored by the Joint Formulary Committee so to cite and reference the BNF in the Harvard style it would be the following:
For the online BNF
- Organisation (Joint Formulary Committee as they still compile the data)
- Year that the site was published/last updated (in round brackets)
- Title of the entry (in single quotes)
- Title of web page (in italics)
- Available at: URL (Accessed: date)
In-text citation is either:
Joint Formulary Committee (2024) OR, (Joint Formulary Committee, 2024)
And then, if you were referring to a particular drug, e.g., amoxicillin, then your reference would include that information so it could look like this:
Joint Formulary Committee (2024) 'Amoxicillin', in British National Formulary. Available at: https://bnf.nice.org.uk/drugs/amoxicillin/ (Accessed: 21 September 2024)
If you were referencing the entire printed version then it would be the following:
Joint Formulary Committee. (2024). British national formulary 87: March - September 2024. London: BMJ Publishing; Pharmaceutical Press.
OR
