Your BNF is now only valid for 6 months

The print edition of the BNF is published every 6 months, in March and September.

It is important to use the most recent edition for making clinical decisions and so older versions should be removed from clinical areas.

Latest copies of the BNF have the period of validity printed on the front cover.

The online version of the BNF is updated every month, and is available free of charge from www.bnf.org
