If you have stopped to read this post, the chances are that you know what BNF stands for which means that you might be a doctor, nurse, pharmacist or some sort of health-care practitioner.  I have an old dog-eared 2011 edition of The British National Formulary which is the definitive British publication providing information on the use and prescription of medicines.  For a medical doctor living in the middle-of-nowhere in Belize, this book is an essential.  If you are able to send me a later edition please email me at dra.tsang@gmail.com.  Your help would be very much appreciated!
