I'm studying to be an osteopath and this truly pocket sized book is invaluable as a quick reference guide to commonly prescribed drugs, how they work and their possible side-effects. This information allows you to determine if certain treatments might be contraindicated in some patients and why certain symptoms may present. The book is small and compact enough to fit neatly into a clinic coat pocket with space to spare and the ring binding means you can keep a page open without damaging the book. It may look small but all the pertinent information is included on drugs prescribed for heart conditions, diabetes, respiratory problems and much, much more. All in all this book is brilliant and highly recommended for anyone who wants to treat safely.
