In clinical practice, generally, more than one drug is administered. In case of occurrence of an adverse reaction, the doctor not only has to treat the adverse reaction(s), but has also to identify the offending drug(s) and advise their discontinuation. 

Most often, the doctor looks for the adverse reactions caused by the administered drugs. Quite often, similar adverse reactions can be caused by multiple drugs which are being administered; and in such cases, identification of a single drug as the culprit can stop further search for similar reactions by other drugs. 

In this pocket book, the authors have presented the common adverse drug reactions alphabetically with the causative drug in alphabetical order too. Some space has been left under each adverse reaction for updating names of newer drugs as and when they become available.
