How study of geographic epidemiology of disease can help in detection of adverse drug reactions.

Abstract

The geographic epidemiology of adverse drug reactions can often help in their recognition and in pinpointing the responsible drug. Since different countries often introduce new drugs at varying periods of time and they achieve varying degrees of popularity and use, this information may sometimes aid the epidemiologist in the search for the etiology of unwanted drug effects. Some examples where geography helped unravel the story behind certain adverse drug reactions are presented.
