A study in this month’s Annals of Pharmacotherapy compares freely available drug information in two Internet resources: user-edited Wikipedia and the “traditionally edited pharmacy-practice-specific” Medscape Drug Reference. While the information in Wikipedia was generally accurate, researchers report serious “errors of omission” in safety-related areas such as drug interactions, risks related to pregnancy, and adverse drug events. The authors cite a recent report that “the same group of 18- to 44-year-old individuals who consult resources like Wikipedia has recently been identified as the most likely to borrow and share prescription drugs without medical oversight or disclosure.”
