To the Editor Diamantouros and colleagues1 addressed the need to improve written drug information for patients. They specifically assessed the content and reading level of drug information that patients commonly receive with their warfarin prescriptions. We applaud the authors’ efforts to further understand the complex nature of communicating balanced information to patients who receive high-risk medications with a narrow therapeutic index. Budnitz et al2 reported that nearly 100 000 older Americans are hospitalized for adverse drug reactions each year and that most of these emergencies relate to 4 common medications, including warfarin.
