It evaluates virtually all new drugs and reviews older drugs when important new information becomes available on their usefulness or adverse effects. Published every other week in a four-page newsletter format, it carries no advertising and is supported entirely by subscription fees. A typical issue appraises two or three new drugs in terms of their effectiveness, toxicity, cost and possible alternatives. Occasionally, The Medical Letter publishes an article on a new non-drug treatment or a new diagnostic aid.
