The Health Tools portion of the AARP website addresses questions about Medicare, drug interactions, and where to find cheaper medicines. There is even a "Doughnut Hole Calculator" for those visitors with Medicare Part D who are worried about a coverage gap. The "Pill Identifier" tool helps visitors avoid medication mix-ups, by allowing for searches by "imprint", "shape", or "color" of the medicine. Each feature is streamlined and easy to follow. The "Drug Interaction Checker" allows visitors to choose from a list of common drugs, and they can also just type in the name of the drug. Once a drug is selected, the interactions, if any, are shown. Visitors can select to read all of the interactions, or by their severity, such as minor, moderate, or severe. The information given for each interaction is in easy to understand language, devoid of medical jargon, and intended for a general audience.
