Iodine’s website provides not only basic information about each drug — its purpose, how it works, side effects and warnings — but also a section with the upsides and downsides of taking a drug, price and co-pays, alternative drugs and interactive tools. They enable a user to see how people rate their experience with a drug based on survey questions. Then, users can see in greater detail how the drug rated for people like themselves, by clicking by gender and age group. The results are presented on a grid with nine squares, with the upper right-hand square being ideal — reflecting the highest ratings for “works well” and “hassle free.” Seventy percent of Americans take at least one prescription drug and 50 percent take two or more. Yet studies show that half or more of people with chronic diseases do not take their drugs as prescribed. Lack of adherence to drug regimens is estimated to cause 125,000 deaths a year and cost between $100 billion and $289 billion annually.
