With healthcare costs continuing to rise, generic drugs are looking more attractive than ever. The prospect of getting the same drug at a lower cost is tempting to anyone with a large drug bill — patient or insurer alike. The savings to insurers and individuals are massive: prices can drop by 90% or more, almost overnight. In 2012, Plavix and Seroquel, two other blockbusters, lost patent protection too — with just two drugs, it was estimated there would be $10 billion in health care savings created. A “patent cliff” that existed several years ago was expected to shrivel about $255 billion in worldwide patented drug sales over the following five years.If you’re taking a prescription drug and not already on a generic version, you may be in the future.
