When asked how consumers can save money on their prescriptions (other than caveat emptor importation), I always point out that comparison-shopping between pharmacies can have a huge impact. So kudos to Cigna for their new web site that shows drug prices for 52,000 pharmacies nationwide (both brick-and-mortar and Internet). This site allows Cigna customers to compare the costs of both brand name and generics. (The prices vary based on the kind of insurance held.) The web site will also alert patients when drugs they are shopping for may interact with other medications they’re taking — not only saving out-of-pocket costs, but potential costly hospitalizations and other complications.
