A Pennsylvania pharmacist testified that only generic drug makers are benefiting from large price increases for generic medications. The pharmacist cited drug shortages, industry consolidation, and fewer manufacturers as reasons for the price hikes, with some generics increasing in price by as much as 8,000%. A government investigation into the sudden price increases was announced. An analysis found that more than 12,000 generic drugs have seen dramatic price rises in the last 18 months, hardest hit being patients paying out of pocket for prescriptions.
