PLANO, Texas — Retail co-pays for drugs are on the rise across all drug types, according to a new study by the Pharmacy Benefit Management Institute.
The study, based on a survey of 424 U.S. employers representing about 3.7 million members, found that retail co-pays increased 10% for generics, 13% for branded drugs and 26% for specialty drugs. Meanwhile, there was an increase in use of multitier designs, which now represent 92% of plan sponsors, while adoption of medication therapy management for commercial populations was "minimal."
