HealthDay News – Excess expenditures associated with using brand-name medications when lower cost generics were available for the same indication were evaluated in a cross-sectional study published in JAMA Internal Medicine.
Michael Johansen, MD, family medicine physician with the Ohio State University Wexner Medical Center in Columbus, and colleagues reviewed self-reported prescription drug use by 107,132 Americans who were part of the 2010 to 2012 Medical Expenditure Panel Survey.
The study authors found that $760 billion was spent on prescription drugs during the study. Nearly 10% of all prescription drug expenses involved brand-name drug overuse. Out-of-pocket expenses totaled $175 billion during the study. Brand-name drug overuse accounted for 14% of these costs.
“We observed an estimated potential savings of $73 billion overall and nearly $25 billion in out-of-pocket expenses throughout the three years of the study,” Johansen said in a university news release.
