Characteristics of Copayment Offsets for Prescription Drugs in the United States

Aditi P. Sen et al.

Summary: This study analyzed the use of offsets in retail pharmacy transactions in the United States from 2017 to 2019, finding that approximately half of all offsets involved pharmacy-PBM contractual arrangements, while the other half were offered by manufacturers. All offsets significantly reduced patients' out-of-pocket costs, were concentrated among a few drugs, and were generally not more generous among individuals in counties with lower income or larger Black or uninsured populations.

Factors Associated With Manufacturer Drug Coupon Use at US Pharmacies

So-Yeon Kang et al.

Summary: This cohort study analyzed transactional pharmacy claims from retail US pharmacies between October 2017 and September 2019, finding that higher mean per-patient total cost within a drug class was significantly associated with the likelihood of manufacturer drug coupon use, but not patient out-of-pocket cost. Manufacturers were more likely to offer coupons for expensive later-in-class-entrant products facing within-class competition where coupon use was prevalent.
