The original manufacturer of azelastine‒fluticasone (AZ‒FL) prevented generic availability until 2020 via patent enforcement. Following generic availability of AZ‒FL, Medicare utilization increased and spending decreased. Retail prices for generic AZ‒FL remain high due to markup by manufacturers and pharmacies.
