Abandonment of Human Immunodeficiency Virus Preexposure Prophylaxis Prescriptions at Retail Pharmacies-United States, 2019.

Abstract

We analyzed a national pharmacy database to estimate the annual number of persons who abandoned preexposure prophylaxis (PrEP) prescriptions and assessed associated factors. About 9% of persons prescribed PrEP abandoned prescriptions in 2019; abandonment was associated with sex, age, insurance type, black race/ethnicity, and drug copayment amount.
