noun

phar·​ma·​co·​vig·​i·​lance ˌfär-mə-kō-ˈvi-jə-lən(t)s 

: the monitoring, evaluation, and prevention of adverse effects associated with the administration of medicines

With generic drugs now accounting for more than 75% of U.S. prescriptions, imposing even a minimal fee on each prescription would provide the revenue for an important investment in pharmacovigilance for late-arising safety issues.
