COVID -19 Provider Information
COVID Treatment Update:
Last December, the FDA issued an emergency use authorization for Paxlovid (nirmatrelvir/ritonavir; Pfizer) and Lagevrio (molnupiravir; Merck) for treatment of mild-to-moderate COVID-19 infections.
Both therapies are now widely available in community pharmacies. And while infection and hospitalization rates have declined, higher-risk patients are still getting sick and requiring hospitalization. Early treatment with Paxlovid and other treatments can make a difference.
