Important Information About Paxlovid

Paxlovid (nirmatrelvir/PF-07321332 and ritonavir) is an oral antiviral drug that should be initiated as soon as possible after diagnosis of COVID-19 and within 5 days of symptom onset. Paxlovid is available for patients by prescription only. Prescriptions can be obtained from your health care provider or through the Test to Treat program.

Paxlovid is authorized for the treatment of mild to moderate COVID-19 in adult and pediatric patients age 12 years and older weighing at least 40 kg, with a positive SARS-CoV-2 test, who are at high risk for progressing to severe COVID-19, including hospitalization or death. Please see the Eligibility Screening Checklist for additional details.
