Paxlovid is an oral antiviral medication that prevents high-risk patients from becoming too sick and requiring hospitalization. The drug is available with a prescription from a health care provider or from a pharmacist, and should be taken within five days of developing symptoms. The dosage is three pills, twice a day, for five days, or a total of 30 pills. The tablet has shown the capacity to reduce the risk of hospitalization or death for high-risk adults with COVID-19 by 89%. 35 Companies to Produce Generic Version of COVID Pill that Helps Prevent Hospitalization and Death Earlier this month, the FDA authorized pharmacists across the United States to prescribe Pfizer's antiviral treatment pill to eligible patients. Individuals who test positive for COVID and want to determine their eligibility to take Paxlovid can bring a list of their current medications and health records detailing kidney or liver problems to their pharmacist for review. Patients with reduced kidney function may require a lower dose of Paxlovid, per the FDA. The FDA first granted Paxlovid emergency use authorization in December 2021 for use in patients age 12 or older who are at a high risk of developing severe COVID-19 due to underlying medical conditions.
