Vaccination, testing, and mitigation efforts such as masking, remain a key part of prevention, even as more drugs become available, says Dr. Topal.
“Early testing is key to making these drugs work,” he says. “It’s always been the Achilles’ heel of these antiviral drugs that most people don’t get tested—or they don’t have access to testing.”
He encourages taking a test even if you think you only have a cold or allergies—and if you can get one. “Home testing is a huge part of the way to really ‘operationalize’ these medications,” he says, adding that while home tests may not be as highly sensitive as the laboratory-based polymerase chain reaction (PCR) tests, they are still very helpful in making a diagnosis.
Dr. Topal says people also should remember that Paxlovid, even with its high efficacy, is not perfect, and even if it were, viruses can mutate and develop resistance to antiviral medications. “Will some people still be hospitalized? Yes—no medication is perfect,” he says. “But for many high-risk patients, this medication can really reduce that risk.”
If you are experiencing symptoms of COVID and think you are eligible for a treatment, you can visit the government Test-to-Treat Locater. You can use the site to search for the places near you where you can fill a COVID prescription, or identify sites that provide testing, medical care, and COVID medications.
If finances are an issue, a U.S. Government Patient Assistance Program operated by Pfizer is making Paxlovid available at no cost through Dec. 31, 2024 to eligible individuals covered under federal programs such as Medicare and Medicaid, and to those who are uninsured.
