Antiviral Therapy (Influenza, COVID-19)

Antivirals slow how quickly the influenza or COVID-19 virus copies itself, giving your immune system room to recover and helping you feel better sooner. Because they target active viral replication, the benefit is greatest when treatment begins early in the illness.

We confirm your diagnosis through COVID-19 and respiratory pathogen testing when appropriate, then review your symptoms, timeline, and any chronic conditions. We also check your current medications carefully, since drugs like Paxlovid can interact with others — part of a thorough medication reconciliation before prescribing.

Reach out as soon as symptoms begin so we can act within the early treatment window. Have a current list of all your medications and supplements ready, since this helps us screen for interactions and choose the safest option.

Let us know about any chronic conditions — such as asthma, kidney concerns, or a weakened immune system — and whether you are pregnant or breastfeeding. These details guide which antiviral is right for you and at what dose.

Most people complete a short course over several days and begin to improve, though it's normal for some symptoms to linger as you heal. Take the full course exactly as prescribed, even once you feel better, and stay well hydrated and rested.

We'll check in on your progress and watch for any warning signs that need closer attention. If your symptoms worsen or you develop trouble breathing, we coordinate prompt follow-up and, when needed, arrange care with specialists including Cedars-Sinai Medical Center.
