Flu Antivirals

Prescription antiviral medications—such as oseltamivir—work by blocking the influenza virus’s ability to replicate, helping to shorten the duration of your flu symptoms and reduce the risk of complications. Most effective when started within 48 hours of symptom onset, these treatments can ease fever, aches, and congestion, though they may cause side effects like nausea, headache, or diarrhea in some people.
