What it means
Antivirals are medications that fight viral infections by slowing or stopping the virus from multiplying in the body. They are used to treat conditions like influenza, herpes, HIV, hepatitis B and C, and COVID-19. Unlike antibiotics, they do not cure the infection but help control symptoms and reduce complications. Starting antiviral treatment early — often within the first 48 hours of symptoms — is important for best results. Some antivirals are taken as daily long-term therapy. Side effects vary by drug but may include nausea, headache, or fatigue. Never share antiviral medications with others.
