Antiviral medications are drugs that specifically target viruses by inhibiting their replication or spread within the body. Unlike antibiotics, which fight bacteria, antivirals are used to treat infections caused by viruses such as influenza, herpes, HIV, hepatitis, and COVID-19. Early treatment with antivirals can significantly reduce the severity and duration of many viral infections.

Common Types of Anti-Viral Medications
Oseltamivir (Tamiflu)
An influenza antiviral most effective when started within 48 hours of symptom onset. Reduces the duration and severity of flu symptoms and can be used for flu prevention in high-risk individuals.
Acyclovir / Valacyclovir
Used for herpes simplex virus (cold sores, genital herpes) and varicella-zoster virus (shingles, chickenpox). Valacyclovir (Valtrex) is better absorbed and requires less frequent dosing than acyclovir.
Antiretrovirals (HIV)
Combination antiretroviral therapy (ART) suppresses HIV viral load to undetectable levels, allowing people with HIV to live healthy lives and preventing transmission. Includes NRTIs, NNRTIs, protease inhibitors, and integrase inhibitors.
Hepatitis C Antivirals
Direct-acting antivirals (DAAs) like sofosbuvir/ledipasvir (Harvoni) and glecaprevir/pibrentasvir (Mavyret) can cure hepatitis C in most patients with an 8–12 week course of treatment.
Nirmatrelvir/Ritonavir (Paxlovid)
An oral COVID-19 antiviral authorized for high-risk adults and children over 12. Most effective when started within 5 days of symptom onset to prevent severe illness.
Remdesivir (Veklury)
An IV antiviral used in hospitalized COVID-19 patients. Originally developed for Ebola, it inhibits viral RNA polymerase and has been shown to reduce recovery time in certain COVID-19 patients.
