Key points

  • CDC recommends antiviral medicines for influenza, distinct from antibiotics used for bacterial infections.
  • HIV is usually treated with a combination of medicines from more than one antiretroviral class.
  • Herpesvirus, hepatitis and HIV medicines each target a different virus.

Medicines for herpesvirus infections

Valtrex contains valaciclovir, Zovirax and Aciclovir Tablets contain aciclovir, and Famvir contains famciclovir, treating herpes zoster, herpes simplex infections and varicella.

Medicines for influenza and COVID-19

Tamiflu contains oseltamivir for influenza A and B, covered by CDC in Treating Flu with Antiviral Drugs. Amantadine Tablets also treats influenza A, as well as Parkinson’s disease, and Movfor contains molnupiravir for COVID-19.

Medicines for HIV-1

Biktarvy combines bictegravir with emtricitabine and tenofovir alafenamide, and Trustiva combines tenofovir disoproxil with efavirenz and emtricitabine. Sustiva contains efavirenz alone, Kaletra combines lopinavir with ritonavir, and Zerit contains stavudine. Tenvir-EM pairs tenofovir disoproxil with emtricitabine, also used for pre-exposure prophylaxis; FDA describes this approach in HIV and AIDS: Medicines to Help You.

Medicines for viral hepatitis

Tenvir and Baraclude contain tenofovir disoproxil and entecavir for chronic hepatitis B. Velpanat pairs sofosbuvir with velpatasvir, Harvoni pairs ledipasvir with sofosbuvir, and Copegus contains ribavirin, all for chronic hepatitis C.

Starlix, Capoten and Atacand also appear in this group, used for type 2 diabetes and high blood pressure. Medex Tablets prevents blood clots, and Chloroquine Tablets treats malaria and rheumatoid arthritis; none of these five treats a viral infection.
