Used for Smallpox
Used for Smallpox
Tpoxx (tecovirimat) comes as both an oral capsule and an intravenous (IV) infusion and is approved to treat smallpox in adults and children. This medication is limited in availability because it's reserved for the Strategic National Stockpile. Because of the monkeypox outbreak in the United States, the CDC expanded access to this medication to treat monkeypox in 2022 (although it's not yet FDA-approved for this use). Please note that Tpoxx (tecovirimat) isn't a smallpox vaccine or a monkeypox vaccine, so it can't be used to prevent smallpox or monkeypox.
