Tecovirimat, sold under the brand name Tpoxx among others,[6] is an antiviral medication with activity against orthopoxviruses such as smallpox and mpox.[4][7][8] In 2018 it became the first antipoxviral drug approved in the United States.[9][10]

The drug works by blocking cellular transmission of the virus, thus preventing the disease.[11] It is an inhibitor of the orthopoxvirus VP37 envelope wrapping protein.[4]

Tecovirimat has been effective in laboratory testing; it has been shown to protect animals from mpox and rabbitpox and causes no serious side effects in humans.[6] Tecovirimat was first used for treatment in December 2018, after a laboratory-acquired vaccinia virus infection.[12]

Two million doses of tecovirimat are stockpiled in the US Strategic National Stockpile should an orthopoxvirus-based bioterror attack occur.[13][14] The U.S. Food and Drug Administration (FDA) considers it to be a first-in-class medication.[15]
