Brincidofovir, sold under the brand name Tembexa, is an antiviral drug used to treat smallpox. Brincidofovir is a prodrug of cidofovir.[3] Conjugated to a lipid, the compound is designed to release cidofovir intracellularly, allowing for higher intracellular and lower plasma concentrations of cidofovir, effectively increasing its activity against dsDNA viruses, as well as oral bioavailability.[4]

The most common side effects include diarrhea, nausea, vomiting, and abdominal pain.[2] It carries an FDA-mandated black box warning of an increased risk of death with extended use.[5][6] Brincidofovir was approved for medical use in the United States in June 2021.
