VX (C11H26NO2PS), a chemical nerve agent, paralyzes the nervous system. It is more toxic and longer-lived than related nerve agents Tabun and Sarin, which dissipate quickly and have only short-term effects.


VX binds to an enzyme that transmits signals to the nerves and inhibits them. As a result, the nerves become isolated and uncontrollable.


The antidote, atropine, is a toxin itself but counteracts VX by removing it from the enzyme. Atropine is normally injected into the arm or thigh; in the case of gas attacks, however, atropine must be injected directly into the heart. Full body protection and gas masks are essential to avoid exposure in a VX attack.
