Med-X

Med-X is a chem that appears in Fallout 3, Fallout: New Vegas, Fallout 4, Fallout 76, and Fallout: The Board Game.

Background
Med-X is a potent opiate analgesic that binds to opioid receptors in the brain and central nervous system, reducing the perception of pain as well as the emotional response to pain. Essentially, it is a painkiller delivered by a hypodermic needle. According to the Powder Ganger, Boxcars, five hits of Med-X is enough for a man to "put himself out of his misery," though he also claims that if the Courier wanted him dead, fifteen doses of Med-X would make him overdose. With enough Medicine skill when talking with Joana, it is revealed that Med-X addiction includes such symptoms as contracted pupils and involuntary spasms.
