Med-X is a chem in Fallout 3.


Med-X is a highly potent painkiller which, when injected, makes the user impervious to pain to the degree that Damage Resistance is increased by 25%. This will last for 6 minutes, or 12 minutes with the Chemist perk.

Besides providing the benefits of regular armor, the prototype medic power armor will automatically dispense Med-X every 2.5 hours (game time) if the player character's health drops below 33% or if a limb's health drops below 25%. While being administered through the power armor, an addiction to Med-X will not develop.



  • In the G.E.C.K, the Editor ID is still displayed as "morphine."
  • In the G.E.C.K., it lists the effect as "ChemIncDamResistPsycho". This would have been psycho's effect at first, mimicking the psycho from Fallout, Fallout 2, and Fallout Tactics.
  • The effects of addiction are listed as "Morphine Addiction".

Behind the scenes

Originally, Med-X was named "morphine" in the game. However, on July 4, 2008, Fallout 3 was refused classification by the OFLC in Australia, thus making the game illegal for sale in the country due to the "realistic visual representations of drugs and their delivery method [bringing] the 'science-fiction' drugs in line with 'real-world' drugs." On September 9, 2008 Bethesda Softworks's vice president of PR and marketing, Pete Hines, described the idea of the Australian version of Fallout 3 as a misconception, and said all versions of Fallout 3 will not include real-world drug references. However, the name "morphine" is still used in the Japanese and Czech versions of the game.
