Hydra is a consumable item in Fallout: New Vegas.


Hydra is a drug developed from antivenom. Due to the Legion's disapproval of using modern medicine, some Legionaries attempted to develop a different means to help them heal damaged limbs. To do that, they combined cave fungus with antivenom, developing hydra - a curative agent which both anesthetizes and restores crippled limbs over time. Despite its origins in the Legion, this drug has since seen extensive use throughout the entire Mojave Wasteland, including NCR field hospitals.


Hydra appears as a "Supa Yum"-brand soda bottle with three sealed glass vials of liquid taped around its middle, each one with a thin rubber tube feeding their contents up to the mouth of the bottle.

Like a doctor's bag, hydra is used to restore health to crippled limbs, making it especially useful in Hardcore mode where stimpaks or sleeping in a bed one doesn't own (from having rented or being given the room) won't heal these injuries. It has the advantage over doctor's bags in that it is weightless and it will continue to slowly heal the crippled wounds over 60 seconds. In a tough fight, where one might receive crippling wounds several times, a single dose of hydra can heal them as they are received. Hydra also benefits from the Chemist and Day Tripper perks.

The downside is that hydra carries a 10% risk of developing an addiction. If this happens one will suffer a negative hit to statistics (-3 Endurance) unless more hydra is used, Fixer is used, or a doctor is seen.

Excessive use causes dilated eyes, an increased heart rate and blood pressure and massive sweating.[1]

Hydra (1)



  • Prior to patch the recipe required five cave fungi. After the patch, the cave fungus drop rate was significantly increased, especially on Legionary scouts, and the requirement was changed to only one cave fungus.
  • Gametitle-FNV HH Many caverns in the Zion Canyon are abundant with cave fungi.
  • Gametitle-FNV LR Tunnelers frequently drop two cave fungi upon death, making them a reliable source of cave fungus next to the Zion Canyon that does not risk Legion Infamy.

Behind the scenesEdit

This chem is named after the Hydra in Greek mythology, which regrew two heads in place of every one head severed.
