Antivenom is an aid item in Fallout: New Vegas.


Antivenom combines nightstalker blood and radscorpion glands, acting as a cure for poison. It is effective against any poison produced by Nightstalkers, Bark Scorpions, Radscorpions, and Cazadores and fixes the "blur" side effect instantly.

Ulysses mentions that his tribe the Twisted Hairs used a type of antivenom that was stronger, without the need to scavenge glands and blood, called Snakebite Tourniquet.[1]


This item can be crafted with a Survival skill of 40 and the necessary components:

Behind the scenes

There are several variations of the antivenom flask with the game files with differing textures and model names, antivenombark, antivenomcaz and antivenomrad, signifying what type of venom they were meant for. The models for these other variants of antivenom were repurposed for other items. The model for antivenombark is reused for bitter drink and tremble, antivenomcaz for Bleak Venom and datura hide, and antivenomrad for Mother Darkness and Weapon Binding Ritual.


  1. Courier: "Any more recipes.. or histories... you can teach?"
    Ulysses: "Antivenom's helpful around the Mojave with the Bark Scorpions. Even one sting can kill you. Tunneler bite can be just as bad. My tribe, Twisted Hairs, had a better way than Antivenom, if you act fast. Snakebite Tourniquet - cuts off the venom, no need to scavenge glands and blood. Or drink that mess."
