Calyxanide is a cure for Husk Infection.


Calyxanide is a useful drug for managing husk outbreaks among the crew. It is capable of completely curing Husk Infection with a single dose. On fail, only a maximum of 60% infection can be removed without a second dose, and because husk infection is undetectable until it reaches a strength of 20, (40 without the use of a Health Scanner HUD) it could progress beyond a failed injection's strength reduction of 60, requiring the use of either multiple injections of Calyxanide or a second injection of a less potent cure, such as Broad-spectrum Antibiotics.


Like all Medical Items, Calyxanide can be applied through the Health GUI (Default Key H). See this page for more information on usage.

Calyxanide can be loaded into a Syringe Gun, and can also be swung from the hand to apply its effects to whatever it hits. Both of these methods will apply the full effects of the Calyxanide, and since Calyxanide is limb-independent, it may be quicker for a Medical Doctor to use these methods than to open the GUI.

Calyxanide is not used in any crafting recipes.


Calyxanide is a very expensive but potent medicine. It is capable of instantly curing husk infections, but the cost is considerable enough that irresponsible use could burn a hole through a crew's resources very quickly. Broad-spectrum Antibiotics are a much cheaper alternative, and with careful use can be more resource efficient than Calyxanide.

Calyxanide is unable to cure humans once the infection has reached 100% strength, and instead causes them to take damage. It is technically still possible to save a character once they hit 100% Husk Infection, but only via the medical clinic in outposts.

Humans with Husk Genes can still be cured as normal, since the genes keep the infection at 90%.

Calyxanide acts as a poison for fully husk infected humans and natural Husks. It deals damage in accordance to the figures below.
Internal Damage (30)* (Husked Humans).
Internal Damage (40)* (Natural Husks).


  • Although the game hints at the fact that the husk parasite never goes away once it has embedded itself into a host, characters cured with Calyxanide successfully do not regain Husk Infection until it is triggered again by the use of Calyx Extract or another cause of the Husk Infection Affliction.
  • Injection of Calyxanide into a conscious, natural Husk is described as "pissing it off" in the game's XML.
