Ceftriaxone
Ceftriaxone: Antibiotic with no adrenaline side effect; immunity does not stack, only duration. In-game item, not medical advice.
Use, trade-offs and mechanics
Ceftriaxone is a non-craftable antibiotic fluid used against infection and sepsis in the game. Its main treatment mechanism is timed immunity: every injected milliliter adds eleven and a quarter seconds to the immunity timer. While that timer is active the reference adds seventy immunity. A larger amount extends duration instead of multiplying the immunity increase.
The injection also adds eight-tenths of a point of pain to the treated limb per milliliter. Unlike many other pain sources, the entry explicitly says this does not provide adrenaline. Pain, immunity and adrenaline should therefore not be treated as one linked effect for this liquid. The health panel interaction uses a ceftriaxone syringe or another injectable container.
Drinking ceftriaxone has no treatment effect in the community entry. A container's ability to be consumed does not mean that route activates its useful properties. That makes identification and the selected interaction especially important when a player is moving liquids between containers.
The fluid appears in syringes and mini-barrels, and its Antiseptic quality can be used in antivenom, L.R.D. Serum and sterilized dressing recipes. It is thus a possible crafting resource even though the fluid itself cannot be crafted. Compare that material use with current infection needs. The distinct antiserum entry provides disinfection and direct sepsis reduction in addition to immunity; the two antibiotics share a timer rule but do not supply exactly the same treatment package.
