Antibiotics are a medical loot item found in Stranded Deep. Antibiotics can be found hidden inside cabinets contained within shipwrecks, and can be distinguished from vitamins by their blue labels and cap. Once acquired, they can be used to cure the player of the poisoning effect. As of v0.03, the antibiotics hold a limited number of uses and can be destroyed upon total consumption.
Like other loot items, despite spending a considerable amount of time inside underwater shipwrecks, the antibiotics manage to remain almost completely well-preserved, to the point where the labels appear readable and consuming the pills will not bring any other minor side effects to the player.
