Analeptic

An analeptic (or analeptic compound) was a drug that counteracts the effects of radiation.

In 2373, Neelix took some analeptic compounds with him on a mission to a Nezu colony planet being bombarded by asteroids. 

The Malon use analeptic compounds to ameliorate the cellular degradation caused by theta radiation exposure. In 2375, Fesek treated B'Elanna Torres with analeptic compounds during a mission to prevent a malfunctioning Malon freighter from exploding. 

When the USS Voyager was split into different timeframes in 2377 by a chronokinetic surge, Tom Paris ordered that analeptics be given to crew members suffering from radiation poisoning once the netrazine ran out.
