Benzocyatizine is a medication used to treat Trill joined with symbionts that suffer from low isoboramine levels. In 2371, Renhol and other Trill Symbiosis Commission doctors gave Jadzia Dax benzocyatizine when her isoboramine levels were low. (DS9 episode: "Equilibrium") When a joined Trill is given an analgesic, such as terakine, it would need to be metered with benzocyatizine. When Kell Perim was injured in 2379, Beverly Crusher did not need to use benzocyatizine as Kell was not joined. (TNG novel: A Time to Sow)
