After being knocked out by the tidal forces of a wormhole and surviving the 's crash landing on a planet in 3189, Commander Jett Reno was interested in a neuroblocker to relieve the pain in her back. ()

On the Dinaali Hospital Ship 4-2 in 2377, The Doctor inquired why Tebbis was not given a neural blocker for his pain. Doctor Voje informed him that Tebbis, who had a low treatment coefficient, had already received his allotment. The Doctor later injected the hospital administrator, Chellick, with a neural blocker combined with chromovirus, to force him to divert enough cytoglobin to save all the chromoviral patients in the hospital.
