Sedation in Eastern Box Turtles
Reptile · Terrapene carolina · typical adult weight 0.30–0.60 kg
7 cited drugs treat Sedation in eastern box turtles: Alfaxalone, Butorphanol, Dexmedetomidine, Ketamine, Midazolam, Morphine, Tiletamine-Zolazepam.
Pharmacologic sedation for diagnostic procedures, minor surgical interventions, and pre-anaesthetic premedi-cation. α2 agonists (dexmedetomidine, medetomidine), phenothiazines (acepromazine), and benzodiazepines (midazolam) form the backbone of veterinary protocols.
The overview above describes Sedation across species; the citations below are the ExoticRx dose rules scoped to eastern box turtles — a reference list, not new species-specific clinical guidance.
