Sedation in Leopard Geckos
Reptile · Eublepharis macularius · typical adult weight 0.04–0.10 kg
6 cited drugs treat Sedation in leopard geckos: Alfaxalone, Dexmedetomidine, Ketamine, Meloxicam, Midazolam, 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 leopard geckos — a reference list, not new species-specific clinical guidance.
