Pain Management in Red-eared Sliders
Reptile · Trachemys scripta elegans · typical adult weight 0.20–2.20 kg
10 cited drugs treat Pain Management in red-eared sliders: Bupivacaine, Fentanyl, Hydromorphone, Lidocaine, Meloxicam, Meperidine, Methadone, Morphine, Tapentadol, Tramadol.
Multimodal analgesia spanning NSAIDs, opioids, local anaesthetics, NMDA antagonists (ketamine), α2 agonists, and adjuncts. Species safety matters: NSAIDs are unsafe in some reptiles, opioid receptor distributions differ in birds, and rabbits tolerate buprenorphine particularly well.
The overview above describes Pain Management across species; the citations below are the ExoticRx dose rules scoped to red-eared sliders — a reference list, not new species-specific clinical guidance.
