Pain Management in Pet Rats
Pocket Pet · Rattus norvegicus var. domestica · typical adult weight 0.25–0.70 kg
11 cited drugs treat Pain Management in pet rats: Buprenorphine, Butorphanol, Carprofen, Flunixin Meglumine, Ketoprofen, Meloxicam, Meperidine, Methadone, Morphine, Oxymorphone, Tolfenamic acid.
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 pet rats — a reference list, not new species-specific clinical guidance.
