Potent synthetic glucocorticoid. Suppresses inflammation, immune responses, and allergic reactions. 25-30x potency of cortisol.
Immunosuppressive. PU/PD, polyphagia. Avoid in active infections without antibiotic coverage. Prolonged use causes iatrogenic hyperadrenocorticism. Avoid in reptiles if possible (severe immunosuppression).
Species-specific contraindications and adverse-reaction reports for cat may differ from canine / feline reference data — consult the primary citations listed with each rule.
Why a species-specific page? Dexamethasone pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in cat — the rules above are the citations specific to this species, not generic recommendations.
