Synthetic analog of ACTH (first 24 amino acids). Stimulates adrenal cortex to produce cortisol. Used diagnostically for ACTH stimulation test.
Diagnostic agent — not for chronic therapy. Rare anaphylaxis. Reconstituted solution stable 24 hours refrigerated.
Species-specific contraindications and adverse-reaction reports for rabbits may differ from canine / feline reference data — consult the primary citations listed with each rule.

These are general warnings for Cosyntropin across species; consult the rabbit dosing table above for species-specific guidance. Diagnostic agent — not for chronic therapy. Rare anaphylaxis. Reconstituted solution stable 24 hours refrigerated.
Why a species-specific page? Cosyntropin pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in rabbits — the rules above are the citations specific to this species, not generic recommendations.
