Prototype full mu-opioid receptor agonist. Activates mu, kappa, and delta opioid receptors producing analgesia, sedation, and euphoria.
Histamine release with rapid IV injection (hypotension, bronchoconstriction — give slowly). Vomiting and defecation common initial effects. Respiratory depression. Cats: may cause excitation/dysphoria at higher doses. Controlled substance (Schedule II).
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 Morphine across species; consult the rabbit dosing table above for species-specific guidance.

Why a species-specific page? Morphine 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.
