Mechanism of action

Alpha-2 adrenergic agonist causing dose-dependent sedation, analgesia, and muscle relaxation. Also activates peripheral alpha-2 receptors causing vasoconstriction and bradycardia.

Side effects & warnings

Profound bradycardia and vomiting (especially cats). Cats more sensitive than dogs. Reversible with atipamezole or yohimbine. Avoid in horses with colic (ileus). 100mg/ml for large animals only.

Species-specific contraindications and adverse-reaction reports for swine may differ from canine / feline reference data — consult the primary citations listed with each rule.

Why a species-specific page? Xylazine pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in swine — the rules above are the citations specific to this species, not generic recommendations.
