Tachycardia, ileus, urinary retention. Increases myocardial oxygen demand. Rabbits have high atropinase activity — may need higher/more frequent doses or use glycopyrrolate instead.
Species-specific contraindications and adverse-reaction reports for pet rats may differ from canine / feline reference data — consult the primary citations listed with each rule.
