This calculator performs arithmetic only on the sourced dosing field shown for each result — it does not verify the field's accuracy, does not select which field to use for a patient, and does not replace a veterinarian's order. Not for clinical use. Confirm every result against the primary source before dispensing.

Precautions4
Not effective for bradycardia in puppies <14 days or kittens <11 days old; caution combining with alpha-2 agonists (dexmedetomidine) — controversial, may worsen hypertension/arrhythmias; rabbits often have endogenous atropinesterase — use glycopyrrolate instead

Atropine response test (differentiating vagal vs. non-vagal bradyarrhythmias): give 0.04 mg/kg IV, wait 15 min, recheck ECG — persistent sinus tachycardia >140 bpm expected if vagally mediated.

In organophosphate/carbamate toxicity, dose to effect (drying of secretions) rather than a fixed dose — repeat as needed since this reflects a large functional antidote reserve.

Do NOT rely on atropine to reverse bradycardia in very young neonates — it is reportedly ineffective in puppies <14 days/kittens <11 days.
