What is the maximum total dose of atropine recommended for adult bradycardia?

For managing adult bradycardia, the maximum total dose of atropine recommended is 3 mg. Atropine works by blocking the effects of the vagus nerve on the heart, increasing heart rate when it's inadequate. The dosing guidelines set by organizations such as the American Heart Association suggest administering atropine in incremental doses of 0.5 mg, with the possibility of repeating this dose every 3-5 minutes until reaching the maximum total of 3 mg. Administering more than this recommended limit does not provide additional benefit and may lead to adverse effects, such as increased heart rate and potential arrhythmias. This dosage aligns with current clinical practices, ensuring both effectiveness and patient safety in the treatment of symptomatic bradycardia.
