What maximum dose of Atropine is allowed for treating unstable bradycardia in adults?

The maximum dose of Atropine for treating unstable bradycardia in adults is 3 mg. This standard is in line with established guidelines and protocols for emergency medical situations. Atropine works by increasing the heart rate by inhibiting the vagus nerve's influence on the heart, making it crucial in situations where bradycardia poses an immediate risk to the patient.

In practice, a typical treatment protocol allows for an initial dose of 0.5 mg of Atropine to be administered intravenously, which can be repeated every 3-5 minutes up to the maximum total dose of 3 mg. Administering more than this maximum dose does not provide additional therapeutic benefit and increases the risk of potential side effects. Thus, adhering to this maximum dose is critical for safe and effective patient care in the context of unstable bradycardia.
