Typical IV amiodarone loading (adult): what dose is used?
For adult patients needing an IV loading dose of amiodarone, a common regimen is:
- 150 mg IV given over 10 minutes
- Followed by an infusion of 1 mg/min for 6 hours
- Then an infusion of 0.5 mg/min for the next 18 hours
This totals 150 mg + 36 mg + 9 mg = 195 mg over 24 hours.
How fast do you give the first 150 mg?
The first dose (150 mg) is typically administered over 10 minutes (not as a rapid bolus).
What if loading needs to be repeated or the patient is unstable?
In practice, clinicians may adjust dosing based on response, blood pressure, heart rate, arrhythmia type, and tolerability. The maintenance infusion after the 6-hour period (0.5 mg/min) is part of the standard loading-to-maintenance approach.
What side effects and risks matter during IV loading?
During IV administration, key risks to monitor include hypotension and bradycardia, especially during the initial loading period. Amiodarone can also cause QT prolongation, and it can depress sinus node/AV nodal conduction in susceptible patients.
Is dosing different for different arrhythmias?
IV loading dosing is generally the same framework, but clinical protocols and product labeling can vary by:
- The specific rhythm (e.g., ventricular fibrillation/tachycardia vs atrial fibrillation/flutter)
- Whether the patient is hemodynamically stable
- Local guideline and hospital formulary practices
