Beta-Blocker Conversion: Metoprolol Succinate to Carvedilol

Conversion Rationale

The American College of Cardiology recommends converting metoprolol succinate 100mg/day to carvedilol 12.5mg twice daily initially, then uptitrating to a target of 25mg twice daily as tolerated, based on achieving comparable beta-blockade while following evidence-based target dosing 1
Metoprolol succinate 100mg/day represents approximately 50% of the target dose used in heart failure trials, and carvedilol 12.5mg twice daily represents 50% of the target dose proven effective in clinical trials 1

The American College of Cardiology recommends starting carvedilol 6.25mg twice daily for patients at higher risk, and 12.5mg twice daily for stable patients currently tolerating metoprolol well 1
The target dose is carvedilol 25mg twice daily for most patients, with a maximum dose of 50mg twice daily for patients >85kg with heart failure 1
The American College of Cardiology recommends doubling the carvedilol dose every 1-2 weeks if the preceding dose is well tolerated 1

The American College of Cardiology recommends checking blood pressure and heart rate at each visit during uptitration, and monitoring for symptomatic hypotension, bradycardia, and worsening heart failure symptoms 2

The American College of Cardiology recommends considering starting carvedilol 3.125mg twice daily in women and elderly patients, as they may require only 50% of guideline-recommended doses to achieve optimal outcomes 1, 2
For heart failure patients, the American College of Cardiology recommends ensuring clinical stability before conversion, and notes that the mean carvedilol dose achieved in clinical trials was 37mg/day 1
