From the Guidelines
Carvedilol should be initiated at a dose of 3.125 mg twice daily and titrated up to a target dose of 25-50 mg twice daily, as tolerated, with close monitoring for signs of worsening heart failure, symptomatic hypotension, or excessive bradycardia 1. The dosing guidelines for Carvedilol are based on the patient's tolerance and response to the medication.
- The initial dose is typically 3.125 mg twice daily for heart failure patients.
- The dose can be doubled every 2 weeks as tolerated, up to a maximum of 25 mg twice daily for patients under 85 kg, or 50 mg twice daily for those over 85 kg.
- For hypertension, the maximum dose is generally 25 mg twice daily. Common side effects of Carvedilol include:
- Dizziness
- Fatigue
- Hypotension
- Bradycardia Less common but notable side effects are:
- Weight gain
- Edema
- Worsening of diabetes control Carvedilol should be taken with food to reduce the risk of orthostatic hypotension. It works as a non-selective beta-blocker and alpha-1 blocker, which explains its effects on heart rate, blood pressure, and some of its side effects. The alpha-1 blocking effect contributes to its vasodilating properties, potentially making it more tolerable than some other beta-blockers. Patients should be monitored for worsening heart failure symptoms during dose titration, and the drug should not be abruptly discontinued due to the risk of rebound hypertension or worsening angina 1. The most recent guidelines from 2022 support the use of Carvedilol in the management of heart failure, with a target dose of 25-50 mg twice daily 1, 2.
From the FDA Drug Label
DOSAGE & ADMINISTRATION SECTION Carvedilol Tablet should be taken with food to slow the rate of absorption and reduce the incidence of orthostatic effects.
- 2 Left Ventricular Dysfunction Following Myocardial Infarction DOSAGE MUST BE INDIVIDUALIZED AND MONITORED DURING UP-TITRATION.
- 3 Hypertension DOSAGE MUST BE INDIVIDUALIZED. The recommended starting dose of Carvedilol Tablet is 6.25 mg twice daily. The following adverse events were reported with a frequency of greater than 1% but less than or equal to 3% and more frequently with Carvedilol Tablet: Flu syndrome, cerebrovascular accident, peripheral vascular disorder, hypotonia, depression, gastrointestinal pain, arthritis, and gout Table 1 shows adverse events in U. S. placebo-controlled clinical trials for hypertension that occurred with an incidence of greater than or equal to 1% regardless of causality, and that were more frequent in drug-treated patients than placebo-treated patients.
The dosing guidelines for Carvedilol are as follows:
- The medication should be taken with food to reduce the incidence of orthostatic effects.
- For left ventricular dysfunction following myocardial infarction, the starting dose is 6.25 mg twice daily, which can be increased to 12.5 mg twice daily and then to 25 mg twice daily based on tolerability.
- For hypertension, the starting dose is 6.25 mg twice daily, which can be increased to 12.5 mg twice daily and then to 25 mg twice daily if needed and tolerated.
Potential side effects of Carvedilol include:
- Flu syndrome
- Cerebrovascular accident
- Peripheral vascular disorder
- Hypotonia
- Depression
- Gastrointestinal pain
- Arthritis
- Gout
- Bradycardia
- Postural hypotension
- Peripheral edema
- Dizziness
- Insomnia
- Diarrhea
- Thrombocytopenia
- Hypertriglyceridemia

From the Research
Dosing Guidelines
- The dosing guidelines for Carvedilol vary depending on the indication and patient population 5, 6, 7, 8.
- For essential hypertension, the recommended dose is 6.25-50 mg per day, taken twice daily or as a controlled-release formulation once daily 5.
- For congestive heart failure, the recommended dose is 6.25-50 mg per day, taken twice daily 6.
- For patients with left ventricular systolic dysfunction, rapid up-titration of Carvedilol can be safely performed, with a mean increase of 16 mg/day over a mean time of 1 week 8.
Potential Side Effects
- Common adverse events reported with Carvedilol include headache, dizziness, and fatigue 5, 6, 9.
- The incidence of adverse events is lower with the controlled-release formulation compared to the immediate-release formulation 5.
- Carvedilol is generally well-tolerated, with a low rate of discontinuation due to adverse events 6, 9, 7, 8.
- Patients with renal insufficiency may experience higher plasma concentrations of Carvedilol, but this does not appear to increase the risk of adverse events 9.
Special Considerations
- Patients with renal insufficiency do not require dose adjustments, as the pharmacokinetics of Carvedilol are not significantly altered in this population 9.
- Advanced practice nurses can safely and effectively titrate Carvedilol in patients with heart failure using a remote telephonic protocol 7.
- Rapid up-titration of Carvedilol can be safely performed in hospitalized patients with left ventricular systolic dysfunction, with a low rate of re-admission and long-term mortality 8.
