Version July 2025
Dosage guidance:
Dosing: Individualize dosage for each patient; monitor patients closely during initiation and upwards titration of dose; reduce dose for hypotension or bradycardia. Pharmacokinetic data suggest a faster carvedilol elimination in young pediatric patients (<3.5 years of age), which may require more frequent dosing (3 times daily) and a higher target dose per kg (Ref).
Heart failure: Note: Prior to initiating therapy, other congestive heart failure medications should be stabilized and fluid retention minimized.
Infants, Children, and Adolescents: Limited data available, reported regimens and efficacy results variable; optimal dose not established:
Immediate release: Oral: Initial: 0.04 to 0.075 mg/kg/dose twice daily titrate as tolerated; may increase dose by 50% to 100% every 2 weeks; maximum daily dose: 1 mg/kg/day up to 50 mg/day (Ref). Dosing based on 2 retrospective analyses and 1 prospective, randomized-controlled study (n=110, age range: 3 months to 19 years) which showed improvement in left ventricular function and heart failure symptoms. However, a large, multicenter, double-blind, placebo-controlled, dose-finding trial was not able to show statistical difference in treatment effect compared to placebo; of note, a subset analysis suggested ventricular morphology may play a role in the efficacy of carvedilol in the treatment of heart failure (Ref).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
Mild to severe impairment: There are no dosage adjustments provided in the manufacturer's labeling; in adults, no adjustment is necessary (Ref).
Hemodialysis: Hemodialysis does not appear to significantly clear carvedilol.
Mild to moderate impairment: There are no dosage adjustments provided in the manufacturer's labeling.
Severe impairment: There are no dosage adjustments provided in the manufacturer's labeling. In adults, use is contraindicated.
(For additional information see "Carvedilol: Drug information")
Angina, chronic stable (off-label use):
Note: For vasospastic angina, beta-blockers are not recommended; calcium channel blockers and nitrates are preferred. For nonvasospastic angina, titrate beta-blocker to relieve angina or equivalent symptoms (Ref).
Immediate release: Oral: Initial: 12.5 mg twice daily; increase dose as tolerated to desired effect; usual dosage range: 25 to 50 mg twice daily (Ref).
Atrial fibrillation/flutter, maintenance of ventricular rate control (off-label use):
Note: Initiate cautiously in patients with concomitant heart failure. Avoid initiating or up-titrating therapy in patients with decompensated heart failure; for unstable patients, electrical cardioversion is preferred (Ref).
Immediate release: Oral: Initial: 3.125 mg twice daily; increase dose as tolerated to achieve ventricular rate control up to 25 mg twice daily (Ref).
Heart failure with reduced ejection fraction :
Note: Initiate only in stable, euvolemic patients. In hospitalized patients, volume status should be optimized and IV diuretics, IV vasodilators, and IV inotropic agents successfully discontinued prior to initiating therapy. Use caution when initiating in patients with New York Heart Association class IV symptoms or recent heart failure exacerbation (particularly if inotropes were required during hospital course) (Ref).
Immediate release: Oral: Initial: 3.125 mg twice daily; up-titrate gradually (eg, doubling the dose every ≥ 1 to 2 weeks) to the target dose while monitoring for signs and symptoms of heart failure (Ref).
Target dose:
≤85 kg: 25 mg twice daily.
>85 kg: 50 mg twice daily.
Extended release: Oral: Initial: 10 mg once daily; up-titrate gradually (eg, doubling the dose every 1 to 2 weeks) to the target dose of 80 mg once daily while monitoring for signs and symptoms of heart failure (Ref).
Hypertension (alternative agent):
Note: Not recommended in the absence of specific comorbidities (eg, arrhythmia ischemic heart disease, heart failure with reduced ejection fraction) (Ref).
Immediate release: Oral: Initial: 6.25 mg twice daily; titrate in ≥1-week intervals as needed based on patient response; usual dosage range: 6.25 to 25 mg twice daily; maximum dose: 50 mg/day (Ref).
Extended release: Oral: Initial: 20 mg once daily; titrate in ≥1-week intervals as needed based on patient response; usual dosage range: 20 to 80 mg/day; maximum dose: 80 mg/day (Ref).
Myocardial infarction, early treatment and secondary prevention (alternative agent) (off-label use):
Note: An oral beta-blocker is recommended within the first 24 hours for most patients. Patients who do not receive a beta-blocker within 24 hours of myocardial infarction due to contraindications should be reevaluated for secondary prevention at a later date (Ref).
Immediate release: Oral: Initial: 3.125 to 6.25 mg twice daily; titrate dose based on heart rate and blood pressure as tolerated up to 25 mg twice daily (Ref). The optimal duration of therapy is unknown; reassess need for long-term beta-blocker use (>1 year) if no other primary indication exists (eg, angina, arrhythmia, heart failure with reduced ejection fraction, or hypertension) (Ref).
Nonsustained ventricular tachycardia or ventricular premature beats, symptomatic (off-label use) :
Immediate release: Oral: Initial: 3.125 mg twice daily; titrate as needed based on response and tolerability up to 25 mg twice daily (Ref).
Variceal hemorrhage prophylaxis, primary (alternative agent) (off-label use):
Immediate release: Oral: Initial: 3.125 mg twice daily or 6.25 mg once daily; titrate according to resting heart rate (target 55 to 60 beats per minute) while maintaining blood pressure (eg, systolic blood pressure ≥90 mm Hg) to a maximum dose of 6.25 mg twice daily (Ref).

PIRRT (eg, sustained, low-efficiency diafiltration): No dosage adjustment necessary (Ref).
Mild to moderate impairment: There are no dosage adjustments provided in the manufacturer's labeling; dose conservatively and interrupt therapy in the setting of hypotension (eg, mean arterial pressure [MAP] <65 mm Hg), acute kidney injury, or hyponatremia (Ref).
Severe impairment: Use is contraindicated per manufacturer; however, experts will use if indicated (eg, for variceal hemorrhage prophylaxis); dose conservatively and interrupt therapy in the setting of hypotension (eg, MAP <65 mm Hg), acute kidney injury, or hyponatremia (Ref).
Beta-blockers may cause first-degree atrioventricular (AV) block, second-degree AV block, or complete atrioventricular block (Ref). At maintenance dosing, second- or third-degree AV block are less likely (Ref). Beta-blocking agents with intrinsic sympathomimetic activity (eg, pindolol) may cause fewer AV conduction abnormalities than those without intrinsic sympathomimetic activity (eg, carvedilol) due to their partial agonist effects (Ref). In most cases (up to 72%), AV block associated with a beta-blocker will resolve upon discontinuation; however, there are reported cases of recurrent AV block and nearly 50% of patients with more severe AV block may require a permanent pacemaker (Ref).
Mechanism: Dose-related; related to the pharmacologic action. Blockade of cardiac beta-1 adrenergic receptors results in slowed conduction and prolongation of the refractory period of the AV node. Slowing of AV conduction can lead to AV block (Ref).
Onset: Varied; one study included patients who were on a beta-blocker for more than 1 month (Ref); however, other studies noted prolongation of the PR interval or AV nodal refractory period occurring anywhere from 1 dose to several days following treatment initiation (Ref).
Risk factors:
• Impaired AV node conduction or sinus node function (Ref)
• Concurrent use of other agents that impair AV nodal conduction (eg, nondihydropyridine calcium channel blockers, digoxin, ivabradine, select antiarrhythmic agents) (Ref)
• Older patients (Ref)
Nonselective beta-blockers (eg, carvedilol) have a higher risk of bronchospasm compared to cardioselective beta-blockers (Ref) and may lead to drug discontinuation in patients with chronic obstructive pulmonary diseases (COPD) or asthma (Ref). One study showed that patients with asthma and heart failure tolerated carvedilol poorly (Ref). Concurrent use of inhaled bronchodilators and/or corticosteroids are protective against beta-blocker–induced bronchospasm in patients with COPD or asthma (Ref). Bronchospasm is reversible upon discontinuation (Ref).
Mechanism: Dose-related; related to pharmacologic action. Beta-blocking agents can lead to airway smooth muscle constriction by antagonism of beta-2 receptors (Ref).
Onset: Varied; changes in peak expiratory flow rates have occurred after 1 dose. Discontinuation due to carvedilol-induced bronchospasm varied from 5 days to 6 months (Ref).
Risk factors:
• Reactive airway disease (asthma) (Ref)
Beta-blockers may cause CNS effects such as fatigue, sleep disorder, insomnia, and vivid dreams (Ref). Memory impairment has been reported with carvedilol; however, newer data suggest it may be helpful for patients with Alzheimer disease (Ref). Sexual disorders may occur; however, patients who require beta-blocker therapy have risk factors for erectile dysfunction (eg, coronary artery disease, heart failure) (Ref). Lipophilic beta-blockers (such as carvedilol, which is highly lipophilic) penetrate the blood-brain barrier to a greater extent than hydrophilic beta-blockers, possibly leading to a greater incidence of CNS effects; however, other studies have refuted this theory (Ref). CNS effects generally resolve with dose reduction or discontinuation (Ref).
Mechanism: Dose-related; exact mechanism is not fully understood. Proposed mechanisms include presence of beta receptors in the brain, affinity (and in some instances, inhibition) of beta-blocking agents towards serotonin (5-HT) receptors in the brain (affecting mood and sleep), and beta-blocker–induced decreases in central sympathetic output (Ref). Beta-1 blockade may also impact sleep by blocking sympathetic signaling to the pineal gland, resulting in suppression of nighttime levels of melatonin (Ref). Beta-blockers may cause erectile dysfunction through decreased sympathetic nervous system output and subsequent decreases in luteinizing hormone secretion and testosterone stimulation (Ref).
Onset: Intermediate; CNS effects often occur within the first few weeks of treatment (Ref).
Risk factors:
• Higher starting doses (Ref)
• Older patients (Ref)
Beta-blockers may worsen, prolong, or cause hypoglycemia (Ref). Additionally, beta-blockers may mask symptoms of hypoglycemia (tremor, irritability, palpitations), making diaphoresis the only symptom unaffected by beta-blockers (Ref). It is unclear if nonselective or selective beta-blockers are more likely to cause hypoglycemia, as data are conflicting (Ref).
Mechanism: Dose-related; related to the pharmacologic action. Beta-blockers inhibit hepatic gluconeogenesis and glycogenolysis (Ref). Beta-blockers also reduce activation of the sympathetic nervous system, therefore masking hypoglycemic symptoms that are catecholamine-mediated (Ref).
Onset: Varied; hypoglycemia (<70 mg/dL) was reported significantly more after 24 hours of carvedilol use compared to patients not on beta-blockers (Ref). In another study, episodes of severe hypoglycemia (<50 mg/dL) were reported over the course of 4 years (Ref).
Risk factors:
• Insulin-dependent diabetes (Ref)
• Type 2 diabetes mellitus (Ref)
• Patients who are hospitalized and not requiring basal insulin (Ref)
Beta-blocker therapy should not be withdrawn abruptly but gradually tapered to avoid acute tachycardia, hypertension, and/or ischemia in patients with underlying cardiovascular disease (Ref). Some studies have found an increase in propensity-adjusted mortality and cardiovascular events; however, one study did not find changes in infarct size and left ventricular function when beta-blocker was abruptly withdrawn in patients with myocardial infarction (Ref).
Mechanism: Dose-dependent; related to the pharmacologic action. Beta blockade causes upregulation of beta receptors, enhanced receptor sensitivity, and decreased sympathetic nervous system response. Abrupt withdrawal leads to a transient sympathetic hyper-response (Ref). Another proposed mechanism involves increased platelet aggregability to epinephrine and thrombin (Ref).
Onset: Rapid/varied and transient; increases in heart rate and blood pressure appear 24 hours after abrupt withdrawal, peak after 48 hours, and subside after 7 days (Ref). In other nonselective beta-blockers (propranolol), anginal symptoms are reported to begin 12 to 24 hours after discontinuation. Development of adverse reactions is also reported to occur 1 to 21 days after withdrawal (Ref).
Risk factors:
• Abrupt withdrawal in chronic users (Lederballe Pederson 1979)
• Past medical history of coronary artery disease (including chronic stable angina) (Ref)
• Past medical history of hypertension (Ref)

Canadian labeling: Additional contraindications (not in US labeling): Severe hypotension; primary obstructive valvular heart disease; mental incapacity (eg, severe Alzheimer disease, alcoholism, drug abuse), unless closely supervised by an appropriate caregiver.
Concerns related to adverse effects:
• Anaphylactic reactions: Use caution with history of severe anaphylaxis to allergens; patients taking beta-blockers may become more sensitive to repeated challenges. Treatment of anaphylaxis (eg, epinephrine) in patients taking beta-blockers may be ineffective or promote undesirable effects.
• Bradycardia: May occur; reduce dosage if heart rate drops to <55 beats/minute.
• Floppy iris syndrome: Intraoperative floppy iris syndrome has been observed in cataract surgery patients who were on or were previously treated with alpha1-blockers; there appears to be no benefit in discontinuing alpha-blocker therapy prior to surgery. Instruct patients to inform ophthalmologist of carvedilol use when considering eye surgery.
• Hypotension/syncope: Symptomatic hypotension with or without syncope may occur with carvedilol (usually within the first 30 days of therapy); close monitoring of patient is required especially with initial dosing and dosing increases; blood pressure must be lowered at a rate appropriate for the patient's clinical condition. Initiation with a low dose, gradual up-titration, and administration with food may help to decrease the occurrence of hypotension or syncope. Advise patients to avoid driving or other hazardous tasks during initiation of therapy due to the risk of syncope.
Disease-related concerns:
• Angina: Use with caution in patients suspected of having vasospastic angina.
• Bronchospastic disease: In general, patients with bronchospastic disease should not receive beta-blockers; if used at all, should be used cautiously with close monitoring.
• Diabetes: Use with caution in patients with diabetes mellitus; may potentiate hypoglycemia and/or mask signs and symptoms (eg, sweating, anxiety, tachycardia). In patients with heart failure and diabetes, use of carvedilol may worsen hyperglycemia; may require adjustment of antidiabetic agents.
• Heart failure with reduced ejection fraction: Stabilize patients on heart failure regimen prior to initiation or titration of beta-blocker. Beta-blocker therapy should be initiated at very low doses with gradual and careful titration. Worsening heart failure or fluid retention may occur during upward titration; dose reduction and/or slower titration may be necessary. Adjustment of other medications (ACE inhibitors and/or diuretics) may also be required.
• Myasthenia gravis: Use with caution in patients with myasthenia gravis.
• Peripheral vascular disease (PVD): May precipitate or aggravate symptoms of arterial insufficiency in patients with PVD; use with caution and monitor for progression of arterial obstruction.
• Pheochromocytoma (untreated): Use with caution; adequate alpha-blockade should be initiated prior to use of any beta-blocker.
• Psoriasis: Beta-blocker use has been associated with induction or exacerbation of psoriasis, but cause and effect have not been firmly established.
• Thyroid disease: May mask signs of hyperthyroidism (eg, tachycardia). If hyperthyroidism is suspected, carefully manage and monitor; abrupt withdrawal may exacerbate symptoms of hyperthyroidism or precipitate thyroid storm.
• Vasospastic angina: Beta-blockers without alpha1-adrenergic receptor blocking activity should be avoided in patients with vasospastic angina since unopposed alpha1-adrenergic receptors mediate coronary vasoconstriction and can worsen anginal symptoms (Mayer 1998).
Special populations:
• Older adult: Bradycardia may be observed more frequently in elderly patients (>65 years of age); dosage reductions may be necessary.
Dosage form specific issues:
• Polysorbate 80: Some dosage forms may contain polysorbate 80 (also known as Tweens). Hypersensitivity reactions, usually a delayed reaction, have been reported following exposure to pharmaceutical products containing polysorbate 80 in certain individuals (Isaksson 2002; Lucente 2000; Shelley 1995). Thrombocytopenia, ascites, pulmonary deterioration, and kidney and hepatic failure have been reported in premature neonates after receiving parenteral products containing polysorbate 80 (Alade 1986; CDC 1984). See manufacturer's labeling.
Other warnings/precautions:
• Abrupt withdrawal: Beta-blocker therapy should not be withdrawn abruptly (particularly in patients with CAD), but gradually tapered to avoid acute tachycardia, hypertension, and/or ischemia. Severe exacerbation of angina, ventricular arrhythmias, and myocardial infarction (MI) have been reported following abrupt withdrawal of beta-blocker therapy. Temporary and prompt resumption of beta-blocker therapy may be indicated with worsening of angina or acute coronary insufficiency.
• Major surgery: Chronic beta-blocker therapy should not be routinely withdrawn prior to major surgery.

Tablet, Oral:
Generic: 3.125 mg, 6.25 mg, 12.5 mg, 25 mg
Note: Multiple recipes for extemporaneously prepared suspensions exist; American Society of Health-System Pharmacists (ASHP) does not have a recommendation for a standard concentration; use caution and consult institutional protocols:
1.25 mg/mL oral suspension
A 1.25 mg/mL carvedilol oral suspension may be made with tablets and one of two different vehicles (Ora-Blend or 1:1 mixture of Ora-Sweet and Ora-Plus). Crush five 25 mg tablets in a mortar and reduce to a fine powder; add 15 mL of purified water and mix to a uniform paste. Mix while adding chosen vehicle in incremental proportions to almost 100 mL; transfer to a calibrated amber bottle, rinse mortar with vehicle, and add quantity of vehicle sufficient to make 100 mL. Label “shake well.” Stable for 84 days when stored in amber prescription bottles at room temperature (Loyd 2006).
0.1 and 1.67 mg/mL oral suspensions
Carvedilol oral liquid suspensions (0.1 mg/mL and 1.67 mg/mL) made from tablets, water, Ora-Plus, and Ora-Sweet were stable for 12 weeks when stored in glass amber bottles at room temperature (25°C). Use one 3.125 mg tablet for the 0.1 mg/mL suspension or two 25 mg tablets for the 1.67 mg/mL suspension; grind the tablet(s) and compound a mixture with 5 mL of water, 15 mL Ora-Plus, and 10 mL Ora-Sweet. Final volume of each suspension: 30 mL; label “shake well” (data on file, GlaxoSmithKline, Philadelphia, PA: DOF #132 [Note: Manufacturer no longer disseminates this document]).

Medications considered acceptable for the treatment of chronic hypertension during pregnancy may generally be used in patients trying to conceive. Carvedilol is not considered a preferred agent for use in pregnant patients; consider transitioning to a preferred agent in patients planning to become pregnant (ACC/AHA [Whelton 2018]; ACOG 2019; NICE 2019).
Impotence is noted in product labeling following use of carvedilol. As a class, outcomes from available studies evaluating beta-blockers and sexual dysfunction are inconsistent, and the negative effects on erectile function are considered controversial. A clear relationship between use of beta-blockers and erectile dysfunction has not been established. Hypertension itself is associated with erectile dysfunction. Patients on a beta-blocker presenting with sexual dysfunction should be evaluated for underlying disease (Farmakis 2022; Levine 2012; Semet 2017; Terentes-Printzios 2022; Viigimaa 2020).
Exposure to beta-blockers during pregnancy may increase the risk for adverse events in the neonate. If maternal use of a beta-blocker is needed, monitor fetal growth during pregnancy; monitor the newborn for 48 hours after delivery for bradycardia, hypoglycemia, and respiratory depression (ESC [Regitz-Zagrosek 2018]).
Chronic maternal hypertension is also associated with adverse events in the fetus/infant. Chronic maternal hypertension may increase the risk of birth defects, low birth weight, premature delivery, stillbirth, and neonatal death. Actual fetal/neonatal risks may be related to the duration and severity of maternal hypertension. Untreated chronic hypertension may also increase the risks of adverse maternal outcomes, including gestational diabetes, preeclampsia, delivery complications, stroke, and myocardial infarction (ACOG 2019).
Patients with preexisting hypertension may continue their medication during pregnancy unless contraindications exist (ESC [Regitz-Zagrosek 2018]). When treatment of hypertension is initiated during pregnancy, agents other than carvedilol may be preferred (ACOG 2019; ESC [Cífková 2020]; ESC [Regitz-Zagrosek 2018]; SOGC [Magee 2022]). Carvedilol may be considered for use in pregnant patients with heart failure (ESC [Regitz-Zagrosek 2018]).
Heart rate, blood pressure, weight, SCr, BUN, liver function; in patient with increased risk for developing renal dysfunction, monitor renal function during dosage titration.
As a racemic mixture, carvedilol has nonselective beta-adrenoreceptor and alpha-adrenergic blocking activity. No intrinsic sympathomimetic activity has been documented. Associated effects in hypertensive patients include reduction of cardiac output, exercise- or beta-agonist-induced tachycardia, reduction of reflex orthostatic tachycardia, vasodilation, decreased peripheral vascular resistance (especially in standing position), decreased renal vascular resistance, reduced plasma renin activity, and increased levels of atrial natriuretic peptide. In CHF, associated effects include decreased pulmonary capillary wedge pressure, decreased pulmonary artery pressure, decreased heart rate, decreased systemic vascular resistance, increased stroke volume index, and decreased right atrial pressure (RAP).
Onset of action: Antihypertensive effect: Alpha-blockade: Within 30 minutes; Beta-blockade: Within 1 hour
Peak antihypertensive effect: ~1 to 2 hours
Absorption: Oral: Rapid and extensive, but with large first pass effect; first pass effect is stereoselective with R(+) enantiomer achieving plasma concentrations 2 to 3 times higher than S(-) enantiomer; delayed with food
Distribution: Vd: 115 L; distributes into extravascular tissues
Protein binding: >98%, primarily to albumin
Metabolism: Extensively (98%) hepatic, via CYP2C9, 2D6, 3A4, 2C19, 1A2, and 2E1 (2% excreted unchanged); metabolized predominantly by aromatic ring oxidation and glucuronidation; oxidative metabolites undergo conjugation via glucuronidation and sulfation; three active metabolites (4-hydroxyphenyl metabolite is 13 times more potent than parent drug for beta-blockade, however, active metabolites achieve plasma concentrations of only 1/10 of those for carvedilol); first-pass effect; plasma concentrations in the elderly and those with cirrhotic liver disease are 50% and 4 to 7 times higher, respectively. Metabolism is subject to genetic polymorphism; CYP2D6 poor metabolizers have a 2- to 3-fold higher plasma concentration of the R(+) enantiomer and a 20% to 25% increase in the S(-) enantiomer compared to extensive metabolizers.
Bioavailability: Immediate release: ~25% to 35% (due to significant first-pass metabolism); Extended release: ~85% of immediate release; high-fat meal increases AUC and Cmax ~20%; bioavailability is increased in patients with CHF

R(+)-carvedilol: 5 to 9 hours
S(-)-carvedilol: 7 to 11 hours
Time to peak, plasma: Extended release: ~5 hours
Excretion: Primarily feces; urine (<2%, unchanged)
Altered kidney function: Plasma concentrations may be higher (40% to 50% in moderate to severe kidney impairment).
Hepatic function impairment: Severe hepatic impairment (cirrhosis) patients have a 4- to 7-fold increase in concentrations.
Older adult: Plasma levels are about 50% higher.
Heart failure: AUC and Cmax increased up to 100%.
