Carvedilol is a versatile medication primarily used for treating cardiovascular conditions such as heart failure, high blood pressure, and left ventricular dysfunction.
As both an alpha and beta-blocker, it offers unique benefits by simultaneously relaxing blood vessels and reducing heart rate, improving blood flow throughout the body.
Carvedilol has demonstrated significant effectiveness in improving survival rates after heart attacks and enhancing quality of life for patients with chronic heart conditions.
What is Carvedilol Tablet?
Carvedilol, marketed among others under the brand name Coreg, is a drug used in people who are otherwise healthy to treat
Elevated blood pressure,
Congestive heart failure
Left ventricular dysfunction.
It is usually a second-line therapy for high blood pressure. It is swallowed by the mouth.
What are the Uses of Carvedilol?
Carvedilol offers multiple therapeutic benefits through its unique dual-action mechanism. It is primarily used to manage cardiovascular conditions and improve patient outcomes.
Conditions Carvedilol Treats
Carvedilol is approved for treating several cardiovascular conditions:
Heart failure (condition where the heart cannot pump enough blood to all parts of the body)
High blood pressure (hypertension)
Left ventricular dysfunction following a heart attack
It's often used as a second-line therapy for high blood pressure
Secondary Uses of Carvedilol
Beyond its primary indications, carvedilol is utilized off-label for:
Stable angina pectoris
Atrial fibrillation
Prophylaxis against cirrhotic esophageal variceal bleeding
Management of ventricular arrhythmias
How Does Carvedilol Work?
Carvedilol operates through a multi-faceted mechanism of action that differentiates it from standard beta-blockers.
Carvedilol works by blocking both beta and alpha-1 adrenergic receptors in the body. It reversibly binds to β-adrenergic receptors on cardiac myocytes, preventing the sympathetic nervous system's response and leading to decreased heart rate and contractility.
This action is particularly beneficial in heart failure patients where the sympathetic nervous system is activated as a compensatory mechanism.
Additionally, carvedilol's blockade of α1 1-adrenergic receptors causes vasodilation of blood vessels. This inhibition leads to decreased peripheral vascular resistance and blood pressure.
The combined effect creates a more balanced cardiovascular response than either pure beta-blockers or vasodilators alone, reducing strain on the heart while improving blood flow.
Carvedilol Available Forms:
Carvedilol is available in the following oral dosage forms:
Immediate-release tablets: Common strengths include 3.125 mg, 6.25 mg, 12.5 mg, and 25 mg.

Both forms are taken by mouth. The immediate-release tablets are typically taken twice daily, while the extended-release capsules are usually taken once daily. There are no injectable or liquid oral forms of carvedilol widely available.
Carvedilol Dosage
The appropriate dosage of carvedilol tablets varies based on the condition being treated and individual patient factors.
Typical Dosage Instructions
For hypertension:
Starting dose: Usually 6.25 mg twice daily
Maintenance dose: 12.5-50 mg daily, divided into two doses
For heart failure:
Starting dose: 3.125 mg twice daily for two weeks
Dose may be doubled every two weeks to the highest tolerated level
Maximum dose: 25-50 mg twice daily, depending on patient weight
What Should I Do If I Miss a Dose?
If you miss a dose of carvedilol, take it as soon as you remember. However, if it's almost time for your next dose, skip the missed dose and take your next dose at the regular time. Never take two doses to make up for a missed one.
What Happens If an Overdose?
Overdosing on carvedilol can cause serious side effects, including:
Extremely low blood pressure
Severely slow heart rate
Fainting
Difficulty breathing
Seizures
If overdose is suspected, seek immediate medical attention or contact a Poison Control Center right away.
Get a second opinion from trusted experts and makeconfident, informed decisions.
If you experience any serious side effects, contact your doctor immediately. For severe symptoms like chest pain or difficulty breathing, seek emergency medical help.
Precautions and Warnings
Several important precautions should be considered before and during carvedilol therapy.
Who Should Avoid This Medicine
Carvedilol is contraindicated in patients with:
Known hypersensitivity to carvedilol
Severe bronchial asthma or related bronchospastic conditions
Second or third-degree AV block (unless a permanent pacemaker is in place)
Are There Any Age Restrictions for Using Carvedilol?
Carvedilol has not been established as safe and effective for use in people under 18 years of age. Seniors may be more sensitive to the effects of carvedilol, particularly dizziness and lightheadedness.
Alcohol or Food Interactions
Alcohol should be avoided while taking carvedilol as it can increase the risk of dizziness, lightheadedness, and fainting. Alcohol may also worsen the blood pressure-lowering effects of carvedilol, potentially causing dangerously low blood pressure.
Possible Interactions with Other Medications (Drug Interactions)
Carvedilol can interact with numerous medications, potentially affecting its efficacy or safety.
Carvedilol may interact with:
Other blood pressure medications (increased risk of low blood pressure)
Fingolimod (increased risk of bradycardia)
Insulin or oral diabetes medications (may mask symptoms of hypoglycemia)
Calcium channel blockers (increased risk of conduction disturbances)
NSAIDs like ibuprofen (may reduce blood pressure-lowering effects)
Certain antidepressants like fluoxetine (increased carvedilol levels)
Cough and cold medications containing pseudoephedrine or phenylephrine
Always inform your healthcare provider about all medications, supplements, and herbal products you are taking before starting carvedilol.
How Should Carvedilol Be Stored?
Proper storage helps preserve the effectiveness and safety of carvedilol throughout its shelf life. Keep it in recommended conditions to prevent loss of potency or degradation.
Recommended Storage Temperature for Carvedilol
Store carvedilol tablets at room temperature between 68° F and 77° F (20° C to 25° C). Extended-release capsules (Coreg CR) should be stored at 77° F (25° C), though temporary exposure to temperatures between 59° F to 86° F (15° C to 30° C) is acceptable during transport.
What Happens If Carvedilol Is Not Stored Properly?
Improper storage may lead to degradation of the medication, potentially reducing its effectiveness or safety. Keep carvedilol in its original container, tightly closed, and protect it from light and moisture. Avoid storing in bathrooms where humidity levels can be high.

Carvedilol is used for treating high blood pressure and heart failure. It helps reduce the workload on the heart and control heart rhythm.
Misoprostol is used to prevent and treat stomach ulcers, induce labor, cause abortion, and manage postpartum bleeding due to poor uterine contraction.
Carvedilol may cause blood pressure to drop dangerously low, which can lead to loss of consciousness. This risk is highest after the first dose and may increase with dosage adjustments. Taking carvedilol with food helps reduce this risk.
The extended-release capsule is typically taken with food once a day in the morning. Try to take carvedilol at the same time each day. Follow the instructions on your prescription label carefully, and consult your doctor or pharmacist if you have any questions or concerns.
No, carvedilol is not an antidepressant.
No, carvedilol is not a diuretic. It is a beta-blocker used to manage high blood pressure and heart failure. While it may be prescribed alongside diuretics, it does not act as a water pill itself.
The usual dosing schedule for carvedilol is every 12 hours, as directed by a healthcare provider. This schedule helps maintain consistent levels of the medication in the body for optimal effectiveness.
An overdose of carvedilol can lead to serious health issues such as extremely low blood pressure, slow heart rate, dizziness, fainting, trouble breathing, and possibly cardiac arrest. Seek immediate medical attention if an overdose is suspected.
Carvedilol has been linked to rare cases of liver injury, including elevated liver enzymes. Severe liver damage is uncommon and often reversible after stopping the medication. Liver function monitoring may be advised, especially for those with existing liver conditions.
Carvedilol 3.125 mg and 6.25 mg are used to treat high blood pressure (hypertension), heart failure, and to improve survival after a heart attack. The 3.125 mg dose is often used as a starting dose in heart failure to allow the body to adjust to the medication, while 6.25 mg may be used as a maintenance dose or as the next step in dose escalation. Carvedilol works by blocking beta and alpha receptors, which helps lower blood pressure, reduce heart rate, and decrease the workload on the heart.
