Coreg CR (carvedilol phosphate) is a once-a-day heart medication that belongs to a class of drugs known as beta-blockers.

Coreg CR is used to treat hypertension (high blood pressure), heart failure, and left ventricular dysfunction associated with a heart attack.

Use and Dosage

Read the Patient Information Leaflet if available from your pharmacist before you start taking carvedilol and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with food as directed by your doctor, usually once daily in the morning.

Swallow the capsule whole. Do not crush or chew the capsule.

If you cannot swallow the capsule, you may open the capsule and sprinkle the beads over cool, smooth applesauce. Do not chew the mixture because doing so may cause the drug to be released too quickly, increasing side effects. Swallow all of the mixture right away. Do not prepare the mixture ahead of time for later use.

The dosage is based on your medical condition and response to treatment. To reduce your risk of side effects, your doctor may direct you to start this medication at a low dose and gradually increase your dose. Follow your doctor’s instructions carefully.

Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day.

For the treatment of high blood pressure, it may take 1 to 2 weeks before you get the full benefit of this drug. Keep taking this medication even if you feel well. Most people with high blood pressure do not feel sick.

Tell your doctor if your condition does not improve or if it worsens (for example, your blood pressure readings remain high or increase, or you have worsening symptoms of heart failure like increased shortness of breath).

Side Effects

Get emergency medical help if you have any of these signs of an allergic reaction to carvedilol: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once if you have a serious side effect such as:

  • A light-headed feeling, like you might pass out
  • Slow or uneven heartbeats
  • Swelling, rapid weight gain, or feeling short of breath (even with mild exertion)
  • Cold feeling or numbness in your fingers or toes
  • Chest pain, dry cough, wheezing, chest tightness, or trouble breathing
  • High blood sugar (increased thirst, increased urination, hunger, dry mouth, fruity breath odor, drowsiness, dry skin, blurred vision, or weight loss)

Common carvedilol side effects may include:

  • Weakness or dizziness
  • Diarrhea
  • Dry eyes
  • Tired feeling
  • Weight gain

This is not a complete list of side effects and others may occur.


Before taking carvedilol, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

Before using this medication, tell your doctor or pharmacist your medical history, especially of: certain types of heartbeat/heart rhythm problems (such as slow/irregular heartbeat, sick sinus syndrome, second- or third-degree atrioventricular block), breathing problems (such as asthma, chronic bronchitis, emphysema), severe heart failure requiring hospitalization, liver disease, kidney disease, blood circulation problems (such as Raynaud’s disease, peripheral vascular disease), serious allergic reactions including those needing treatment with epinephrine, overactive thyroid disease (hyperthyroidism), a certain type of tumor (pheochromocytoma), other heart problems (such as Prinzmetal’s variant angina), a certain muscle disease (myasthenia gravis), certain eye problems (cataracts, glaucoma).

This drug may make you dizzy, drowsy, or cause you to faint. This is most likely to occur within 1 hour after taking your dose, especially when you start carvedilol treatment or any time your doctor increases your dose. During these periods, avoid driving and doing hazardous tasks. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).

People who wear contact lenses may have dry eyes while taking this medication.

Before having surgery (including cataract/glaucoma eye surgery), tell your doctor or dentist if you are taking or have ever taken this medication, and about all the other products you use (including prescription drugs, nonprescription drugs, and herbal products).

This product may prevent the fast/pounding heartbeat you would usually feel when your blood sugar level falls too low (hypoglycemia). The risk is higher if you have diabetes, or are vomiting, fasting, or not eating regularly. Other symptoms of low blood sugar levels, such as dizziness and sweating, are not affected by this drug.

If you have diabetes, this product may make it harder to control your blood sugar levels. Check your blood sugar levels regularly as directed by your doctor. Tell your doctor right away if you have symptoms of high blood sugar such as increased thirst/urination. Your doctor may need to adjust your diabetes medication, exercise program, or diet.

Children may be at greater risk for low blood sugar (hypoglycemia) while using this drug, especially if they are vomiting or not eating regularly. To help prevent low blood sugar, make sure children eat regularly. If your child cannot eat regularly, is vomiting, or has symptoms of low blood sugar (such as sweating, and shaking), tell the doctor right away.

Older adults may be more sensitive to the side effects of this drug, especially dizziness and lightheadedness.

Tell your doctor if you are pregnant or plan to become pregnant. You should not become pregnant while using carvedilol. Carvedilol may harm an unborn baby. If you become pregnant, talk to your doctor right away about the risks and benefits of this medication.

It is unknown if carvedilol passes into breast milk. However, it is unlikely to pass into breast milk in large amounts. There is a low risk that it may have undesirable effects on a nursing infant. Consult your doctor before breastfeeding.

What to avoid?

Carvedilol may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.

Drinking alcohol can further lower your blood pressure and may increase certain side effects of carvedilol. You should especially avoid drinking alcohol within 2 hours before or after taking extended-release carvedilol (Coreg CR).

Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.
