Coreg and Heart Failure: Drug Facts, Dosing, and Side Effects

Coreg Drug Facts

Carvedilol or Coreg is used to treat congestive heart failure (a condition in which the heart cannot pump enough blood to all parts of the body) and high blood pressure

. It also is used to treat people who have had a heart attack. Carvedilol is often used in combination with other medications.

Carvedilol is in a class of medications called beta-blockers. It works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure.

Role of Beta-Blockers in Heart Failure

High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys and other parts of the body.

Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. Studies have shown that coreg has the ability to increase the ejection fraction of the heart.

Coreg has also been effective in remodeling the heart. Also, people were admitted to the hospital less frequently when they took Coreg. Mortality and morbidity were also lower in people who took coreg.

Large-scale randomized, placebo-controlled trials involving more than 4000 patients with chronic heart failure have demonstrated that carvedilol improves survival and reduces hospitalizations.

Lifestyle Changes

In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in carbohydrates, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.

There are some natural alternatives to beta blockers as well. Check out these alternatives below:





Coreg has a place in heart failure. However, it can be a difficult drug to tolerate because of its side effects. For some reason, CVoreg is considered the ” gold standard” treatment for heart failure. However, it does not matter if it is the gold standard if you can’t tolerate it.

Coreg decreases adrenaline in your body. Therefore, it is common for people to feel weak with no energy. Congestive heart failure is a very challenging disease. You should not have to feel bad from medicine as well.

My advice to you is to talk to your health care provider immediately. If the provider is unwilling to listen to you, it might be time for a new provider.
