What is Coreg?

Coreg is a prescription medicine that belongs to a group of medicines called “beta-blockers”. Coreg is used, often with other medicines, for the following conditions:

  • to treat patients with certain types of heart failure
  • to treat patients who had a heart attack that worsened how well the heart pumps
  • to treat patients with high blood pressure (hypertension)

Coreg is not approved for use in children under 18 years of age.

What is high blood pressure (hypertension)?

Blood pressure is the force of blood in your blood vessels when your heart beats and when your heart rests. You have high blood pressure when the force is too much. High blood pressure makes the heart work harder to pump blood through the body and causes damage to blood vessels. Coreg can help your blood vessels relax so your blood pressure is lower. Medicines that lower blood pressure may lower your chance of having a stroke or heart attack.

Who should not take Coreg?

Do not take Coreg if you:

  • have severe heart failure and are hospitalized in the intensive care unit or require certain intravenous medications that help support circulation (inotropic medications).
  • are prone to asthma or other breathing problems.
  • have a slow heartbeat or a heart that skips a beat (irregular heartbeat).
  • have liver problems.
  • are allergic to any of the ingredients in Coreg. The active ingredient is carvedilol. See "What are the ingredients in Coreg?" for a list of all the ingredients in Coreg.

What should I tell my healthcare provider before taking Coreg?

Tell your doctor about all of your medical conditions, including if you:

  • have asthma or other lung problems (such as bronchitis or emphysema).
  • have problems with blood flow in your feet and legs (peripheral vascular disease). Coreg can make some of your symptoms worse.
  • have diabetes.
  • have thyroid problems.
  • have a condition called pheochromocytoma.
  • have had severe allergic reactions.
  • are pregnant or trying to become pregnant. It is not known if Coreg is safe for your unborn baby. You and your doctor should talk about the best way to control your high blood pressure during pregnancy.
  • are breastfeeding. It is not known if Coreg passes into your breast milk. Talk with your doctor about the best way to feed your baby if you are taking Coreg.
  • are scheduled for surgery and will be given anesthetic agents.
  • are scheduled for cataract surgery and have taken or are currently taking Coreg.
  • are taking prescription or over-the-counter medicines, vitamins, and herbal supplements. Coreg and certain other medicines can affect each other and cause serious side effects. Coreg may affect the way other medicines work. Also, other medicines may affect how well Coreg works.

Keep a list of all the medicines you take. Show this list to your doctor and pharmacist before you start a new medicine.

How should I take Coreg?

It is important for you to take your medicine every day as directed by your doctor. If you stop taking Coreg suddenly, you could have chest pain and/or a heart attack. If your doctor decides that you should stop taking Coreg, your doctor may slowly lower your dose over a period of time before stopping it completely.

  • Take Coreg exactly as prescribed. Your doctor will tell you how many tablets to take and how often. In order to minimize possible side effects, your doctor might begin with a low dose and then slowly increase the dose.
  • Do not stop taking Coreg and do not change the amount of Coreg you take without talking to your doctor.
  • Tell your doctor if you gain weight or have trouble breathing while taking Coreg.
  • Take Coreg with food.
  • If you miss a dose of Coreg, take your dose as soon as you remember, unless it is time to take your next dose. Take your next dose at the usual time. Do not take 2 doses at the same time.
  • If you take too much Coreg, call your doctor or poison control center right away.
