Coreg is a beta-blocker. Beta-blockers affect the heart and circulation (blood flow through arteries and veins).

Coreg is used to treat heart failure and hypertension (high blood pressure).

Coreg is also used after a heart attack that has caused your heart not to pump as well.

Warnings

You should not take Coreg if you have asthma, bronchitis, emphysema, severe liver disease, or a serious heart condition such as heart block, “sick sinus syndrome,” or slow heart rate (unless you have a pacemaker).

Avoid drinking alcohol within 2 hours before or after taking extended-release Coreg CR capsules. Also avoid taking medicines or other products that might contain alcohol. Alcohol may cause the carvedilol in the controlled release (CR) capsule to be released too quickly into the body.

If you are being treated for high blood pressure, keep using Coreg even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your l

Before taking this medicine

You should not take Coreg if you are allergic to carvedilol, or if you have:

• a serious heart condition such as severe heart failure, heart block, “sick sinus syndrome,” or slow heart rate (unless you have a pacemaker).

To make sure Coreg is safe for you, tell your doctor if you have:

• coronary artery disease (clogged arteries);
• slow heartbeats that have caused you to faint;
• fluid retention;
• asthma or other lung problems;
• angina (chest pain);
• diabetes (taking carvedilol can make it harder for you to tell when you have low blood sugar);
• a thyroid disorder;

Propranolol is used to treat tremors, angina (chest pain), hypertension (high blood pressure), heart rhythm disorders, and other heart or circulatory conditions. It is also used to treat or prevent heart attack, and to reduce the severity and frequency of migraine headaches.

Hemangeol (propranolol oral liquid 4.28 milligrams) is given to infants 5 weeks to 1 year old to treat a genetic condition called infantile hemangiomas. Hemangiomas are caused by blood vessels grouping together in an abnormal way. These blood vessels form benign (non-cancerous) growths that can develop into ulcers or red marks on the skin. Hemangiomas can also cause more serious complications inside the body (in the liver, brain, or digestive system).

Warnings

You should not use propranolol if you have asthma, very slow heart beats, or a serious heart condition such as “sick sinus syndrome” or “AV block” (unless you have a pacemaker).

Babies who weigh less than 4.5 pounds should not be given Hemangeol oral liquid.

How should I take propranolol?

Take propranolol exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.

Adults may take propranolol with or without food, but take it the same way each time.

Hemangeol must be given to an infant during or just after a feeding. Doses should be spaced at least 9 hours apart. Measure Hemangeol with the supplied measuring device (not a kitchen spoon). Do not shake.

Hemangeol can cause low blood sugar (hypoglycemia), especially during times of stress, illness, infections, or skipped meals. Make sure your child eats regularly while taking this medicine.

Call your doctor if a child taking Hemangeol is sick with vomiting, has missed a meal, or has signs of hypoglycemia such as severe weakness or seizure.

Doses are based on weight in children. Your child’s dose may change if the child gains or loses weight.

Your heart function and blood pressure will need to be checked often.

Tell your doctor if you have a planned surgery.

Your condition may get worse if you stop using propranolol suddenly. Ask your doctor before stopping the medicine.

This medicine can affect the results of certain medical tests. Tell any doctor who treats you that you are using propranolol.

If you have high blood pressure, keep using this medicine even if you feel well. High blood pressure often has no symptoms.

Store at room temperature away from moisture and heat. Do not freeze Hemangeol. Throw away any unused Hemangeol 2 months after you first opened the bottle.

What happens if I miss a dose?

Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line .
