Uses

What is Coreg® (carvedilol) used for?

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

Coreg® may also be used for purposes not listed in this medication guide.

How should I take Coreg® (carvedilol)?

Take Coreg® exactly as prescribed by your doctor. Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not take this medicine in larger or smaller amounts or for longer than recommended.

Coreg® works best if you take it with food.

You may open the Coreg® CR capsule and sprinkle the medicine into a spoonful of pudding or applesauce to make swallowing easier. Swallow right away without chewing. Do not save the mixture for later use. Discard the empty capsule.

Take at the same time every day. Do not skip doses or stop taking this medicine without first talking to your doctor. Stopping suddenly may make your condition worse.

If you are switched from Coreg® tablets to Coreg® CR extended-release capsules, your daily total dose of this medicine may be higher or lower than before. Older adults may be more likely to become dizzy or feel faint when switching from tablets to extended-release capsules. Follow your doctor’s instructions.

Your blood pressure will need to be checked often.

If you are being treated for high blood pressure, keep using this medication 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 life.

If you need surgery, tell the surgeon ahead of time that you are using Coreg®. You may need to stop using the medicine for a short time.

You should not stop using Coreg® suddenly. Stopping suddenly may make your condition worse.
