Generic name: carvedilol [ KAR-ve-dil-ole ]
Brand names: Coreg, Coreg CR
Drug class: Non-cardioselective beta blockers
What is Coreg?
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.
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
