What is Coreg?Coreg is used, often with other medications, to treat high blood pressure. It is also used to treat patients who had a heart attack that reduced how well the heart pumps (left ventricular dysfunction, or LVD), and to treat patients with certain types of heart failure.
What is the most important information I should know about Coreg?If you are taking Coreg, do not suddenly stop taking it, as this may lead to chest pain and, in some cases, heart attack. If your doctor decides that you should stop taking Coreg, he or she will slowly reduce your dose over a period of time before stopping it completely.
Coreg can cause a drop in blood pressure when you first stand up, resulting in dizziness or even fainting. If this happens, sit or lie down and notify your doctor. Taking the drug with food reduces the chance of this problem. During the first month of therapy and after a change in your dose, use caution when driving or operating dangerous machinery.
Coreg may hide the symptoms of low blood sugar. Monitor blood sugar levels and report any changes to your doctor.
Rarely, Coreg leads to worsened kidney function in heart failure patients, so your kidney function should be monitored if your doctor increases your dose of Coreg.
If you experience symptoms of heart failure, such as weight gain and shortness of breath, contact your doctor immediately.
Who should not take Coreg?Do not use Coreg if you have breathing problems, certain serious heart conditions (such as a slow or irregular heartbeat), or liver disease.
Do not take Coreg if you are allergic to it or any of its ingredients.
What should I tell my doctor before I take the first dose of Coreg?Tell your doctor about all prescription, over-the-counter, and herbal medications you are taking before beginning treatment with Coreg. Also, talk to your doctor about your complete medical history, especially if you have lung problems, high blood sugar, thyroid problems, liver disease, problems with blood flow to the feet/legs, pheochromocytoma (a rare tumor that develops in the adrenal gland), or are scheduled for surgery involving anesthetics. Also, tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding.
