Warnings and Precautions
If you are prescribed COREG, you should never stop taking it without first speaking to your doctor.
If your physician decides to take you off COREG, he/she may gradually decrease your dose over one to two weeks.
If your dose is decreased, it's a good idea to limit your physical activity to reduce strain on your heart.
Seek medical attention right away if you develop chest pain, tightness, pressure, or chest pain that spreads to your jaw, neck, or arm.
Other signs of serious problems are unusual sweating, trouble breathing, or a fast or irregular heartbeat.
If you have severe liver disease or certain heart conditions you should not use this medication either.
People with a slow heart rate who don't have pacemakers should inform their doctor before starting this medication.
Be sure to tell your doctor whether you have asthma or other breathing problems, liver disease, or a slow/irregular heartbeat.
You also need to mention any current or past blood flow problems in your feet or legs; diabetes and other conditions that might result in low blood sugar; low blood pressure; or hyperthyroidism, which results in too much thyroid hormone in your body.
Also on the must-disclose list: Chest pain that occurs for no obvious reason when you are resting (Prinzmetal's angina) and the condition pheochromocytoma, where a tumor appears on a gland near the kidneys, perhaps leading to a fast heartbeat or high blood pressure.
Before having surgery, including dental surgery, let your doctor know that you're using COREG.
