WARNING: Do not stop using this drug without first consulting your doctor. Your condition may become worse when the drug is suddenly stopped, especially if you have chest pain (angina) or have heart disease (e.g., coronary artery disease, ischemic heart disease, heart failure, high blood pressure). If your doctor decides you should no longer use this drug, you must gradually decrease your dose according to your doctor's instructions. When gradually stopping this medication, it is recommended that you temporarily limit physical activity to decrease the work on the heart.

This medication is an alpha- and beta-blocker used to treat high blood pressure and heart failure. It is also used after an acute heart attack to improve survival. High blood pressure reduction helps prevent strokes, heart attacks and kidney problems. This drug works by blocking the action of certain natural chemicals in your body such as epinephrine on the heart and blood vessels. This results in a lowering of the heart rate, blood pressure, and strain on the heart.
