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 heart disease (such as coronary artery disease, ischemic heart disease, 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 strain on the heart.

This medication is a beta blocker used to treat high blood pressure. Lowering high blood pressure 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) that affect the heart and blood vessels. This results in a lowering of heart rate, blood pressure, and strain on the heart.

Consult your doctor or pharmacist for details.
