USES: This medication is a beta-blocker used to treat chest pain (angina), heart failure, and 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.

OTHER USES: This medication may also be used for irregular heartbeats, migraine headache prevention, and after an acute heart attack to improve survival.

HOW TO USE: Take this medication by mouth usually once daily in the morning, with or without food, or as directed by your doctor. Use this medication regularly in order to get the most benefit from it. Remember to use it at the same time each day. Swallow this medication whole. Do not crush, chew, or break the tablet before swallowing. This drug is not effective if you use it only when chest pain or a migraine headache occurs. It is very important to take this medication regularly as prescribed to help prevent these conditions. The dosage is based on your medical condition and response to therapy. It may take one or two weeks before the full benefit of this drug takes effect. It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick. Do not suddenly stop taking this medication without consulting your doctor. Your condition may become worse when the drug is suddenly stopped. Refer to the Warning section.
