Metoprolol Succinate Oral

Warnings  
If you have chest pain (angina) or heart disease (e.g., coronary artery disease, ischemic heart disease, high blood pressure), do not stop using this drug without first consulting your doctor. Your condition may become worse when the drug is suddenly stopped. 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. Seek immediate medical attention if you develop: worsening chest pain, tightness or pressure in the chest, chest pain spreading to the jaw/neck/arm, sweating, trouble breathing or fast/irregular heartbeat.

 

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 section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.

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