Lopressor

Generic name: Metoprolol tartrate

Why is Lopressor prescribed?

Lopressor, a type of medication known as a beta blocker, is used in the treatment of high blood pressure, angina pectoris (chest pain, usually caused by lack of oxygen to the heart due to clogged arteries), and heart attack. When prescribed for high blood pressure, it is effective when used alone or in combination with other high blood pressure medications. Beta blockers decrease the force and rate of heart contractions, thereby reducing the demand for oxygen and lowering blood pressure.

Occasionally doctors prescribe Lopressor for the treatment of aggressive behavior, prevention of migraine headache, and relief of temporary anxiety.

An extended-release form of this drug, called Toprol-XL, is prescribed for high blood pressure, angina, and heart failure.

Most important fact about Lopressor

If you have high blood pressure, you must take Lopressor regularly for it to be effective. Since blood pressure declines gradually, it may be several weeks before you get the full benefit of Lopressor; and you must continue taking it even if you are feeling well. Lopressor does not cure high blood pressure; it merely keeps it under control.

How should you take Lopressor?

Lopressor should be taken with food or immediately after you have eaten.

Take Lopressor exactly as prescribed, even if your symptoms have disappeared.

Try not to miss any doses. If this medication is not taken regularly, your condition may worsen.

• If you miss a dose...

What side effects may occur?
