Lopressor (Metoprolol)

Drug Uses

Lopressor is used for treating high blood pressure, alone or with other medicines; long-term treatment of chest pain; and reducing the risk of death because of heart problems in patients who have had a heart attack. It may also be used for other conditions as determined by your doctor.

How to use

Use Lopressor as directed by your doctor.

• Take Lopressor exactly as it was prescribed for you. Do not take the medication in larger amounts or for longer than recommended by your doctor.
• Take this medication with a full glass of water.
• To be sure this medication is helping your condition, your blood pressure will need to be checked on a regular basis. It is important that you not miss any scheduled visits to your doctor.

Drug Class and Mechanism

Lopressor is a beta-adrenergic blocking agent. It works by reducing the amount of work the heart has to do (reduces chest pain) and the amount of blood the heart pumps out (lowers high blood pressure). It is also used to stabilize the heart rhythm in conditions in which the heart is beating too fast or at an irregular rhythm.

Missed Dose

If you miss a dose of Lopressor , use it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not use 2 doses at once.
