Metoprolol Tartrate (generic Lopressor)
Member Price: $10
Metoprolol is used with or without other medications to treat high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. This medication is also used to treat chest pain (angina) and to improve survival after a heart attack.
Metoprolol belongs to a class of drugs known as beta blockers. It works by blocking the action of certain natural chemicals in your body, such as epinephrine, on the heart and blood vessels. This effect lowers the heart rate, blood pressure, and strain on the heart.
How to use Lopressor
Take this medication by mouth, with or right after a meal, as directed by your doctor, usually 1-3 times a day. The dosage is based on your medical condition and response to treatment.
To reduce your risk of side effects, your doctor may direct you to start this medication at a low dose and gradually increase your dose. Follow your doctor’s instructions carefully.
Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time(s) each day. Do not suddenly stop taking this medication without consulting your doctor. Your condition may become worse when the drug is suddenly stopped.
For the treatment of high blood pressure, it may take several weeks before you get the full benefit of this drug. Keep taking this medication even if you feel well. Most people with high blood pressure do not feel sick.
To prevent chest pain, a second heart attack, or migraine headaches, it is very important to take this medication regularly as prescribed. This drug should not be used to treat chest pain or migraines when they occur. Use other medications to relieve sudden attacks as directed by your doctor (for example, nitroglycerin placed under the tongue for chest pain, “triptan” drugs such as sumatriptan for migraines). Consult your doctor or pharmacist for details.
Tell your doctor if your condition does not improve or if it worsens (for example, if your routine blood pressure readings remain high or increase, if your chest pain or migraines occur more often).
