Oral route(Tablet, Extended Release)

Exacerbations of angina pectoris and, in some cases, myocardial infarction have occurred after abrupt cessation of therapy with certain beta-blocking agents. When discontinuing chronic therapy, gradually reduce the dose over a period of 1 to 2 weeks and monitor the patient carefully. If angina markedly worsens or acute coronary insufficiency develops, reinstate administration promptly, at least temporarily, and take other measures appropriate for the management of unstable angina. Warn patients not to interrupt or discontinue therapy without physician advice .

Oral route(Tablet)

Following abrupt cessation of therapy with certain beta-blocking agents, exacerbations of angina pectoris and, in some cases, myocardial infarction have occurred. The dosage should be gradually reduced over a period of 1 to 2 weeks and the patient should be carefully monitored when discontinuing chronic therapy. If angina markedly worsens or acute coronary insufficiency develops, metoprolol tartrate administration should be reinstated promptly, at least temporarily, and other measures appropriate for the management of unstable angina should be taken. Patients should be warned against interruption or discontinuation of therapy without the physician’s advice. Because coronary artery disease is common and may be unrecognized, it may be prudent not to discontinue metoprolol tartrate therapy abruptly even in patients treated only for hypertension .

Uses for Lopressor

Metoprolol is used alone or together with other medicines to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. A lower blood pressure can reduce the risk of strokes and heart attacks.

Metoprolol is also used to treat severe chest pain (angina) and lowers the risk of repeated heart attacks. It is given to people who have already had a heart attack. In addition, metoprolol is used to treat patients with heart failure.

This medicine is a beta-blocker. It works by affecting the response to nerve impulses in certain parts of the body, like the heart. As a result, the heart beats slower and decreases the blood pressure. When the blood pressure is lowered, the amount of blood and oxygen is increased to the heart.

This medicine is available only with your doctor’s prescription.

Before using Lopressor

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of metoprolol tablets in the pediatric population. Safety and efficacy have not been established.

Appropriate studies have not been performed on the relationship of age to the effects of metoprolol extended-release tablets and extended-release capsules in children younger than 6 years of age. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of metoprolol in the elderly. However, elderly patients are more likely to have age-related liver, kidney, or heart problems, which may require caution and an adjustment in the dose for patients receiving metoprolol.

Breastfeeding

Studies in women suggest that this medication poses minimal risk to the infant when used during breastfeeding.

Proper use of Lopressor

This section provides information on the proper use of a number of products that contain metoprolol. It may not be specific to Lopressor. Please read with care.

Take this medicine only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. Your dose may need to be changed several times in order to find out what works best for you.

In addition to the use of this medicine, treatment for your high blood pressure may include weight control and changes in the types of food you eat, especially foods high in sodium (salt). Your doctor will tell you which of these are most important for you. You should first check with your doctor before changing your diet.

Many patients who have high blood pressure will not notice any signs of the problem. In fact, many patients feel normal. It is very important that you take your medicine exactly as directed and that you keep your appointments with your doctor even if you feel well.

Remember that this medicine will not cure your high blood pressure, but it does help control it. You must continue to take it as directed if you expect to lower your blood pressure and keep it down. You may have to take high blood pressure medicine for the rest of your life. If high blood pressure is not treated, it can cause serious problems such as heart failure, blood vessel disease, strokes, or kidney disease.

  • You may also use a nasogastric tube to give the medicine. Mix the contents of the opened capsule with water into a syringe. Gently shake the mixture for about 10 seconds, then flush it through the tube. Rinse the tube with water until all of the medicine is washed out.

Take the tablet or extended-release tablet with a meal or just after you eat. You may break the extended-release tablet into two pieces, but swallow the two pieces whole and do not crush or chew them.

Precautions while using Lopressor

It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly. Blood tests may be needed to check for unwanted effects.

Metoprolol may worsen the symptoms of heart failure in some patients. Check with your doctor right away if you are having chest pain or discomfort, dilated neck veins, extreme fatigue, irregular breathing or heartbeat, shortness of breath, swelling of the face, fingers, feet, or lower legs, or weight gain.

Do not suddenly stop taking this medicine without first checking with your doctor. Your doctor may want you to gradually reduce the amount you are taking before stopping it completely. Some conditions may become worse when the medicine is stopped suddenly, which can be dangerous.

This medicine may cause changes in blood sugar levels. Also, this medicine may cover up the symptoms of low blood sugar, such as a rapid pulse rate. Check with your doctor if you notice a change in your normal symptoms or a change in the results of your blood or urine sugar tests.

Make sure any doctor or dentist who treats you knows that you are using this medicine. You may need to stop using this medicine several days before having surgery.

This medicine may cause some people to become less alert than they are normally. Do not drive or do anything else that could be dangerous until you know how this medicine affects you.

Dizziness, lightheadedness, or even fainting may occur when you get up suddenly from a lying or sitting position. Getting up slowly may help lessen this problem. Also, lying down for a while may relieve the dizziness or lightheadedness.

Avoid drinking alcohol while you are using the extended-release capsules.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems, since they may increase your blood pressure.
