- BRAND NAME (Manufacturer)
-
- Lopressor (Geigy)
-
- TYPE OF DRUG
-
- Beta-adrenergic blocking agent
-
- INGREDIENT
-
- metoprolol
-
- DOSAGE FORM
-
- Tablets (50 mg and 100 mg)
-
- STORAGE
-
- Metoprolol should be stored at room temperature in a tightly closed,
- light-resistant container.
-
- USES
-
- Metoprolol is used to treat high blood pressure and angina (chest pain)
- and to prevent additional heart attacks in heart attack patients. Metoprolol
- belongs to a group of medicines known as beta-adrenergic blocking agents or,
- more commonly, beta blockers. These drugs work by controlling nerve impulses
- along certain nerve pathways.
-
- TREATMENT
-
- Metoprolol can be taken with a glass of water, with meals, immediately
- following meals, or on an empty stomach, depending on your doctor's
- instructions. Try to take the medication at the same time(s) each day.
- Try not to miss any doses of this medicine. If you do miss a dose of the
- medication, take the missed dose as soon as possible. However, if the next
- scheduled dose is within eight hours (if you are taking this medicine only
- once a day) or within four hours (if you are taking this medicine more than
- once a day), do not take the missed dose of the medication at all; just return
- to your regular dosing schedule. Do not double the next dose of the
- medication.
- It is important to remember that metoprolol does not cure high blood
- pressure, but it will help to control the condition as long as you continue to
- take it.
-
- SIDE EFFECTS
-
- Minor.
-
- Anxiety; cold hands or feet (due to decreased blood circulation to the
- skin, fingers, and toes); constipation; decreased sexual ability; diarrhea;
- difficulty in sleeping; drowsiness; dryness of the eyes, mouth, and skin;
- headache; nausea; nervousness; stomach discomfort; tiredness; or weakness.
- These side effects should disappear during treatment, as your body adjusts to
- the medicine.
- If you are extra-sensitive to the cold, be sure to dress warmly during
- cold weather.
- To relieve constipation, increase the amount of fiber in your diet (fresh
- fruits and vegetables, salads, bran, and whole-grain breads) and exercise more
- (unless your doctor directs you to do otherwise).
- Plain, nonmedicated eye drops (artificial tears) may help to relieve eye
- dryness.
- Chew sugarless gum or suck on ice chips or a piece of hard candy to
- relieve mouth or throat dryness.
-
- Major.
-
- Tell your doctor about any side effects that are persistent or
- particularly bothersome. IT IS ESPECIALLY IMPORTANT TO TELL YOUR DOCTOR about
- breathing difficulty or wheezing, confusion, dizziness, fever and sore throat,
- hair loss, hallucinations, light-headedness, mental depression, nightmares,
- numbness or tingling of the fingers or toes, rapid weight gain (three to five
- pounds within a week), reduced alertness, skin rash, swelling, or unusual
- bleeding or bruising.
-
- INTERACTIONS
-
- Metoprolol interacts with several other types of medications:
- 1. Indomethacin, aspirin, or other salicylates may decrease the
- blood-pressure-lowering effects of beta blockers.
- 2. Concurrent use of beta blockers and calcium channel blockers or
- disopyramide can lead to heart failure or very low blood pressure.
- 3. Cimetidine and oral contraceptives (birth control pills) can increase
- the blood concentrations of metoprolol, which can result in greater side
- effects.
- 4. Alcohol, barbiturates, and rifampin can decrease the effectiveness of
- metoprolol.
- 5. Side effects may be increased if beta blockers are taken with
- clonidine, digoxin, epinephrine, phenylephrine, phenylpropanolamine,
- phenothiazine tranquilizers, prazosin, or monoamine oxidase (MAO) inhibitors.
- At least 14 days should separate the use of a beta blocker and the use of an
- MAO inhibitor.
- 6. Beta blockers may antagonize (work against) the effects of
- theophylline, aminophylline, albuterol, isoproterenol, metaproterenol, and
- terbutaline.
- 7. Beta blockers can also interact with insulin or oral antidiabetic
- agents, raising or lowering blood sugar levels and masking the symptoms of low
- blood sugar.
- 8. The action of beta blockers may be increased if they are used with
- chlorpromazine, furosemide, or hydralazine, which may have a negative effect.
- BE SURE TO TELL YOUR DOCTOR about any medications you are currently
- taking, especially any listed above.
-
- WARNINGS
-
- * Tell your doctor if you have ever had unusual or allergic reactions to
- any drugs, especially to metoprolol or any other beta blocker (acebutolol,
- atenolol, carteolol, esmolol, labetalol, nadolol, penbutolol, pindolol,
- propranolol, or timolol).
- * Tell your doctor if you now have or have ever had allergies, asthma,
- hay fever, eczema, slow heartbeat, bronchitis, diabetes mellitus, emphysema,
- heart or blood vessel disease, kidney disease, liver disease, thyroid disease,
- or poor circulation in the fingers or toes.
- * You may want to check your pulse while taking this medication. If your
- pulse is much slower than your usual rate (or if it is less than 50 beats per
- minute), check with your doctor. A pulse rate that is too slow may cause
- circulation problems.
- * This medicine may affect your body's response to exercise. Make sure
- you discuss with your doctor a safe amount of exercise for your medical
- condition.
- * It is important that you do not stop taking this medicine without first
- checking with your doctor. Some conditions may become worse when the medicine
- is stopped suddenly, and the danger of a heart attack is increased in some
- patients. Your doctor may want you to reduce gradually the amount of medicine
- you take before stopping completely to minimize the potential risks. Make
- sure that you have enough medicine on hand to last through vacations,
- holidays, and weekends.
- * Before having surgery or any other medical or dental treatment, tell
- your doctor or dentist that you are taking metoprolol. Often, this medication
- will be discontinued 48 hours prior to any major surgery.
- * Metoprolol can cause dizziness, drowsiness, light-headedness, or
- decreased alertness. Exercise caution while driving a car or using any
- potentially dangerous machinery.
- * While taking this medicine, do not use any over-the-counter
- (nonprescription) allergy, asthma, cough, cold, sinus, or diet preparation
- without first checking with your pharmacist or doctor. Some of these
- medicines can result in high blood pressure when taken at the same time as a
- beta blocker.
- * Be sure to tell your doctor if you are pregnant. Animal studies have
- shown that some beta blockers, when used in very high doses, can cause
- problems in pregnancy. Adequate studies have not been conducted in humans,
- but there has been some association between beta blockers used during
- pregnancy and low birth weight, as well as breathing problems and slow heart
- rate in newborn infants. However, other reports have shown no effects on
- newborn infants. Also, tell your doctor if you are breast-feeding an infant.
- Although this medicine has not been shown to cause problems in breast-fed
- infants, some of the medicine may pass into breast milk, so caution is
- warranted.
