- USES
-
- Propranolol is used to treat high blood pressure, angina pectoris (chest
- pain), and irregular heartbeats. It is also useful in preventing migraine
- headaches and preventing additional heart attacks in heart attack patients.
- Propranolol 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
-
- Propranolol 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.
- The extended-release capsules should be swallowed whole. Do not chew or
- crush them. Breaking the capsule releases the medication all at
- once--defeating the purpose of extended-release capsules.
- The oral solution should be measured with a specially designed 5-ml
- measuring spoon.
- The oral concentrated solution must be mixed in four ounces (1/2 cup) of
- water, juice, or soda before drinking. The cup should be refilled with more
- of the liquid, which must be drunk to ensure that the entire dose is taken.
- This form may also be mixed with applesauce or pudding.
- It is important to remember that propranolol does not cure high blood
- pressure, but it will help control the condition as long as you continue to
- take it.
- Try not to miss any doses of this medicine. If you do miss a dose, take
- the missed dose as soon as possible, unless it 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) of your next scheduled dose. In
- that case, do not take the missed dose at all; just return to your regular
- dosing schedule. Do not double the next dose of the medication.
-
- SIDE EFFECTS
-
- Minor.
-
- Anxiety; 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 as your body adjusts to the medicine.
- To relieve constipation, increase the amount of fiber in your diet (fresh
- fruits and vegetables, salads, bran, and whole-grain breads) and drink more
- water (unless your doctor directs you to do otherwise).
- If you are extra-sensitive to the cold, be sure to dress warmly during
- cold weather.
- Plain, nonmedicated eye drops (artificial tears) may help to relieve eye
- dryness.
- Sucking on ice chips or chewing sugarless gum helps to relieve mouth and
- 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, cold hands or feet (due to decreased blood
- circulation to skin, fingers, and toes), confusion, depression, dizziness,
- hair loss, hallucinations, light-headedness, nightmares, numbness or tingling
- of the fingers or toes, rapid weight gain (three to five pounds within a
- week), reduced alertness, swelling, sore throat and fever, skin rash, or
- unusual bleeding or bruising.
-
- INTERACTIONS
-
- Propranolol interacts with a number of other types of medications:
- 1. Indomethacin, aspirin, or other salicylates lessen the
- blood-pressure-lowering effects of beta blockers.
- 2. Concurrent use of beta blockers and calcium channel blockers
- (diltiazem, nifedipine, or verapamil) 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 propranolol, which can result in greater side
- effects.
- 4. Side effects may also be increased when beta blockers are taken with
- clonidine, digoxin, epinephrine, phenylephrine, phenylpropanolamine,
- phenothiazine tranquilizers, prazosin, reserpine, or monoamine oxidase (MAO)
- inhibitors. At least 14 days should separate the use of a beta blocker and an
- MAO inhibitor.
- 5. Barbiturates, alcohol, and rifampin can increase the breakdown of
- propranolol in the body, which can lead to a decrease in its effectiveness.
- 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 or masking the symptoms of low
- blood sugar.
- 8. The action of beta blockers may be excessively increased if they are
- used with chlorpromazine, furosemide, or hydralazine.
- BE SURE TO TELL YOUR DOCTOR about any medications you are currently
- taking, especially any of those listed above.

- WARNINGS
-
- * Before starting to take this medication, it is important to tell your
- doctor if you have ever had unusual or allergic reactions to any beta blocker
- (acebutolol, atenolol, betaxolol, carteolol, esmolol, labetalol, metoprolol,
- nadolol, penbutolol, pindolol, propranolol, or timolol).
- * Tell your doctor if you now have or if you 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 ask your doctor what an appropriate amount of exercise would be for you,
- taking into account 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 gradually reduce the amount of medicine
- you take before stopping completely. 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 physician or dentist that you are taking this medicine. Often, this
- medication will be discontinued 48 hours prior to any major surgery.
- * Propranolol can cause dizziness, drowsiness, light-headedness, and
- decreased alertness. Use caution while driving a car or operating dangerous
- machinery. Be especially careful when going up or down stairs.
- * While taking this medicine, do not use any over-the-counter
- (nonprescription) allergy, asthma, cough, cold, sinus, or diet preparations
- without first checking with your pharmacist or doctor. The combination of
- these medicines with a beta blocker can result in high blood pressure.
- * Be sure to tell your doctor if you are pregnant. Animal studies have
- shown that some beta blockers can cause problems in pregnancy when used at
- very high doses. Adequate studies have not been done in humans, but there has
- been some association between use of beta blockers 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 in 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.
