- USES
-
- This drug is prescribed to treat high blood pressure.
- Hydrochlorothiazide is a diuretic (water pill), which reduces fluid
- accumulation in the body by increasing the elimination of salt and water
- through the kidneys. Propranolol belongs to a group of drugs known as
- beta-adrenergic blocking agents or, more commonly, beta blockers. They work
- by controlling nerve impulses along certain nerve pathways.
-
- TREATMENT
-
- This medication 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. Avoid taking a
- dose after 6:00 p.m.; otherwise, you may have to get up during the night to
- urinate.
- If you miss a dose of this medication, take the missed dose as soon as
- possible, unless it is almost time for your next dose. In that case, do not
- take the missed dose at all; just wait until the next scheduled dose. Do not
- double the dose.
- Propranolol and hydrochlorothiazide combination does not cure high blood
- pressure, but it will help control the condition as long as you continue to
- take it.
-
- SIDE EFFECTS
-
- Minor.
-
- Anxiety, constipation, cramps, decreased sexual ability, diarrhea,
- difficulty in sleeping, drowsiness, dizziness, dryness of the eyes and skin,
- headache, heartburn, loss of appetite, nervousness, stomach discomfort,
- restlessness, or tiredness. These side effects should disappear as your body
- adjusts to the medication.
- Hydrochlorothiazide can cause increased sensitivity to sunlight. Avoid
- prolonged exposure to sunlight and sunlamps. Wear protective clothing and use
- sunscreen.
- If you become 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) unless your
- doctor directs you to do otherwise.
- Plain, nonmedicated eye drops (artificial tears) may help to relieve eye
- dryness.
- To avoid dizziness or light-headedness when you stand, contract and relax
- the muscles of your legs for a few moments before rising from a sitting or
- reclining position. Do this by pushing one foot against the floor while
- raising the other foot slightly, alternating feet so that you are "pumping"
- your legs in a pedaling motion.
-
- Major.
-
- Tell your doctor about any side effects that are persistent or
- particularly bothersome. IT IS ESPECIALLY IMPORTANT TO TELL YOUR DOCTOR about
- blurred vision, cold hands and feet (due to decreased blood circulation to
- skin, fingers, and toes), confusion, depression, difficulty in breathing, dry
- mouth, excessive thirst, excessive weakness, fever, hair loss, hallucinations,
- itching, joint pain, mood changes, muscle spasms, nausea, nightmares, numbness
- or tingling in the fingers or toes, palpitations, rapid weight gain (three to
- five pounds within a week), reduced alertness, skin rash, sore throat,
- swelling, unusual bleeding or bruising, vomiting, or yellowing of the eyes or
- skin.
-
- INTERACTIONS
-
- This medicine interacts with other types of drugs:
- 1. Indomethacin, aspirin, and other salicylates may decrease the
- blood-pressure-lowering effects of beta blockers.
- 2. Use of propranolol and calcium channel blockers (diltiazem,
- nifedipine, or verapamil) or disopyramide can lead to heart failure or very
- low blood pressure.
- 3. Cimetidine or oral contraceptives (birth control pills) can increase
- the blood levels of propranolol, which can result in greater side effects.
- Side effects may also be increased when propranolol is 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 propranolol and an MAO inhibitor.
- 4. Barbiturates, alcohol, and rifampin can increase the breakdown of
- propranolol, which can lead to a decrease in its effectiveness.
- 5. The action of beta blockers may be increased if they are used with
- chlorpromazine, furosemide, or hydralazine, which may have a negative effect.
- 6. Propranolol can antagonize (act against) the effects of theophylline,
- aminophylline, albuterol, isoproterenol, metaproterenol, and terbutaline.
- 7. Propranolol can also interact with insulin and oral antidiabetic
- agents, raising or lowering blood sugar levels and masking the symptoms of low
- blood sugar.
- 8. Hydrochlorothiazide can decrease the effectiveness of oral
- anticoagulants (blood thinners, such as warfarin), antigout medications, and
- methenamine.
- 9. Antihypertensive medications may increase the blood-pressure-lowering
- effects of propranolol and hydrochlorothiazide combination, which can be
- dangerous.
- 10. Cholestyramine and colestipol can decrease the absorption of
- hydrochlorothiazide from the gastrointestinal tract; therefore,
- hydrochlorothiazide should be taken one hour before or four hours after a dose
- of cholestyramine or colestipol if one of these medications has also been
- prescribed for you.
- 11. Hydrochlorothiazide may increase the side effects of amphotericin B,
- calcium, cortisone and cortisone-like steroids (such as dexamethasone,
- hydrocortisone, prednisone, and prednisolone), digoxin, digitoxin, lithium,
- quinidine, sulfonamide antibiotics, and vitamin D.
- TELL YOUR DOCTOR about any medications you are currently taking,
- especially any of those listed above.

- WARNINGS
-
- * Tell your doctor about unusual or allergic reactions you have had to
- medications, especially to propranolol or any other beta blocker (such as
- acebutolol, atenolol, betaxolol, carteolol, esmolol, labetalol, metoprolol,
- nadolol, penbutolol, pindolol, and timolol), to hydrochlorothiazide or other
- diuretics (such as bendroflumethiazide, benzthiazide, chlorothiazide,
- chlorthalidone, cyclothiazide, hydroflumethiazide methyclothiazide,
- metolazone, polythiazide, quinethazone, trichlormethiazide, and furosemide),
- or to any sulfa drug (oral antidiabetic medication and sulfonamide
- antibiotic).
- * Tell your doctor if you have ever had asthma, diabetes mellitus, heart
- disease, gout, kidney disease or problems with urination, liver disease,
- pancreatitis, systemic lupus erythematosus, thyroid disease, or poor
- circulation in the fingers or toes.
- * Hydrochlorothiazide can cause potassium loss. Signs of potassium loss
- include dry mouth, thirst, weakness, muscle pain or cramps, nausea, and
- vomiting. If you experience any of these symptoms, call your doctor. To help
- prevent this problem, your doctor may have blood tests performed periodically
- to monitor your potassium levels. To help avoid potassium loss, take this
- medication with a glass of fresh or frozen orange juice or cranberry juice, or
- eat a banana every day. The use of a salt substitute also helps to prevent
- potassium loss. Do not change your diet, however, until you discuss it with
- your doctor. Too much potassium may also be dangerous.
- * While you are taking this medication, limit your intake of alcohol, in
- order to prevent dizziness and light-headedness.
- * Do not take any over-the-counter medications for weight control or for
- allergy, asthma, cough, cold, or sinus problems unless you first check with
- your doctor.
- * To prevent severe water loss (dehydration) while taking this
- medication, check with your doctor if you have any illness that causes severe
- or continuous nausea, vomiting, or diarrhea.
- * This medication can raise blood sugar levels in diabetic patients.
- Blood sugar levels should be monitored carefully with blood or urine tests
- when this medication is being taken.
- * 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.
- * Propranolol can 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.
- * Before having surgery or any other medical or dental treatment, tell
- your doctor or dentist that you are taking this medicine. Often, this
- medication will be discontinued 48 hours prior to any major surgery.
- * This medication can cause dizziness, drowsiness, light-headedness, or
- decreased alertness. Therefore, you must exercise caution while driving a car
- or operating potentially dangerous machinery.
- * It is important that you do not stop taking this medicine unless you
- first check with your doctor. Some conditions worsen when this medicine is
- stopped suddenly, and the danger of a heart attack is increased in some
- patients. Your doctor may therefore 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.
- * A doctor does not usually prescribe a "fixed-dose" drug like this as
- the first choice in the treatment of high blood pressure. Usually, the
- patient first receives each ingredient singly. If there is an adequate
- response to the fixed dose contained in this product, it can then be
- substituted. The advantage of a combination product is increased convenience
- and (often) decreased cost.
- * 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 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 such effects in newborn
- infants. Hydrochlorothiazide has been associated with jaundice, blood
- problems, and low potassium in the newborn. Also, tell your doctor if you are
- breast-feeding an infant. Although problems in humans have not been reported,
- small amounts of propranolol and hydrochlorothiazide pass into breast milk, so
- caution is warranted.
