- ------------------------------------------------------------------------------
-
- BRAND NAME (Manufacturer)
-
- Kerlone (Searle)
-
- TYPE OF DRUG
-
- Beta-adrenergic blocking agent
-
- INGREDIENT
-
- betaxolol
-
- DOSAGE FORM
-
- Tablets (10 mg and 20 mg)
-
- STORAGE
-
- Betaxolol should be stored at room temperature in a tightly closed
- container.
-
- USES
-
- Betaxolol is prescribed for the treatment of high blood pressure.
- Betaxolol belongs to a group of medicines known as beta-adrenergic blocking
- agents or, more commonly, beta blockers. These drugs work by controlling
- impulses along certain nerve pathways. This results in a decreased workload
- for the heart.
-
- TREATMENT
-
- Betaxolol can be taken with a glass of water, with meals, immediately
- following meals, or on an empty stomach, depending on your doctor's
- instructions. It is important that you try to take the medication at the same
- time(s) each day.
- Try not to miss any doses of this medication. 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 medication
- only once a day) or within four hours (if you are taking this medication more
- than once a day), do not take the missed dose at all; just return to your
- regular dosing schedule. Do not double the next dose of the medication.
- It is important to remember that betaxolol does not cure high blood
- pressure.
-
- SIDE EFFECTS
-
- Minor.
-
- Decreased sexual ability, diarrhea, fatigue, headache, indigestion, or
- nausea. These side effects should diminish as your body adjusts to the
- medication.
-
- 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 the skin, fingers, and toes; confusion; dizziness; fever and
- sore throat; hair loss; hallucinations; light-headedness; mental depression;
- nightmares; reduced alertness; skin rash; swelling of the ankles, feet, or
- lower legs; or unusual bleeding or bruising.
-
- INTERACTIONS
-
- Betaxolol interacts with a number of other medications:
- 1. Indomethacin, other nonsteroidal anti-inflammatory agents, aspirin, or
- other salicylates may decrease the blood-pressure-lowering effects of beta
- blockers.
- 2. Calcium channel blockers (nifedipine, verapamil, and diltiazem) may be
- used with beta blockers such as betaxolol unless the patient has heart
- trouble. Very low blood pressure and heart failure have been observed in
- patients with impaired heart function who take beta blockers.
- 3. Side effects may also be increased if beta blockers are taken with
- epinephrine, phenylephrine, phenylpropanolamine, phenothiazine tranquilizers,
- reserpine, clonidine, 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.
- 4. Beta blockers may antagonize (work against) the effects of
- theophylline, aminophylline, albuterol, isoproterenol, metaproterenol, and
- terbutaline.
- 5. Beta blockers can also interact with insulin or oral antidiabetic
- agents--raising or lowering blood sugar levels or masking symptoms of low
- blood sugar.
- 6. The action of beta blockers may be increased if they are used with
- furosemide or hydralazine, which could have a negative effect.
- 7. Alcohol, barbiturates, and rifampin can decrease blood concentrations
- of this drug, which can result in a decrease in effectiveness.
- 8. If you are on both betaxolol and clonidine, and both of these
- medications are to be discontinued, it is recommended that the betaxolol be
- tapered off over several days before the gradual reduction of clonidine.
- 9. In patients who have congestive heart failure treated with digitalis
- glycosides (for example, digoxin or digitoxin), caution should be used as both
- betaxolol and digitalis products may slow heart conduction.
- Before starting to take betaxolol, BE SURE TO TELL YOUR DOCTOR about any
- medications you are already taking, especially any of the medications listed
- above.
-
- WARNINGS
-
- * Tell your doctor about any unusual or allergic reactions you have had
- to any medications, especially to betaxolol or any other beta blocker
- (acebutolol, atenolol, carteolol, esmolol, labetalol, metoprolol, nadolol,
- penbutolol, pindolol, propranolol, and timolol).
- * Tell your doctor if you now have or if you have ever had asthma,
- bronchitis, diabetes mellitus, heart block, heart failure, kidney disease,
- liver disease, peripheral vascular disease (poor circulation in the fingers or
- toes), severe bradycardia (slowed heart rate), or thyroid disease.
- * Betaxolol therapy may increase the risk of cardiac failure in some
- patients. Report any abnormal heart function to your doctor.
- * Patients with severe bronchospastic disease (such as asthma) should, in
- general, not receive beta blockers. Inform your physician if you experience
- breathing difficulties.
- * In diabetics, betaxolol may block some of the warning signs of low
- blood sugar (hypoglycemia), such as rapid pulse rate, but not others, such as
- dizziness or sweating.
- * You may want to check your pulse while taking this drug. 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 that is too slow may cause
- circulation problems.
- * This medication may affect your body's response to exercise. Ask your
- doctor what an appropriate amount of exercise would be for you.
- * It is important that you do not stop taking this drug, without first
- checking with your doctor. Some conditions such as angina pectoris may become
- worse when the drug 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 the drug you take before stopping completely. Make sure that you
- have enough medication on hand to last through vacations, and holidays.
- * Tell your doctor or dentist that you are taking this drug before having
- surgery or any other medical or dental treatment. Often, this medication will
- be discontinued 48 hours prior to any major surgery.
- * While taking this drug, do not use any over-the-counter
- (nonprescription) allergy, asthma, cough, cold, sinus, or diet preparations
- without first checking with your doctor or pharmacist. The combination of
- these medications with a beta blocker can result in high blood pressure.
- * Betaxolol may reduce intraocular pressure and give a misleading
- negative glaucoma test.
- * 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, breathing problems, and slow heart rate in the newborn.
- Also, tell your doctor if you are breast-feeding an infant. Although this
- medication has not been shown to cause problems in breast-fed infants, it may
- pass into breast milk, so caution is warranted.
- * The safety of this medication has not been established in children.
