Generic Name: betaxolol (be-TAX-oh-lol)
Brand Name: Kerlone
Do not suddenly stop taking betaxolol. Sharp chest pain, irregular heartbeat, and sometimes heart attack may occur if you suddenly stop betaxolol. The risk may be greater if you have certain types of heart disease. Your doctor should slowly lower your dose over several weeks if you need to stop taking it. This should be done even if you only take betaxolol for high blood pressure. Heart disease is common and you may not know you have it. Limit physical activity while you are lowering your dose. If new or worsened chest pain or other heart problems occur, contact your doctor right away. You may need to start taking betaxolol again.
Betaxolol is used for:
Treating high blood pressure. It may be used alone or with other medicines. It may also be used for other conditions as determined by your doctor.
Betaxolol is a beta-blocker. It works by slowing down the heart and decreasing the amount of blood it pumps out. This helps to decrease blood pressure, helps the heart pump more efficiently, and reduces the workload on the heart.
Do NOT use betaxolol if:
- you are allergic to any ingredient in betaxolol
- you have greater than first-degree heart block, shock caused by severe heart problems, uncontrolled heart failure, or a very slow heartbeat
Contact your doctor or health care provider right away if any of these apply to you.
Before using betaxolol:
Some medical conditions may interact with betaxolol. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:
- if you are pregnant, planning to become pregnant, or are breast-feeding
- if you are taking any prescription or nonprescription medicine (eg, medicines to treat colds or congestion), herbal preparation, or dietary supplement
- if you have allergies to medicines, foods, or other substances or are taking medicine for allergies
- if you have or have ever had an adrenal gland tumor (pheochromocytoma), lung or breathing problems (eg, asthma, chronic obstructive pulmonary disease, chronic bronchitis, emphysema), psoriasis, glaucoma or increased pressure in the eye, diabetes, kidney or liver problems, low blood sugar, or overactive thyroid
- if you have a history of chest pain or angina, heart problems (eg, heart failure, slow or irregular heartbeat, heart attack), low blood pressure, blood circulation problems, or blood vessel problems (including those in the brain or heart)
- if you are on dialysis or are scheduled to have surgery
Some MEDICINES MAY INTERACT with betaxolol. Tell your health care provider if you are taking any other medicines, especially any of the following:
- Antiarrhythmics (eg, amiodarone, disopyramide, flecainide), calcium channel blockers (eg, mibefradil, nifedipine, verapamil), digoxin, fingolimod, or mefloquine because the risk of side effects, such as slow or irregular heartbeat, heart failure, or very low blood pressure, may be increased
- Clonidine because high blood pressure may occur in some cases, especially if you suddenly stop taking clonidine while taking betaxolol
- Catecholamine-depleting agents (eg, reserpine) because they may increase the risk of betaxolol's side effects
- Indomethacin because it may decrease betaxolol's effectiveness
- Alfuzosin, insulin, or prazosin because the risk of their side effects may be increased by betaxolol
This may not be a complete list of all interactions that may occur. Ask your health care provider if betaxolol may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.
How to use betaxolol:

Important safety information:
- Betaxolol may cause drowsiness, dizziness, or light-headedness. These effects may be worse if you take it with alcohol or certain medicines. Use betaxolol with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
- Betaxolol may cause dizziness, light-headedness, or fainting; alcohol, hot weather, exercise, or fever may increase these effects. To prevent them, sit up or stand slowly, especially in the morning. Sit or lie down at the first sign of any of these effects.
- It may take 1 to 2 weeks for betaxolol to reach its full effect. Do NOT take more than the recommended dose or stop taking betaxolol without checking with your doctor.
- Do not suddenly stop taking betaxolol without first checking with your doctor. If your doctor decides you should no longer use betaxolol, you will need to stop betaxolol gradually according to your doctor's instructions.
- Patients who take medicine for high blood pressure often feel tired or run down for a few weeks after starting treatment. Be sure to take your medicine even if you may not feel "normal." Tell your doctor if you develop any new symptoms.
- Betaxolol may mask certain signs of overactive thyroid (eg, fast heartbeat). If you have or may have an overactive thyroid, do not suddenly stop taking betaxolol. Suddenly stopping betaxolol could worsen your condition. Discuss any questions or concerns with your doctor.
- Diabetes patients - Betaxolol may affect your blood sugar. It may also hide signs of low blood sugar, such as a rapid heartbeat. Be sure to watch for other signs of low blood sugar. Low blood sugar may make you anxious, sweaty, weak, dizzy, drowsy, or faint. It may also make your vision change; give you a headache, chills, or tremors; or make you hungrier. Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.
- Tell your doctor or dentist that you take betaxolol before you receive any medical or dental care, emergency care, or surgery.
- If you have a history of any severe allergic reaction, talk with your doctor. You may be at risk of an even more severe allergic reaction if you come into contact with the substance that caused your allergy. Some medicines used to treat severe allergies may also not work as well while you are using betaxolol.
- If your doctor has instructed you to check your blood pressure and heart rate regularly, be sure to do so.
- Betaxolol may interfere with the glaucoma screening test. Be sure your doctor and lab personnel know you are taking betaxolol.
- Lab tests, including blood pressure, may be performed while you use betaxolol. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
- Use betaxolol with caution in the ELDERLY; they may be more sensitive to its effects, especially slow heartbeat.
- Betaxolol should be used with extreme caution in CHILDREN; safety and effectiveness in children have not been confirmed.
- PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using betaxolol while you are pregnant.
