What is the most important information I should know about betaxolol (Kerlone)?

You should not take this medication if you are allergic to betaxolol or if you have a serious heart problem such as heart block, sick sinus syndrome, or slow heart rate, or severe or uncontrolled heart failure or pheochromocytoma.

Before taking betaxolol, tell your doctor if you have angina (chest pain), congestive heart failure, coronary artery disease, asthma, bronchitis, emphysema, diabetes, low blood pressure, depression, liver or kidney disease, a thyroid disorder, myasthenia gravis, or problems with circulation (such as Raynaud's syndrome).

If you need to have any type of surgery, tell the surgeon that you are using betaxolol. You may need to briefly stop using betaxolol before having surgery.

Do not skip doses or stop taking betaxolol without first talking to your doctor. Stopping suddenly may make your condition worse.

Betaxolol is only part of a complete program of treatment for hypertension that may also include diet, exercise, and weight control. Follow your diet, medication, and exercise routines very closely if you are being treated for hypertension.

Keep using this medicine as directed, even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your life.
