What is the dosage for betaxolol?
Betaxolol usually is taken once daily. The optimal dose varies among patients. The recommended dose range is 5-20 mg daily.
Which drugs or supplements interact with betaxolol?
The blood pressure-lowering effects of betaxolol add to the blood pressure-lowering effects of other drugs. For this reason, combinations of betaxolol and other blood pressure-lowering drugs often are used to treat persons with high blood pressure.
When used in combination with diltiazem (Cardizem; Tiazac; Dilacor), verapamil (Calan; Isoptin; Verelan; Covera), amiodarone (Cordarone), or digoxin (Lanoxin), betaxolol or other beta-blockers, can cause complete block of the heart's electrical system causing serious abnormal heart rhythms.
Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (Motrin, Advil), naproxen (Naprosyn, Anaprox, Aleve), can reduce the blood pressure lowering effects of beta-blockers such as betaxolol.
