In patients with existing slow heart rate (bradycardia) and heart block (defects in the electrical conduction of the heart), betaxolol can cause a dangerously slow heart rate and even shock. Betaxolol reduces the force of heart muscle contraction and can aggravate symptoms of heart failure. In patients with coronary artery disease, abruptly stopping betaxolol can suddenly worsen angina, and occasionally precipitate heart attacks. If it is necessary to discontinue betaxolol, its dosage should be reduced gradually over several weeks. Like all other beta-blockers, betaxolol can mask the early warning symptoms of low blood sugar (hypoglycemia) in people with diabetes and can increase or decrease blood sugar. Therefore, it should be used with caution in patients with diabetes.
