nadolol (cont.)

In patients with existing slow heart rates (bradycardias) and heart blocks (defects in the electrical conduction of the heart), nadolol can cause dangerously slow heart rates, and even shock. Nadolol reduces the force of heart muscle contraction and can aggravate symptoms of heart failure. In patients with coronary artery disease, abruptly stopping nadolol can suddenly worsen angina and occasionally precipitate heart attacks. If it is necessary to discontinue nadolol, its dose should be reduced gradually over several weeks.
