Brief Answer:
Yes it van cause fatigue . Slowing increase the dose as compared to previou

Detailed Answer:
Yes lopressor can cause weakness and fatigue and this would be particularly more at more than 70 years of age .
lopressor slows the heart pumping as an over all effect resulting in decreased blood supply to the exercising muscle , also decrease in heart rate more than required may cause weakness and the body wouldn't get enough blood supply .
However in heart condition the benefitial effects are far more than the fatigue it causes .
So discuss it with your doctor about the side effects , Best is to slowly up titrate dose do that the body gets accustomed to the new plateau.
Also discuss the alternatives with your doctor .
