Thank you so much for your comments Dr. Anitha
Hi, carvedilol is a beta blocker and is indicated for the treatment of mild-to-severe chronic heart failure. Lisinopril is angiotensin converting enzyme (ACE) inhibitor, used to treat hypertension and heart failure, So, check with your doctor why the medications have been prescribed, it may not be for hypertension alone. Light headedness could be due to postural hypotension, wherein upon standing blood pooling occurs in the legs and the brain is deprived of adequate blood supply and oxygenation. This is more common in the elderly and in people with diabetes mellitus. So, don't worry and discuss these options with your doctor. Regards.
