Mr B is under treatment with low-dose atenolol for his hypertension. His BP was about 145/95 mm Hg at his last three visits. In addition, Mr B complains of fatigue. How will you manage Mr B's hypertension?
Extra info: Obviously the dose of atenolol is not high enough to control Mr B's hypertension. On the other hand, the dose cannot be increased, because Mr B's fatigue is an adverse effect of atenolol.
