I am an otherwise healthy, fit 50 year old male with mild hypertension (typical reading 140/95). Was put on Lisinopril following an atrial flutter episode. While my BP was lowered (typical reading 125/83), I experienced extreme fatigue and dizziness - felt horrible, like I had been poisoned. With my cardiologist's consent, after 2 weeks I stopped and switched to Cozaar. After 3 days, I feel vastly improved. BP readings are a little higher - 125/93 this AM. I do not know if Cozaar will ultimately have side effects, but cannot imagine they are worse than Lisinopril, at least for me.
