Could Atenolol And Diovan Be The Cause For Dizziness?

I am a 61 year old, african american female. I am over weight. I take Atenolol 25 mg per day and Diovan Hzt 160/25 once per day. I am having bouts of dizziness, they are not debiltating but are bothersome and at times scary. I l know that the possible side effects of both meds could cause dizziness. Is there an alternative to this dilemma that I find myself in?
