I'm not sure if this is something I should get checked out. I am taking Diovan 80/12 for several years without problems. Lately, I'm dizzy almost every time I stand. I'm searching for words, I searched for even an hour or two before. It is happening 20+ times a day. Also, I can feel my blood pumping in my arms. I have hypothroid and fibro. See a doctor on a regular basis. My B12 was low so he has me taking 2000mcg a day. I also take lipitor 10mg, celebrex 400mg, and Effexor 150 mg. I recently started on weight watchers. My BMI is about 32. Is the dizzyness and lack of speech anything to worry about?
