Should an 84 year old man be taking all of these medications at the same time? Bydureon 2mg, Plavix 75mg, Losartan Potassium , Flomax .04, Metformin HCL 1000mg, Exelon 4.5 mg capsule, and Lipitor? He is having a lot of dizzy spells,dry coughing, confusion, memory loss, agitation, back pain, diarrhea, joint pain, and many other things. He lives alone and has no one there with him when he has dizzy spells. He still drives but shouldn t!!! He is my boss and I am worried about him! He is a retired lawyer but he insists on going to the office each day because he has a lot of real estate to manage. Thank you, Kelly
