Daddy's meds are causing dizziness and tiredness. Any advice?

He is a fall risk, so this is a very bad thing. He has an appointment with his new primary care later this week. I may get in trouble for taking him off the meds that are causing problems, but it makes no sense to keep him on meds that contribute to his unsteadiness. He has had PT and absolutely will NOT exercise. He is non compliant in many ways, so we do the best we can.
