It would be very difficult for you to go to the doctor's with your dad and ask the questions, Jeff, but that's what I had to do with my mom. I also found it necessary to make a chart of all the meds she was taking, the dosages, and pictures of what they look like and she keeps a copy, I keep a copy and the home keeps a copy. I bring it to each doctors appointment and we go over it. I refer to it every time I order refills for her. I also check the side effects and keep links to the med descriptions in the chart. I don't use the literature that comes with the meds because it's too generic. The side effects are the same for almost any medication. Of course, you know all about these meds from your work and personal life, so that wouldn't apply to you, but for me, who hardly ever even takes a painkiller, it's crucial.
