PVC is almost certainly correct: There's little way that a dozen, or more, prescription meds, over time, will not cause more problems, somewhere down the line, due to unforeseen interactions. Find a group of docs who are not pill pushers.
I have a pcp who's a pill pusher. I know he is, so I'm on guard, and rarely go through with anything he prescribes. One prescription he wrote was for an allergy med that has so many contraindications I knew there was zero chance I'd take it. Both my pharmacist and allergist asked if I ever took it, and were relieved when I said I hadn't. Another time, he prescribed a mega mega dose of a vitamin, that was so high it required a prescription. When i read up on it, I found that it could have been toxic, over time! I like bs'ing with the guy, so I keep him. He's actually a good guy for swapping the stuff with. As long as I am on guard, things are cool. I use him to confirm any health issues I already know I have before I ever see him for the same.
