It also has duplicate entries for some drugs differing only by dosage and frequency as the doctors tinkered with the drugs for maximum effectiveness. Oddly, the online list does not have a way to filter for drugs that I am currently taking, which explains why the nurse asks me which drugs I'm currently taking. It's such a common question that I bring a printed list with me to appointments.
He doesn't have time to read the list, much less review any potential interaction problems. If you want to put your body in the hands of the medical profession and proclaim that they can do anything they wish, please continue on your present course. However, if you want some say in the matter, you'll need to do your own research and homework. Might as well start with the drug mess. Go thee unto various drug interaction sites and plug in everything that you're taking including OTC drugs, foods, and supplements.
