TSRH. for a number of reasons, docs just are not as well informed as they probably were way back when...and if they really are promoting the pharm's drug-of-the-day, they'll likely tell you what they've just been told, assuming the pharm rep knows what they're talking about...which they probably do...up to a certain point -- because the drug companies are telling them the things they need simply to push the stuff.
I'm going to disagree. At least not my docs. The vast majority of decent docs have associations they go to and are members of. They are affiliated with a few hospitals and are friends with the docs with the same specialty in the same area. They exchange vast amounts of info regularly, like, "yeah, the drug reps are pushing this heartburn med anyone have any results?" Just like we're all exchanging info on here, they have far better and more informed resources than a cute drug rep. If you really think your doc is just pushing the most recent fix you need to change docs.
