In the US, as others have noted, doctors play by the insurance and drug company rules and influence, I don't care how many times they all tell you they're above all that. In this country if a doctor says you need X medication, the insurance company can and DOES say nope, we don't think you need that. It's insane, there is literally no reason for that middle to even exist, but that's what $$$ buys you when the rules are made.
My next doc will get the info that I'm on Tirz ONLY if it's relevant to something specific, but I'm actively searching for the rare doc (had one for years until he retired) that does NOT think every patient has to report annually or semiannually because the rule books say so. I traditionally go the doc when blood is coming out of some place it isn't supposed to, a bone is poking at an odd angle, or something that used to work isn't anymore. I don't need a doc poking around in me anymore than that.
