This whole incident hasn't done much to shake my impression that US doctors are interested first and foremost in making sure they get their "cut" on every prescription, even when the drug is relatively innocuous.
Like fine, we can have this discussion about chloroquine. It's behind-the-counter in the UK, so on par with sudafed in terms of access control, and OTC in a lot of countries that actually have to deal with malaria directly. But the same argument gets applied to stuff like oral contraceptives, which are straight-up OTC in a lot of countries too, and can simply be discontinued if you notice symptoms.
At the same time, we allow drugs with insanely narrow theraputic ranges like tylenol/acetaminophen/paracetamol (seriously, almost as bad as the chloroquine people are freaking out about, a normal dose is 1-4g and a lethal dose can be as low as 5g) to be sold OTC here with no questions whatsoever. We allow combination products despite obvious risks for multiple dosing, we allow combination products to "dissuade addicts" from abusing opiods (like any addict has ever been dissuaded by a risk bodily harm). And doctors don't make a peep about that, because they're not accustomed to getting their cut on that one.
That's also why the AMA resists nurse practitioners so hard. The truth is, a lot of those drugs really should be "behind the counter", a pharmacist should simply have to give you a quick rundown of possible symptoms and what to do if you notice them (discontinue and see a doctor or go to a hospital depending on urgency, same as you would do with a doctor-prescribed drug), but doctors won't allow that because they wouldn't get their cut, so we just call them "nurse practitioners" instead.
US doctors really like playing gatekeeper, to a much greater extent than other countries (where coincidentally, money doesn't come into the picture as much).
