The issue isn't even just the prescription.
It's that your health care system the doctor is in builds a few extra hurdles. I've talked to my (non-tele) doctor about GLP-1. I've tried losing weight before, with her, there's a long history.
To get approval, between the hospital my doc is in and the insurance, I need to:
1) Have a BMI of >30. Since it's only 29.5, I get to stuff my face if I want to lose weight.
2) Have six sessions with a nutritionist. Which are massively useless, their advice is roughly equivalent to reading Cosmopolitan. I know because I had prior conversations, and they're documented. But still, gotta do it again.
3) Do six months on Weight Watchers. Which is one massive scam leading you right to disordered eating. Also, I've tried for years to lose weight via diet changes, documented and talked through with my doc.
4) Before I can get tirzepatide, I have to get semaglutide for three months to see if it works. Never mind there's study over study over study showing it's slightly less effective and has massively more side effects.
Or I can just cough up the cash directly and buy from Eli Lilly, if somebody signs that receipt.
I'm fortunate enough I could afford that, so I did. (After a second consultation with my family's doctor back home - both they and my doctor agreed it was appropriate, so it's not just a case of "wanting is enough")
And after six months, my weight was in a much better region, lipid panels were much improved, other related biomarkers looked better as well - exactly as numerous studies and my doctors said one could expect.
So, as long as I cough up enough money, sure, I can bypass all the hoops. My health didn't enter the equation, just screw the poors (whose treatment for worse outcomes because they couldn't get access will cost a whole lot more than GLP-1 would've cost).
So, fuck the "prescription hurdle" and the medical system in the US with a hot white glowing iron rod right up the ass.
As for "these are not drugs that anyone can safely take without guidance", that's not really true either.
They're neither hard to take - "inject one vial once a week into the flabby part" isn't rocket science - nor does it cause massive health risks by itself. (And the hazard ratios for diabetes 2 and cardio events are so spectacularly low that they dwarf the other risks)
Yes, talking to a doc is a good idea. No, the current gatekeeping is in no way necessary.
