The third one sounds like what the doctors told me off, I am only eligible after my surgery is done, they literally doing it as a last resort, after dietician plan, after exercise plan and after surgery. The fourth sounds interesting but I guess only for diabetics?
Orlistat I don't think is generally considered a last resort drug as it's fairly benign, at least compared to surgery!
The 4th class, drugs like Dapagliflozin may be used as a last resort for weight loss but I don't really know much about them.
EDIT - You can buy orlistat from a pharmacist without a prescription so I don't think it's what the doctor is referring to, best to ask to clarify.
