This is, in fact, a fiction and it must be stated as untrue. You have a right to your opinion but you don't have a right to others buying into this insane line of thought. The United States is a diverse place, with many differing points of view. Arguing that American political leaders should NOT insist on lowering medication costs for Americans is rich. Perhaps, UK political leaders should actually advocate for the British people and stop falsely blaming the Americans for their own abysmal failures.
As for warfarin, I do wish you luck with this medication. If it works for you then you should stick with it. The fact that you do not bleed freely while on a blood thinner is a bad sign, but I guess that you know what you're doing.
You said that warfarin is free. I would argue that free is a political discussion that is being incorrectly used here. You paid, over your entire lifetime, into the National Health Service. There is a reasonable expectation that, now their services are required, that you obtain the best treatment that exists. Getting old school medications or no medications at all from the service that you paid for is disgraceful.
I pay for my medical insurance. I upped the quality of service so, I pay more than others. Medical insurance is a standard benefit offered by employers. Most offer standard care for no cost to the employee as the employer wraps the cost into the benefit package. This is not different than your NHS. You paid for NHS, perhaps more than I paid for my medical insurance. I didn't start upping my medical insurance until a few years ago, so my entire life it has been just a employer supplied benefit.
When I started on Elequis I actually asked about warfarin as my father used it in the 1980s. The cardiologist explained the benefits and downsides of the old medications vs the newer generations of medications. I made the decision to use eliquis, not the physician. In the end, the fee that I pay for a 90 day supply of eliquis is $15. After I outlay a certain amount ($2000) all of my medical care is cost free to myself for the reminder of the year. I spent five days in the best hospital in Florida, in June, to have a new cardiorythm drug started. I had a private room, with shower, AC, a nice view of palm trees, parrots in the palms, cable TV, internet, three meals a day chosen by myself off a menu and this cost me zero out of my pocket as I maxed out my out of pocket expense in April. As much as one can enjoy a hospital, I enjoyed that experience. The nurses were wonderful. I watched the NBA finals and the first World Cup game, in my room with doctors and nurses. We had a grand time. Here's the best part, since I fulfilled my out of pocket expense in April, all of my medical care, pills, shots, visits, etc are cost free for me until January 1, 2027. So, that expensive eliquis costs me nothing until then. When I retire I will be on Medicare, which is quite similar to NHS except that I go to my private doctor's, hospitals etc. Medicare is a retirement benefit that, I paid for, my entire working life.
I'm half reading this thread because I am concerned to see others in bad situations and would like to help, if I can. I'm half reading this thread to understand how normal folks navigate the NHS for health care. The US has excellent health care for those who have jobs. Don't work, won't work, here illegally, well your health care will be enough and that's it. No comment on UK but in the US President Biden entered 20+ million illegal or spurious entrys of people into the US on top of the 20+ million earlier illegal aliens that were here. These people could not legally work so they had no health care. They were given places to stay and credit cards to buy food. The results were massive public debts to support these people, a bogged down health system, young people could not buy or rent a place as there was none to be found. Literally, out of 350 million people in the US 40-50 were illegally here and on the take. These same folks felt no need to assimilate to American culture as their needs were being taking care of by the US government. I'm not saying that UK has a similar problem.....
