I've been to the citizens Advice Bureau. Because it is NHS they refer to PALS. PALS will hum and haw because they usually advocate for NHS patients who are dissatisfied with treatment that they have already received which they have a complaint about. If the complaint is about treatment not received, using drugs that are not NHS supplied, then good luck with that. Somebody might have some luck with this process but I didn't.
The UK is famously a multi-cultural society. Indians, Pakistanis, Jamaicans, Arabs, East Europeans, Chinese, etc., they are all here. They mingle and they also have their own core communities. Handouts of any kind are not part of their culture. They expect to pay and are pleasantly surprised if they don't have to.
Anyway, as to how many UK patients will go for the generics, only time will tell. Most of them are currently being disabused of their belief that they will get access to free treatment for their hepc before they die. As time goes on, disillusionment sets in and the penny drops, what will they do then?
The threat of death transcends all cultural norms. I saw an entry a while ago which moved me greatly. This person said something like, and I hope they don't mind if I recall it, "I will crawl over broken glass to get my meds"
Do you really think that a person who feels like that is going to sit complacently watching the NHS fiddling while Rome burns.
