A very valid point there J.V.
I know someone who (it was strongly implied) only went into remission with his Luekemia due to being able to take drugs which the national health service would not have given / been able to afford.
If not that, at the very least his side effects were far more bearable due to 'private' treatments.
I know that with my Bi-Polar , I seem to have been always offered the cheapest options until I refused to take them due to very bad side effects. At that point relatively expensive alternatives were suddenly offered rather than the hospital losing face and possibly losing a patient !
I have lost count of the times I have been physically or mentally been made to feel dire due to being given cheap generics as 1st, 2nd and 3rd choice.
It took a lot of research and persuasion on my part to choose what would probably suit better and then the process of putting up the evidence so I could be allowed a better suited spectrum of drugs etc.
Thankfully In the longer term, even the costliest drugs become available as cheaper generics due to the expiry of patents etc.
Meanwhile I believe the point you raised to be very valid from my own experience.
