Hi carophie04 I have over the last 5 or 6 years had a totally different experience of doctors and offers of treatments some being extremely expensive as in the case of pain killing meds for my arthritis, one drug tried was £880 a month but I had side effects so it was changed, at my request, and another drug prescribed, it took 2 or 3 years but I now have a very effective pain relief med that again is not cheap.
No one will argue that the NHS reforms have caused problems especially with things like bg test strip prescriptions but any drug that is approved can be prescribed by your GP if she/he thinks it appropriate.
Ramipril is offered to many diabetics not because it is cheaper than some other BP drugs but because it is proven to help guard against diabetic kidney damage, now perhaps your GP didnt explain that to you but it sounds as though he/she had your best interests at heart (no pun intended) when switching your meds. Of cause it is a shame you had some side effects with it but thats not to say it was not worth trying as kidney damage is common in diabetics.
Despite successive governments lack of investment into the NHS I still believe that doctors still have our best interests at heart, doctors are not accountants and if they think a particular treatment is beneficial a patient they will prescribe it providing it is an approved treatment in their trusts area. Post code lottery? Yes, but again thats not the doctors fault is it, thats whats been put in place by successive governments.
