I had been on the original Coversyl for 4 years. After one prescription I started to suffer muscle pain in my upper thighs, an inspection of the box revealed I had been prescribed generic Perindopril not the original,a very clever copy of the old box was the culprit. I changed back immediatley and the problem disappeared. Since then I was given the new Arginine salt, within a month the side effects returned and are getting worse in addition I am experiencing muscle pain at the back of my neck.
I am being changed to an entirely different ACE inhibitor despite the fact my GP believes they are the same product.
I have been conned for the convenience of the drug companies!
