I have stopped the reformulated Coversyl, changing to Perindo which is now available. It has the same formulation as the original Coversyl: perindopril erbumine, not perindopril arginine. I heard from the pharmacist that Perindo was now available, but requires a replacement prescription. After a year of constant pain, within 4 days the severe myalgia stopped. And I'm not stiff and sore when I wake in the morning now. If anyone else is being crippled by muscle pain while on Coversyl, it may be a side effect.
