Creatinine level can certainly brought down - Ayurvedic medicine is very helpful in doing this. You gotta be very careful with this though, make sure the Ayurvedic medicine do not contain any metals or other chemicals that can further compromise the kidneys.
Once the creatinine level hits 5, doctors usually start talking about dialysis. In allopathic medicine there is no cure for this disease. Dialysis or transplant is not a cure but a temporary relief for lifetime.
I have heard good stuff about Kundan Kidney Care centre in India, they offer Ayurvedic Kidney medicine - you may do a search on google.
