usually autoimmune liver disease comes and goes. You can check your liver enzymes one time and they may be normal, and then one month later they may be up and so forth.
Usually a low dose of azathioprine
(generic) is enough to keep the disease under control. Keep in mind that if you don't keep it under control (with normal liver enzymes), then the inflammation can progress to "cirrhosis" which when the liver is almost non-functioning and requires a liver transplantation
Make sure you go to a liver specialist for treatment recommendations. You may even need a liver biopsy
