Is there any specific diet for IGG4? I was recently diagnosed with the disease in Nov, 2014. I started on a high dose of 60 mg of Prednisone and 50mg of Azathioprine. I now take 150mg of Azathioprine and 20mg of Prednisone. My doctor has tried to wean me down off the Prednisone. Today my labs did not look well, so I am staying on my regimen 20 Prednisone and 150mg Azathioprine. My fear was as soon as I came off the Prednisone my disease would flair back up. My doctors are going to try Rutuxin at some point. With my disease comes itching. I use to itch all over my body everywhere Hydroxyzine 50mg helped I am now back to itching just was started on Sertraline HCL 50mg. I am also taking Trazodone 100MG tab for the itching and sleep. This disease came out of nowhere I am trying very hard to get use to this way of life.
