@ers12345 I’ve been on it for 10mos for very similar reasons, I’m on 1000mg twice a day. I was diagnosed with Antisynthatase PL7 and dermamyositis and it was attacking my lungs. It turned into pneumonia before knew what was going on and it got pretty scary there for a few months. Honestly I was nervous to go on cell cept as well but, it turns out it’s not that bad. Because of the immune suppression I am more intentional about getting my vaccines, masking up when I get on a plane and wearing sunscreen. I also got a referral for Dermatologist and see them once a year to do a full body check(the melanoma risk). I get my monitoring labs every 3 mos and my numbers have all been in normal ranges. In fact, it was until I came down the prednisone that my labs started stabilizing. I will say the steroid withdrawal once I got below 5mg wasn’t pleasant. But it only lasted a day or two. I still travel , go outside(I do not sunbathe), and largely have been able to live a normal life. Wishing you all the best! I know starting a new med, especially with the warnings this one comes with can be scary but you got this!
