re side effects immunosuppressants (Imuran, 6MP, Azathioprine):
-While the side effects compared to prednisone might not be as outwardly obvious - these are still very serious possible complications including cancer and liver damage. Imuran gave me serious liver problems and I was very ill. This is uncommon but worth noting.
The biologics can be no walk in the park either. You need to put a lot of thought into these drugs and get well monitored.
