I only needed the initial treatment with the 4 injections. However, the doctor mentioned that if the colitis returns I could take methotrexate orally.
The other autoimmune condition I had did not go away with Budesonide- better though. I decided that I wanted to try Imuran. It definitely suppresses your immune system- I ended up having several different infections, getting worried. I quit after 7 months. I had regular blood tests to monitor blood counts.
