Am I being over prescribed medication?

I have been diagnosed with birdshot choryoretinopathy and have been prescribed Mycophenolate (500 mg) , one pill twice daily for 2 weeks, then two pills twice daily for another two weeks, until three pills twice daily.
Is that the usual prescription? It seems to be over prescribed. Why not keep to the one pill twice daily? I do not have many other symptoms- other than a retinal membrane and uveitis.

Durezol vs immunosuppressant therapy

Originally, I was diagnosed with APMPPE in 2017, and did not have uveitis, just the beginnings of an epiretinal membrane. Unfortunately, I developed uveitis within the past year, and my new Opthamologist has declared my condition to be Birdshot chorioretinopathy (as I now have tested positive for HLA-A29). I am on Durezol, and have been sent to a rheumatologist in order to receive Mycophenolate. Is this a normal procedure? Which medication works best for Birdshot/APMPPE (with fewer side effects)?
