My Daughter, Aged 46 Has Proven Rheumatoid Arthritis. Methotrexate By

My daughter, aged 46 has proven Rheumatoid Arthritis. methotrexate by moth makes her ill all week: by injection she feels bad for about 2 days a week. her joints are mildly swollen and painful even on methotrexate and she suffers from frequent skin infections (Boils).
I understand that she has to go through a number of hoops before she is allowed Humera on the PBS. her rheumatologist refuses to even consider the change. What is the situation relating to Humera?
