When I started Entyvio I was in a flare that just would not quit. I was taking prednisone. After a couple of months the Entyvio started working and I have not taken steroids since.
I am lucky to have an excellent GI specialist who is an expert on IBD. It makes a huge difference. When I first met him he joked I have two diseases, UC and prednisone.
For anyone in BC it is Dr. Brian Bressler at the IBD Center of BC in Vancouver. I worship him. He just totally gets it.
Entyvio is fairly new as in maybe 8 years or so. In Canada it is paid for by our healthcare system, which is good as it is scary expensive. There are other "biologics" such as inflixamab and some have generic versions now.
I don't have stats but I know they are going to biologics earlier now. I had way too much prednisone over my life. It works but has bad side effects.
I have been on pretty much all the older treatments, including Asacol. Salofalk, azathioprine etc etc.
Colitis is no fun. It has ruined many things for me and I struggled with work at times. I am retired now but had a high demand profession and running to the bathroom was to say the least difficult.
I still have some joint pain as Entyvio mostly treats the gut but I can live with it.
I really hope your husband gets better quickly.
