VSL isn’t discontinued, but it’s very hard to find now. Sam’s Club still can get it for me, but that was the eighth pharmacy I called. You might have better luck finding Visbiom, which is the original formula VSL is based on. I see that they have an ad on the right side of this page, so they are supporting the J-pouch forum. It’s packaged just like VSL #3, including prescription and non-prescription strengths.
Long-term antibiotics are standard treatment for chronic pouchitis, but not every doctor (or even every gastroenterologist) knows that. I do get mine from a gastroenterologist. Perhaps you could print out the articles referenced at the top of this Pouchitis forum in the thread called “Need a Good Article About Pouchitis?” (https://www.j-pouch.org/topic/...icle-about-pouchitis) and give it/them to your doctor. Alternately you could look for a doctor who knows more about pouchitis.
A gastroenterologist would also be a good source for an appropriate biologic.
