This is urgent issue for many of us. I found Zydus' generic made my initial Dx of UC much worse. Total fail and I was on canasa & cortifiam and uceris. Went from mild/mid to mod/severe in 6 months.
Switched to Lialda, started immediate gradual improvement.
I ran out Jan 8, usually mail order for 3 months. fought for weeks to refill, manager @ optumrx and I called every store within 50 miles in NJ. I found 1 bottle. Took it and got the other 2, last week.
The generic has a different coating & doesn't dissolve in the colon correctly.
