Hi , thanks for reaching out. Please know, that you are not alone. Unfortunately, certain medications can make one more susceptible to infections, which might explain the UTIs, although only your doctor can tell you for certain. I also wanted to share a discussion thread from another of our community members who asked about UTIs, https://inflammatoryboweldisease.net/forums/cystitis-with-ibd. You might find some of the comments there helpful as well.
How are you finding the Remicade to be as far as managing your Crohn's symptoms? Please know that this community is here for you!
