Oh, my mom also took Stelara in the beginning, when she hadn't had surgery. Actually she changed the biological, like, 3 or 4 times due to the surgeries (I think they stopped working after each surgery, something like that). They're all related, aren't they? All their names end in "mab" (Ustekinumab, Vedolizumab, etc etc).
All the best to you and your brother too! 🤗
