Summary

What this interaction means in plain words
Rifampin and Upadacitinib can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Why it happens
Rifampin strongly induces CYP3A4, increasing upadacitinib clearance.
What to do
Avoid the combination, as labeling advises against strong CYP3A inducers. If rifampin is essential, monitor disease control and consider an alternative therapy.
