Summary

Rozanolixizumab blocks the neonatal Fc receptor and increases IgG clearance, which may lower infliximab concentrations. This could reduce infliximab efficacy.

What this interaction means in plain words

Infliximab and Rozanolixizumab can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Infliximab belongs to Musculoskeletal; Rozanolixizumab belongs to Miscellaneous.

Evidence level: Low

Why it happens

FcRn blockade reduces IgG recycling and shortens infliximab half-life.

What to do

Monitor for loss of infliximab response and consider trough level measurement. If infliximab is essential long term, consider an alternative to rozanolixizumab.
