Summary
Corticosteroids given with neuromuscular blockers, particularly in prolonged critical care use, are associated with acute myopathy. This can cause prolonged weakness and delayed ventilator weaning.
What this interaction means in plain words
Deflazacort and Rocuronium 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.
Deflazacort belongs to Miscellaneous; Rocuronium belongs to Musculoskeletal.
Why it happens
The mechanism is not fully established; steroid-related muscle catabolism combined with prolonged neuromuscular blockade is thought to contribute.
What to do
Limit the duration and dose of neuromuscular blockade and corticosteroid where possible. Monitor for persistent weakness and consider creatine kinase measurement if it occurs.
