Summary
Corticosteroids given with neuromuscular blockers, particularly during prolonged ICU use, have been associated with acute quadriplegic myopathy. Fludrocortisone has predominantly mineralocorticoid activity, so the risk is likely lower than with glucocorticoids, and it may also cause hypokalemia that can alter blockade.
What this interaction means in plain words
Fludrocortisone and Pancuronium have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Fludrocortisone belongs to Endocrine; Pancuronium belongs to Musculoskeletal.
Why it happens
Proposed additive muscle toxicity (steroid myopathy with prolonged denervation-like effect of blockade), plus potassium shifts altering neuromuscular transmission.
What to do
Monitor serum potassium and muscle strength if prolonged blockade is needed. Use the lowest effective duration of pancuronium.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
