Summary
Corticosteroids given with neuromuscular blocking agents have been associated with acute myopathy, mainly with prolonged use in critically ill patients. Corticosteroids may also alter the response to neuromuscular blockade, though this is mainly described with non-depolarizing agents. A single dose of succinylcholine is less likely to cause this problem than prolonged blocker infusion.
What this interaction means in plain words
Succinylcholine and Triamcinolone acetonide injectable have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Combined effects on muscle membrane function and protein catabolism may predispose to myopathy; the mechanism is not fully established.
What to do
Be aware of the risk of myopathy when prolonged neuromuscular blockade is combined with systemic steroids, and use the shortest effective duration. Monitor for unexplained weakness or difficulty weaning from ventilation.
