Summary
Both agents impair neuromuscular transmission, so combining them may increase muscle weakness. Distant spread of toxin effect could add to residual blockade and affect swallowing or breathing.
What this interaction means in plain words
Letibotulinumtoxina 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.
Why it happens
Additive impairment of neuromuscular transmission, presynaptic inhibition of acetylcholine release by the toxin plus postsynaptic nicotinic receptor blockade by rocuronium.
What to do
Monitor neuromuscular function and respiratory status closely and titrate rocuronium with a nerve stimulator in patients recently given botulinum toxin. Anticipate prolonged recovery after surgery.
