Summary
Botulinum toxin causes localized muscle weakness, and a centrally acting muscle relaxant may add to weakness in theory. The clinical significance at standard doses is probably small, but it is more relevant with large doses or distant spread of toxin.
What this interaction means in plain words
Letibotulinumtoxina and Methocarbamol 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
Theoretical additive muscle weakness from peripheral neuromuscular blockade by the toxin and central muscle relaxation by methocarbamol.
What to do
Monitor for generalized weakness, swallowing or breathing difficulty after injection. Seek urgent care if these occur.
