Summary
Drugs with anticholinergic or neuromuscular effects may potentiate botulinum toxin and lead to excess weakness. Haloperidol has only weak anticholinergic activity, so a clinically meaningful interaction is unlikely and poorly documented.
What this interaction means in plain words
Haloperidol and Letibotulinumtoxina 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
Possible additive pharmacodynamic effect on neuromuscular or anticholinergic function; not well established for haloperidol.
What to do
No routine change is needed; watch for unusual generalized muscle weakness, swallowing or breathing difficulty after injection.
