Summary
Drugs with anticholinergic activity may theoretically add to the neuromuscular weakness and systemic anticholinergic effects of botulinum toxin. Fluphenazine has modest anticholinergic properties, so the clinical effect is likely small. Spread of toxin effects such as dysphagia or generalized weakness would be the main concern.
What this interaction means in plain words
Fluphenazine and Prabotulinumtoxina 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 anticholinergic and neuromuscular effects at the neuromuscular junction.
What to do
Monitor for excessive weakness, swallowing or breathing difficulty after injection. No dose change is usually required.
