Summary

What this interaction means in plain words
Olanzapine 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

What to do
No preventive action is usually needed; watch for generalized weakness, swallowing or breathing difficulty after injection. Use the lowest effective toxin dose.
