Summary
Anticholinergic drugs such as dimenhydrinate may add to the effects of botulinum toxin. This could in theory increase systemic anticholinergic symptoms or neuromuscular weakness, although the toxin is usually given locally.
What this interaction means in plain words
Dimenhydrinate 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
Additive anticholinergic effect on cholinergic transmission; the antihistamine acts at muscarinic receptors while the toxin blocks acetylcholine release.
What to do
Monitor for generalized weakness, swallowing or breathing difficulty and anticholinergic symptoms after injection. Consider avoiding unnecessary anticholinergics around the time of treatment.
