Summary
Anticholinergic drugs may add to the neuromuscular effects of botulinum toxin. This can increase muscle weakness or systemic anticholinergic effects, although the clinical significance with local injection is generally limited.
What this interaction means in plain words
Clemastine and Daxibotulinumtoxina can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
