For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.
Summary
Aminoglycosides such as neomycin can impair neuromuscular transmission and may potentiate botulinum toxin, causing excessive weakness. With topical neomycin, systemic absorption is low, so the risk is small.
What this interaction means in plain words
Dexamethasone-neomycin-polymyxin and Incobotulinumtoxina 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
Aminoglycosides reduce presynaptic acetylcholine release, adding to the neuromuscular blockade of botulinum toxin.
What to do
Monitor for excessive muscle weakness, swallowing or breathing difficulty. Avoid systemic aminoglycosides around botulinum toxin treatment when possible.
What to ask your pharmacist
