Summary
Baclofen and botulinum toxin both reduce muscle tone, so together they may cause excessive weakness, particularly if toxin spreads beyond the injection site.
What this interaction means in plain words
Baclofen and Letibotulinumtoxina 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
Pharmacodynamic synergism: central reduction of motor neuron excitability (baclofen) plus peripheral blockade of acetylcholine release at the neuromuscular junction (botulinum toxin).
What to do
Use the lowest effective toxin dose and watch for generalized weakness, swallowing difficulty or breathing problems after injection. Consider reducing the baclofen dose if weakness is excessive.
