Can Xeomin cause difficulty swallowing?

Xeomin is an FDA approved Botulinum toxin A that is very similar to BOTOX and Dysport. These are actually very safe products but mild to annoying side-effects are well described. Some are far more sensitive to these side-effects than others. In my experience, patients who develop distant side effects like you are describing for such a small dose are uncommon representing about one patient is several hundred. However, the side-effect you are describing are so unpleasant that generally it is advisable to avoid all botulinum toxin treatment in the future. It is simply not worth the unpleasant side-effects. Using a different botulinum toxin product will not prevent the side effect. This is not related to the injection technique. Rather this simply reflects your personal sensitivity to this agent.

Though very rare, difficulty swallowing after neuromodulator treatment can be from an allergic reaction. You may have a sensitivity to the product. Difficulty swallowing can sometimes occur if the neck area is injected.
