Is Xeomin the least likely neuromodulator to cause a reaction?

As you indicate it was a panic attack rather than mast cell degranulation syndrome leading to anayphylaxis. However, I have an expanded notion of what people experience as clinical botulism.  I have seen individuals experience a generalized panic reaction to larger (and sometimes smaller) doses of Botox.  Xeomin is not an alternative to this.  I suspect if you have a large enough dose of Xeomin or Dysport, you could experience a similar reaction.  You may nor may not experience this with the smaller cosmetic dose.  If you do, I would recommend avoiding any cosmetic botulinum toxin treatments in the future.

Both Xeomin and Botox are purified proteins used to decrease muscular movement of the upper facial muscles..Botox has been used on the very young and old for a host of problems.  There mode of action is similar so patients can use either.

Hi and thank you for your question. As Xeomin is the softest, shortest lasting brand of wrinkle relaxer it can be less likely to cause an adverse reaction such as a ptosis as it is not completely stopping the treated muscle from contracting.

Wishing you all the best,
