Signs of Botulism from Dysport

Given your reaction,  I would avoid any of the botulinum toxins. To the best of my knowledge, there is nothing that would make one toxin more likely to spread then the other. However, it is possible that you had an intravascular injection with systemic spread.

Although a systemic reaction to a typical cosmetic dose of Dysport is extremely unusual, I agree with the other opinions on this topic.  Generalized muscle weakness after a Botulinum toxin type A treatment would rule you out from future injections with Botox or Dysport.  I would also contact Medicis and the involved Doctor or clinic and confirm that you actually received Dysport and not something else.

In my practice you are NOT a candidate for any of the Botulinum toxin available on the market.

Reconsider

Are you wondering now if you should try Dysport again?  My answer would be NO.  I think you may have the same reaction again.  If you've done fine with Botox, you might consider trying that again.

While the molecules differ between Dysport and Botox, more is similar than different. You would not know which part caused this very unhealthy reaction. So I feel that there would be far too much risk for a totally elective procedure.
