I have had regular Botox injections for the past 18 months. I recently read about Dysport and would like to begin using it. How long should I wait after my last Botox injection before starting Dysport?
Botox and Dyport are nearly the same products. They differ only in the companies that manufacture them and in the inactive surface proteins that encapsulate the active molecule. Immediately upon injection the outer proteins are separated from the active molecule releasing it to bind the the nerve end-plates causing the clinical muscle relaxation. In my opinion, the onset and duration of Botox and Dysport are exactly the same. So, to answer your question, you can begin using Dysport as soon as your Botox begins to decrease in activity.
