How safe is it to have long-term maintenance injections of Dysport?

Question

Every 3 months, I receive Dysport injections for crow’s feet, bunny lines, neck bands, brow wrinkles, and in the chin area. Could these injections eventually build up in my system and cause me health issues? Could the injections near my eyes cause dry eyes? If yes, how does Dysport cause dry eyes?

Barbara L. Persons, MD, FACS · Answer

I personally don't think that regular use of Dysport causes any health issues, and the research bears this out. In fact, often regular patients find they need their injections somewhat less frequently. Whatever works best for a particular patient is what I aim for. As far as the "dry eyes" question. From a technical, anatomical perspective, the orbicularis muscle is complex, and one portion of it does in fact contribute to lacrimation (tear formation.) However, if done properly, this is not a problem.What you are doing is safe, and I hope I have allayed your concerns.

There is no cumulative affect of neurotoxins.  the only thing could happen is that you become resistant to neurotoixn. This happen to very few patients. This means that the neurotoxins may not work for you. So there is no worry at all. We have been injecting patients since 1970's for medical purposes with no issues. I personally have been injecting some patients since 1999 every three to 4 months with no issue or problem.

Long term injections with neurotoxins are safe, even at high doses. They do not "build up" in your system as they go directly into nerve cells and stay there immediately after injection.  You have nothing to worry about!  Keep getting those injections.  Best, Dr. Emer.

Dysport is a very safe neuromodulator that has been FDA-approved and used for many years. There is no research to indicate that Dysport would cause any damage from being used long-term.

Michael H. Gold, MD · Answer

We have been injecting toxins for many years now, and routinely some of our patients have had 2-4 injections per year for upwards of 20 years. No problems are known with long-term use, and many report that patients who use toxins for a long time will stop having "those" wrinkles.
