Can Dysport Be Used After a Botox Treatment?

Sometimes, Botox lasts only a couple of months but usually most patients get 3-4 months out of it.  If it is wearing off then it is ok to switch to Dysport.

These products are very similar in their mechanism of action and side effects. They can both normally be used in the same patient without any issues. Usually waiting the normal 3-4 months between treatments should be sufficient. Your injector can determine how much of the product you will need based on your muscle movement.

It is perfectly safe to use Dysport if a former Botox user after the effects have worn off. ysport, Xeomin and Botox are all preparations of botulinum toxin A derived protein that works at the nerve-muscle interface to relax targeted muscles. Each preparation is slightly different, for example the protein size differs. Dysport and Xeomin have been around in Europe for a long time and more recently introduced in the USA. Note the dosage is not the same between the drugs though each works well in my experience.

It is fine to use Dysport after having Botox done.  I would however, wait until you have muscle movement return, typically in 3-4 months. 

While it's certainly safe to have Dysport injections after Botox, the one caution we would have is that we normally advise our patients to wait approximately 3-4 months between treatments. 

Although negative reactions to Botox are rare, we have seen in our practice (and this is supported by research) that when it occurs, a resistance to Botox (Dysport) can often present when the patient is using Botox more often than recommended.  This would be the only caution we have for your situation.

Chemically and clincically, these two items are very similar. As long as you have given the Botox enough time to show its clinical effect, which you have, you can now add the Dysport.  This is not too soon to add more Botox either, should it be needed.

Hi Auralay,
It is perfectly fine to have Dysport treatment 2 months after your previous Botox injections. In fact, it is safe to combine the products at the same time if indicated. Some patients prefer the effect of Dysport on crow's feet while they like what Botox does in other areas.
Good luck and be well.

Since Botox and Dysport are nealy identical (the active part of the molecule is the same) there shouldn't be any safety issues about combining them. Since you Botox was only 2 months ago, it should still be in effect so I presume you are considering treatment for another area. If that is the case, no worries.

I would recommend waithing approximately 4 to 5 months. There is no study that actually gives us the answer, but I think that time period is reasonable.

Dysport and Botox are very similar botulinum toxins and they can be used interchangeably without any problems. They both typically last about 4 months, although with repeated treatments, they do tend to last longer. Dysport tends to start working a few days faster than Botox.  Both are incredibly safe (when injected by highly trained physicians such as dermatologists) and well tested over many years. ~ Dr. Benjamin Barankin, Toronto Dermatology Centre.
