Dysport for Patient Immune to Botox?

We believe there is a low probability that Dysport will work for you if Botox did not.  With that said, if Botox results are something that you still are very interested in attaining, then it's probably worth the risk of trying Dysport and failing.  

We would suggest going in and having a small area injected (maybe the area between the eyes) to see what the effect is.  While it's possible that you have developed a resistance to Botox in some manner, it's also possible that you were not injected correctly or that too little product was used previously.  Give it another shot and good luck!

I have answered this question before and will now repeat my explanation.

Dysport and Botox are both Botulinum Toxin type A products. They are, however, subtly different. It is this small difference that may account for Dysport working where Botox does not. In my practice I have treated a couple of patients that don't respond to Botox injections. They seem to be doing well with Dysport so far. Traditionally we have used Myoblock for these patients, but Dysport presents another options. I would recommend trying Dysport if you find that Botox is not effective.

I hope this info helps!

Chances of your getting a positive outcome from Dysport if Botox has not worked is very slight. The products are almost identical and both work the same way on the proteins that allow signals from nerve to muscle.
Most people end up with frown lines from unconsciously contracting the forehead muscles. One "old" way of combating that habit is to use a paper pasted over the wrinkled area (called Frownies). If you are consistent in using them, you can see some lessening of the frown lines.
If you do use them, pay attention to your skin and be sure to clean the area well after removing. If you have any skin irritation, stop using them.

Some people respond better to certain neurotoxins than others. If Botox didn't work for you, I would try Dysport or Xeomin. Jeuveau is also an option. It is rare to be immune to all of them.

Dysport is Botulinum B which is slightly different from Botox which is Botulinum A.  Therefore, although Botox may not work for you, Dysport very well may.

While it is quite possible that Dysport will not work for you if Botox didn't work for you, it also doesn't hurt to try it.  If you are interested in this type of treatment, you can try treating a single area to see if you respond or not.

Dysport is a close relative of Botox that is now available in the United States through Medicis. We have seen great results in patients who have previously used Botox or in patients new to these muscle relaxers. If you have use Botox but have not been satisfied with the results, you may consider using Dysport and you may consider a stronger concentration of Dysport as you may have stronger muscles in this area. The amount of Dysport used is slightly different than the amount of Botox per area. For great results, work with a board-certified plastic surgeon who has a great deal of experience with fillers, Botox and the new Dysport. The price of Dysport will vary by the practice. In our practice, Dysport is somewhat cheaper than Botox. Keep in mind when buying either filler to make sure that you are paying by the unit instead of by the volume (per area, per cc, per ml, etc)
 

I have had only a few patients over the years who did not respond at all to botox.  It is rare but does happen.  I think it is unlikely that you will respond to dysport because basically they are both botulinum toxin type A.

My guess is that it wont make a difference which you use... It may make a difference if you were seeing some results but they werent lasting? If you saw no results at all it is likely you wont with Dysport since they are the same botulinum toxin A working at the same areas. But since it is cheaper than Botox why not try it once at least?

Theoretically, it's possible that you may have been exposed to botulism at some point in your life, in which case you would have developed antibodies to the botulinum toxin. Typical symptoms of botulism involve nerve function, double vision, weakness, paralysis, etc, but maybe you had a mild case that resolved on its own.
Botulism is found in improperly canned foods as well as some other foods that have been improperly stored or handles.
Dysport is the same substance as BOTOX. They are both botulinim toxin type A, so i doubt that Dysport would work if BOTOX did not. There is a type B botulinum toxin called Myobloc which may work for you. It is FDA approved in the US for treatment of neck muscle spasm but not something that I use in my practice for cosmetic use.
