Thank you for your question megand8301. Resistance to Botox is rare. In many of these cases treatment with another neuromodulator such as Dysport or Xeomin will work. It is also important to know the dose used and make sure the dose that previously worked is used. I recommend speaking with your doctor for specific advice and checking with your previous doctor for the dosing previously used. Good luck!
First, I would like to know- did you have any movement whatsoever after your treatment(s)? Second, I would like to know, do you know how many units were used in each area. If you did not have any results whatsoever with both products (assuming they were re-constituted correctly and in appropriate doses) then you may not react to the active ingredient in both of these products, botulinum toxin A. Another option for you may be to try Xeomin, which has a different active ingredient called incobotulinumtoxinA. Xeomin works in the same way that Botox/Dysport do, by blocking nerve stimulation.
It is very rare to develop a botox resistance. Discuss this with your provider as sometimes a larger dose is needed. Also ensure you are going to a reputable board certified plastic surgeon/dermatologist.
Dosage, doctor are both important
It is rare for Botox, Dysport, or Xeomin "not to work". I have had patients report one works better/faster/longer than the others. Assuming you have a reputable, board certified dermatologist or plastic surgeon, the next step for you is to try Xeomin, or discuss a dosage change with your doctor.
Neither Botox nor Dysport working
Most cases of Botox "resistance" that I see in my clinic are usually due to underdosing. If, in fact, you have true Botox resistance, which is extremely rare, I would try Xeomin.
It would be helpful to know the units of Botox that was injected into the forehead. It may be that you need more units of Botox in that area. If it still doesn't work then you should try Xeomin. Best, Dr. Green
Poor Results with Botox and Dysport -- Try Xeomin
For patients that do not have optimal results with Botox or Dysport, I suggest trying Xeomin. It is also possible this is due to skill of injector. Please seek a board certified dermatologist. Best, Dr. Emer
Neither Botox nor Dysport are working for me. Could I be resistant? Or could it be technique? How can I tell?
Thank you for your question. The first step would be to identify the number of units you have recently received to see if your new doctor has given you the same dosing as you received previously to good effect. If this has remained constant and your new doctor gives injections in the same locations as your previous injectors you may have developed some tolerance to Botox and Dysport and you can try Xeomin as a possibility. If you have questions as to your surgeon's ability you can also seek a second opinion to see if they are able to have better results. Hope this helps.
Confused as to what you mean by zero effect
Botox - on label lasts for 3 months. When you state that you had one treatment every two years - that interval is extremely long. You state that at first you were completely frozen - how long were you completely frozen? If it was longer than 3 months, the botox worked as it should have. Rare to develop resistance, however I have had several patients where I changed from Botox -> Dysport -> Xiomen with great results. One way to know if it is technique, or perhaps old botox is to go to another practitioner where he./she can assure you the botox/disport is fresh and try it that way. Good luck.
May be more likely that you are using untreated muscles for creating expression you are concerned about. Additionally amount of medication used and user technique can both be factors. Doubt resistance is the issue as it is extremely rare .
