There are several articles and forums discussing the advantage of one versus the other. Many physicians are opting for Botox because it has been on the market for many years. Others are using it because of convenience. Some doctors will inject whichever is preferred by the patient.
No studies or reports have indicated that one provides a longer response than the other. Dysport has a wider range of diffusion which makes it attractive for certain indications, such as the eyes or neck. Xeomin has not been used extensively in this country. Some doctors have reported problems similar to those I experienced, related to the reconstitution of the powder prior to its use. We have since corrected the problem so that Xeomin is another option for our patients.
Our practice has experience with all the neuromodulators, their indications, and their safety profiles, so feel free to discuss any of your concerns with us when you come in for your consults.
