Is it safe to have botox if I have chronic urticaria not caused by botox? (Photos)

It is unusual to see an allergic reaction after Botox administration. Having performed thousands of injections, I have seen possibly 1 reaction.  While it is possible to develop an allergy to any antigen or protein, a true Botox allergy is rare.  Also based on your information, the last botox administration prior to the onset of urticaria was 5 months prior and therefore unlikely to be the causeThere are some options.  First is to put a small amount as a test spot to see if it elicits any reaction. THe other option is to try an alternative such as Dysport and Xeomin which have slightly different protein composition.  There is a topical wrinkle reducer on the horizon, but it may be several years before it becomes commercially available.  In addition, it would still be applied at the doctors office. All the bestDr Soni
