If I am allergic to Botox, can I have Dysport instead?

Question

I've had Botox twice in my life injected between my eyebrows and just above each eyebrow. 1st time I had it I had slight swelling/bruising that settled within a few days which I assumed was normal. The last time I developed huge swollen hard lumps at each injection site. My face swelled so much I looked unrecognisable. My injector said I had an allergic reaction. He prescribed me with prednisone, my face went back to normal within a week. Can I be tested to see if I would react badly to Dysport?

Thank you for your question. Allergic responses are not common. However when they do occur, we can switch brands. I would recommend that you get a little test spot on the back of the neck or in the forearm to see your response with Dysport.

True allergy to Botox is extremely rare.  Dysport and Xeomin also contains small amounts of additional proteins which at least in theory could be a source of allergic reaction.If you're convinced that you had a true allergic reaction to Botox I would be very careful using dysport.

It is more likely that you are allergic to the preservative in the saline that was used to mix the Botox. Also, maybe it wasn't Botox you received. Do a test with the saline with preservative on the forearm. You can do the same with Dysport if you are sure it was the Botox.
