Botox allergy - who is at risk?

Hi @little.mermaid.xo! This is an excellent question. Having a Botox allergy is rare. I would recommend doing a patch test to see if you react. Since you've had Botox in the past without any complications, you should be fine. Best of luck to you!

Hi there! An allergy to Botox has been reported but is very uncommon. There is discussion that those with severe egg or cow milk allergies should avoid Botox and Dysport. If you've had sensitivity to certain chemicals in the past, it is possible that you could react to Botox. The reaction tends to be localized, but it's not to say it can't be systemic. If you've had Botox in the past, it's likely you'll do fine. Your injector may suggest a small, test injection at one site to observe for any reaction. Hope this helps you!

Allergy to Botox is exceedingly rare. There have been only a few reported cases in the history of Botox. If you are truly concerned about this potential risk, please see an Allergist who can perform adequate testing regarding your potential allergy.

Allergic reactions to Botox are very rare, but there is no way to predict if you will have one or not. If you have serious concerns you can look into having an allergy test done prior to your treatment. Your prior reaction to fillers is not an indication of how you'll react to Botox.

The real answer is that the likelihood of an actual allergic reaction to a cosmetic botulinum toxin injection is extraordinarily low. This would be an immediate reaction where you develop hives or anaphylactic type response. It has been reported but practically it is so very rare that it is not a real clinical concern. A still rare but more common reaction are mild systemic side effects from a cosmetic botulinum toxin treatment. This include things like headache, flu like symptoms, or even awareness of swallowing, or less commonly actual difficulty swallowing. This occur perhaps one in 10,000 patients are not generally serious in the doses given for cosmetic treatment. Since they are actual systemic effects from the botulinum toxin used for treatment, they generally take days to develop and are maximal in about 10 days and often disappear shortly thereafter. A rare patient can have longer effects and be disturbed by then. For those unusually sensitive individuals, I will recommend avoiding botulinum toxin treatment altogether but let me stress how uncommon such reactions are. The reaction to a filler does not mean you are predisposed to a reaction to botulinum toxin.
