Botox allergy - who is at risk?

Question

I am interested in getting Botox again once I am finished breastfeeding.. I have had delays reactions to fillers in the past (treated with Prednisone) and am allergic to hair dye. Would I be at risk for a botox allergy? I had it years ago but am worried to try it again given the lapse of time and the fact that I seem predisposed to chemical allergies.

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!

Hello and thank you for your question.Botox allergy is extremely rare. With your history an option would-be to have a patch test to see but it would be unlikely that you are allergic to botulinum toxin. Please always seek treatment from a trained medical professional for any cosmetic treatment. Best wishes

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.
