Allergic Reaction to Botox...When Will the Symptoms Go Away???

Contrary to what panel members are suggesting, we have had personal experience with a staff member that developed an allergy to both Dysport and Botox that was not an immediate response but progressed to this because she was unaware of the link to the Botox injections.  

We have also met two other practitioners that have reported an allergy (not resistance only) to these products that do not involve flu-like symptoms such as nausea/vomiting.  In our staff member's case, she develops large, nodules at each injection site with surrounding hives and swelling.  

Although we believe that a true allergy to Botox is uncommon, it certainly should not be considered "rare".  We don't believe that there is enough interest form the manufacturers or scientific community to pursue studies to speak to this in depth.  Besides being under-reported, many may not recognize symptoms of a potential resistance or allergy to these products.

In summary, report your condition to Allergan (the manufacturer) as well as your practitioner.

It is very rare but there have been reports of allergic reactions to Botox. Please refrain from getting anymore treatments and follow the advice of your doctor.

Allergies to Botox are very rare and if they occur, a true allergy would be manifested immediately not three days later.  There are other type of drug reactions that can be delayed.  It might be a component in the Botox or a component in the liquid used to dilute the Botox. You should see an allergist to whom the doctor who did your Botox refers you so they can provide the allergist with a sample of the diluent (liquid used to dissolve the Botox) and the Botox after diluted. The allergist can then test you to both. However, they need to treat you now to make the  hives go away. it may be coincidental and related to a totally different issue believe it or not.
