If I'm Allergic to Juvederm, What Should I Do?

True Allergies to Juvederm and other so called NASHA gel products (Non-Animal Stabilized Hyaluronic Acid) are exceedingly rare and the reason why no pre-testing for allergies needs to be undertaken when using these products like had to be done with older animal based products such as Zyderm/Zyplast.  Juvederm should not be used in patients with known allergies to Gram + bacterial proteins and the XC (the kind with numbing) variant should not be used additionally in someone allergic to lidocaine.  

That being said, it is very important that you follow up with a Dermatologist immediately to asses the situation and determine whether it is a true allergy or an infection and then begin the treatment algorithm depending upon the diagnosis.  If it is a true allergy the Juvederm should be dissolved with Hyaluronidase which should alleviate the problem, if it is infected you will require oral antibiotics.  In either case the Dermatologist may proceed with both treatments (Hyaluronidase and Antibiotics) as a cautious approach.  

The event needs to be reported to Allergan as an adverse event both for outcome reporting and more importantly to assist you with regards to whatever you may need for treatment.  They can be reached at 1-877-345-5372.  Feel better!

Allergies to Juvederm are rare.  People who have allergies to Gram positive bacterial proteins or to lidocaine (in the case of Juvederm XC) should not use Juvederm.

Whether this is an infection (I would be concerned that this is more likely) or an allergic reaction, you need to see a board certified dermatologist as soon as possible to have the filler dissolved and be properly treated for the reaction.

I will agree with the other response here that you need to report this reaction to Allergan.

This is from the Juvederm website:
