How Do I Know if I Had an Allergic Reaction to Juvederm Injections?

Hi,
The best way of determining whether you are allergic to Juvederm (hyaluronic acid) would be to have a very small bleb injected into your forearm, and then watch for swelling, etc. I have seen two patients over the years with allergic response to hyaluronic acid, and both showed immediate swelling when their arms were tested.
It sounds and looks as if you also suffered from excessive bleeding and bruising. It is difficult to say exactly what happened without knowing how much was injected, what technique was used, and how much bleeding there was during the injections. What did your physician tell you? Was this the first time that you have had Juvederm? Are you sure that what you received was Juvederm?
You probably don't need anyone's advice on this, but I would advise staying away from hyaluronic acid injections in the future given your response. I hope that your swelling and adverse effects resolve quickly.
Be well.

Juvederm is a hyaluronic acid dermal filler that’s
associated with excellent clinical results and high satisfaction rates. Hyaluronic acid is a naturally occurring
material that’s formed in our bodies. For this reason, it’s very unusual to have true allergic reactions when
using Juvederm as a dermal filler. Allergic
reactions are often characterized by redness and swelling. In some cases systemic manifestations such as
airway swelling may occur as well.Your
pictures suggest that your swelling and bruising may be related to injection
technique. Under these circumstances,
it’s appropriate to perform skin testing to rule out a true allergic
reaction. If a true allergic reaction
has occurred, removal of the hyaluronic acid with hyaluronidase is appropriate. Systemic steroids may be indicated as well. If
you’re concerned about an allergic reaction, it’s important to discuss this
issue with your plastic surgeon. Your
surgeon should be able to make an appropriate recommendation.

Typically, allergic reactions to Juvederm is rare. The product is free of animal products and the body recognizes hyaluronic acid; therefore allergic reactions are not common. But if you suffered a reaction that has not resolved over the course of a few weeks, r is getting worse at any time, my advice is to see your physician as soon as possible and have them run a skin test. Also, not that local irritation or other side effects such as bruising from the injection and even infections may occur. A dermatologist should be able to discern the difference in etiology.
