Itchy Rash After Botox

Hi Fallon.  Although it's possible that the Botox injection is related to the rash, it's highly unlikely.  Do you know how long after the injection you saw the rash and itchiness?

Your best bet is to return to your injector or a dermatologist fairly quickly to have the problem diagnosed.  

It is highly unusual to have an allergic skin eruption after botox, especially to last so long as yours. See a dermatologist to determine if there is any other cause for the rash which might have been coincidental with the Botox injections.

Botox contains small portions of human protein (albumin) as well as the botulinum toxin. There maybe other additives but these are negligible. However, surgeons use a variety of solutions to dilute the botox. Most use unpreserved saline but others used preserved saline. Allergies to the preservatives are possible as well as the topical anesthetic agents or skin preps used immediately prior to injection. Discuss this with your surgeon.
