Your hives might not be from the BTX-A
When you are injected with BOTOX® [or other formulations of BTX-A like Dysport® or XEOMIN®] you are also being exposed to other things, for example the benzyl alcohol which acts as both a preservative and a local anesthetic in the normal saline which most physicians use to reconstitute these medications.
It might be useful to ask your physician to skin test you to the normal saline which is being used to reconstitute your BTX-A. If you react to the normal saline, it is most likely to the benzyl alcohol.
A simple solution would be to ask your physician to reconstitute your BTX-A using normal saline without preservative [this can be purchased in 20 ml single-dose vials from Hospira, which is the same company that makes the more commonly used normal saline with preservative.]
It certainly sounds like you have developed an allergy to BOTOX.
Please recognize that hives or even anaphylactic reactions, although rare, are described for BOTOX and Dysport. You are now in this camp. Please do not have another treatment of BOTOX or any Botulinum toxin without consulting an allergist. This has noting to do with injection technique. This is a direct and potentially life threatening reaction to something in the product. This could be the botulinum toxin or the albumin in the product. If you have been getting the product for a medical reason, it is reasonable to get testing to determine precisely what you are allergic to and if what if anything should be done about it.
Hives and botox
Physicians need to be scientific in their approach and detectives in solving problems. Several questions need to be asked.
1. Are these truly hives? Hives move, they change within hours. Itchy red bumps that stay put are not hives.
2. Was it a protein in the Botox to which you reacted?
3. Was it a preservative in the Botox?
4. Was this Botox manufactured by Allergan, here in the U.S., or did your doctor purchase it from another source?
5. Are you reacting to a numbing cream applied prior to the injections?
If this is an allergic reaction there is a different type of rash than if it is an immune reaction of a different nature. Allergic reactions never do occur the first time someone is exposed to a chemical. You must first be sensitized to the chemical and the allergy can happen at any time in your life after you repeat the exposure. You may wish to see and allergist.and you might ask your doctor to supply you with a small amount of the Botox they have (by now it may be a different lot number since you were treated).

Hives after Botox?
Hi TW. We have seen this reaction in one other patient in the past. This particular patient was getting Botox often (many times at less than three month intervals) and developed the same type of reaction to the product you are speaking about.
While we are not sure how this allergy/resistance came about, she is no longer able to use Botox (or Dysport). You would be wise to stop having it injected given your reaction to it.

It certainly sounds like you are having an allergic reaction to something in the Botox formulation. My recommendation is to stop having any Botox injections and go see an allergist.
Hives or Allergy after Botox Cosmetic Injection
Allergic reactions or hives may occur from many different substances, including Botox Cosmetic. While rare, allergic reactions have been reported from Botox injections. It's possible to develop an allergy at any time. You should speak with your Botox specialist and be evaluated by an allergist. Only after a comprehensive evaluation can he/she help determine appropriate options for you. Best of luck.
Allergic to some preservative of Botox solution
The hives are an allergic reaction to something that's in the Botox solution and you should not have another Botox treatment before seeing an allergist and discussing the situation...possible testing etc. When allergic, the reaction to the allergen increases dramatically and can lead to airway constriction and serious medical issues.
Botox and allergies
Before you consider getting any more Botox injections, I would advise with an allergist if there is a component of the Botox that you have deleoped an allergy to. Most allergies occur after multple and prolonged exposure.
