I have a 17 year-old female patient with a PMH spina bifida and a neurogenic bladder. Her pediatric urologist had referred her to me for evaluation of allergy to botox due to a complication with her bladder injections. At one point botox and lidocaine were used as the patient and her parents did not want to general anesthesia every three months for the injections. Most recently deflex material was used in the procedure as well. At no time was latex used.

It was noted within 24-48 hours that she had uncontrolled loss of urine via the stoma (her umbilicus). She was evaluated for a urinary infection and even treated with ciprofloxacin, but the cultures were negative and the loss of urine continued. Finally oral steroids were used and they did help. The patient has been getting these infections for 4 years and this has occurred with the two injections. I have tried to search for an allergy to this type of protocol including all mentioned medications used and any testing for such an adverse event, but have not found any literature to support testing in this circumstance. There are no rashes or any symptoms of anaphylaxis. I turn to your expert opinion on how to best manage this reaction.


The urologist concern seems to be if botox or lidocaine "allergy" could have caused loss of using via her stoma. In the absence of classic allergy symptoms, IgE mediated allergy seems an unlikely cause of "stoma failure".

As you are aware there are protocols to evaluate lidocaine reaction and one could consider these to satisfy the Urologists that lidocaine is not an issue.

In looking at Botox: I did fine a case report of a DTH type reaction to Botox used cosmetically but the patient did have pruritus and edema ( There was a previous "Ask the Expert" question that addressed Botox as well that might be helpful.

Delayed onset of urticaria and angioedema after botox and juvaderm
Q: 8/1/2017
A female in her late 30s with Hashimoto's presents with complaint of recurrent angioedema for a three month period in 2015, ten days after use of Botox and Juvaderm. She has not had hives or angioedema in the two years since then. She is concerned about the etiology and if related to meds.

Her first episode occurred in 2015 and involved eye swelling first, then progressed to bottom of her face feeling numb and swollen, the same day that she had had a massage.

The second episode occurred 1.5 weeks later. That morning she had noticed a two inch hive on her right arm. She had gone to the gym and then felt her left hand and left foot swelling and some light headedness like she was going to pass out. She was panicking. Hospital performed CT chest with IV contrast performed due to positive D Dimers and troponin 0.3 and results showed some calcified granulomas only. She was treated with parenteral steroids.

Pt is worried about having a life threatening disease. No family history of hives or AE.
Labs: 9-2015 Abnormals: Thyroid peroxidase ab 290, antithryroglobulin ab 1.2, high tot IgE 109, alk phos 149, Bilirubin 1.3, ALT 52.  IgM lyme screen +; 2 IgG bands positive (Rx Amoxicillin).

NORMALS: Urinalysis, TSH, H pylori, Complements c3, c4, and C1 inhibitor functional and quantitative, ESR, ANA.

In 2017, Pt returns due to concern that she could have had the angioedema in 2015 from either Botox that she used 10 days prior to incident or Juvaderm. She had both only once in a couple weeks prior to the onset of the angioedema episodes; previous to that she had had Botox before this at least 15 times, but none since. She also had taken an OTC med for UTI prior to the angioedema. She is dermatographic in general. She gets 'blotchy' if she has a glass of wine or gets upset. She had a baby 3 months prior on 5/15. She has hypothyroidism and her dose of Levoxyl was increased 6 months prior to episodes.  

For a three month period (which started 10 days after the meds) in 2015, apparently she had episodes of lip or eye angioedema requiring hospital visits at least 8 times due to swelling of lips or eyes, despite Zyrtec and Benadryl qhs. Some of these episodes were treated with steroids. She did not have any life threatening reactions involving her throat or lungs.  She is in fear of the cause and despite no intention of getting Botox or Juvaderm again, would like to know if that was the cause or some other unknown etiology as she is worried about something life threatening occurring unpredictably. The 2015 episodes and ER visits have made her anxious about the cause.

She is doing research online and contacted Mayo regarding Botox testing. She tolerated Lidocaine and has done so since the incident. Pt does not know diluent used in diluting Botox injections at the time. She is requesting testing.

Due to the delayed onset of symptoms, it is not descriptive of an hypersensitivity reaction to either medication. I could not find a report of botox testing online; can you detail the concentration at which one would prick and performed intradermal to Botox and Januvia to satisfy the patient’s request?

Would it be accurate to reassure her that if both tests are negative that she would not have an anaphylactic reaction to either in the future? I suspect the angioedema could be related to her underlying Hahimoto's but do not know why it was limited to those three months.
A: A delayed reaction occurring 10 days later would not be characteristic of an IgE-mediated reaction. Therefore, allergy skin testing would not be predictive of risk for a delayed reaction as in the case of your patient nor would negative tests be reassuring, as they have not been rigorously studied as in the case of penicillin skin testing, for example.

Of note, there is a case report in the literature (Rosenfield LK et al. Aesthetic Surgery Journal 2014:34(5):766-768) of a patient who developed ocular swelling the morning after the first Botox treatment, local pruritus after the second and third Botox treatments and pruritus of hands and feet 36 hours after receiving Botox and Juvederm. Prick skin tests were performed in serial dilutions (1:1000, 1:100, 1:10 and undiluted) followed by administration of a therapeutic intradermal dose. The skin tests and intradermal dose were negative. Patch testing was performed and it was positive, which suggested a T-cell mediated reaction. Reactions with this mechanism could manifest as allergic contact dermatitis, maculopapular exanthem, DRESS, SJS/TEN/EM, acute generalized exanthematous pustulosis or fixed drug eruption.

While from the description of the case an IgE mediated mechanism seems unlikely, I wonder if this could be a DTH type reaction that responded to steroids. It may be worthwhile to consider skin test and / patch testing to lidocaine and botox to see if this is insightful.

I hope this has been helpful.
