We took Charlotte to the dermatologist this morning. She said that Charlotte has atopic dermatitis which has been causing the swelling in her eyelids and lower lip folds. The inhalant allergen/s (from the environment) caused the "classic" skin inflammation, which led to a mild yeast infection on her lips. Because she has been receiving Cytopoint injections, she has not felt itchy.
Before having her tested for allergies and then starting allergen immunotherapy, we are going to try this more benign treatment plan: Redonyl chews (an antihistamine), wiping her lip folds with an antimicrobial wipe, and applying an antifungal cream. We can add Benedryl if needed. We are going to follow up with a repeat visit in four weeks and if the antihistamines are working, wonderful! And if not, then we will proceed with allergy testing.
Something mysterious has been happening with Charlotte which the vet believes is an allergic reaction to an unknown source. On Monday morning, Wednesday morning, Thursday evening, and Friday and Saturday morning, she's developed swelling on parts of her eyelids. Sometimes there is a large area that is swollen, other times it looks like multiple hives. There is no discharge and her actual eyes are clear and normal. A few times she has had swelling on her lower lip -- but just on one side. None of this seems to itch or bother her.
We have given her Benedryl and have taken her to the vet three times for Dexamethasone injections. Each time, this has helped to bring down the swelling. She was also given a shot of an antibiotic on Wednesday and I have been giving her a probiotic. I have a prescription for six days of Prednisone (tapering) but have not given this to her yet since on some days she seems to be totally fine. We are returning to the vet on Tuesday to try to come up with a next step -- perhaps bloodwork and maybe a referral to a specialist or two.
We cannot identify anything that might be causing this and the occurrences seem random timewise. Her food is the same, the lawn hasn't been sprayed for pests, sometimes she is okay after a walk and sometimes she isn't. Sometimes she is fine when she wakes up in the morning and other times not. We haven't used any different cleaning products. We have been wiping her face and feet every time she comes inside, and she is never outside alone. We even shampooed her with a gentle shampoo to be sure that her coat is clean.
I am hoping that someone reading this will have an idea that we haven't considered. Thanks.
