Apoquel shortage? Try RESPIT!

By Jon Plant, DVM, DACVD

Bad news, good news about Apoquel® from Zoetis (NYSE: ZTS). We learned last week that the Apoquel backorder situation is likely to continue throughout 2014 and into the summer of 2015. That is very sad news for many itchy dogs and their owners.   On the positive side, those of us who started a lot of dogs on Apoquel when it was first released will seemingly have our current patients’ Apoquel requirements met, with regular allotments available for auto-shipping.

Despite the shortcomings in the supply, I am still a big fan of Apoquel based on my experience treating about 100 dogs. I have seen the pruritus (itch) score drop from a mean of 6.0/10 when beginning therapy to 2.5 after 4 weeks (the first point at which the score was recorded). In most cases, owners report that the pruritus improves within a few days, in accordance with the reports and publications from Zoetis. Meanwhile, I see very few adverse reactions. It is truly amazing and my clients are, on the whole, very grateful.

The Apoquel shortagshutterstock_105010115e leaves veterinarians with the traditional methods of controlling atopic dermatitis (“allergies”). The first step is to make the correct diagnosis by using a validated checklist and ruling out alternative diagnoses (see my short video on diagnosing atopic dermatitis). Once the diagnosis is made, the proven alternatives to Apoquel for effective therapy are:

  • Glucocorticoids – usually effective, but frequently cause undesirable short and long-term side effects.
  • Atopica® — often effective, but may cause vomiting and other gastrointestinal side effects.
  • Allergen testing/immunotherapy – both serum IgE testing and intradermal testing have reliability issues. See my recently published study that demonstrates that there is poor agreement between four serum IgE assays when you take into consideration random agreement.1 What is the value to the pet owner if we can’t be confident that the results are much more accurate than guessing?

All of which led me to develop RESPIT®, regionally-specific immunotherapy, a patent-pending approach that allows veterinarians to effectively desensitize patients with allergen mixtures optimized for their geographic region rather than based on an allergen test of questionable accuracy. Consider the following:

  • Every allergen testing company and most veterinary dermatologists report similar levels of efficacy for their immunotherapy based on these discrepant test results.
  • A committee composed of experts on canine atopic dermatitis found that there was no evidence to recommend one form of testing over another.2
  • Another study found that immunotherapy with a standardized allergen mixture is as effective as immunotherapy based on intradermal test results.3

Why are we still using these tests??? Would we submit blood for CBC’s if every lab gave us different results and we didn’t know which, if any, was accurate? More and more veterinarians are recommending RESPIT, recognizing it as a practical and cost-effective approach when you consider the facts about allergy testing.

Veterinarians can order RESPIT at www.skinvetproducts.com. Pet owners can learn more at http://vetrespit.com/pet-parents.html and request that more information is sent to their veterinarian.

    What is the client cost for a month supply of oral RESPIT for a 60 lb dog? I tried immunotherapy years ago, but my needle phobic dog refused the shots. He is now on a daily dose of 50 mg Atopica, but it is not keeping him symptom free. Because he is not being treated by a dermatologist, he will not be able to get Apoquel for many months. (Which actually made me cry when I found out.)

    My English bulldog has suffered from food allergies as well as environmental ones and she has tried everything. We even cook her own food. After trying Apoquel I thought my little one was in paradise again. It works great but now I’m heartbroken is no longer available. I only have a few pills left and I wanted to know if she would be a good candidate for RESPIT? Will it work like Apoquel? Thank you.

      Ericka,
      This is not really an advice column for individual pets and you’ll need to check with your veterinarian on what they would recommend. RESPIT is a form of allergy immunotherapy, not a drug like Apoquel. They are very dissimilar in their mechanism of action and RESPIT will not take effect quickly like Apoquel does.
