Can I Give the Super Snout Chill Out Tablets Again After 6 Hours
Part One: A New Wonder Drug for Itchy Dogs?
When you have a crazily itchy dog or cat, everybody suffers. Patients in this state often keep you upward at night and drive yous crazy during the day dealing with the mad itch.
Scratching, bitter, losing hair, skin red and inflamed, these guys oft stink, ooze mucilaginous wet from their pare, and many can't get comfy long enough to have a decent nap, permit alone sleep the night through.
Talk about a pain for you and your loved ones!
At the base of wildly itchy animals is the immune system, which is working overtime, but malfunctioning.
"Dysregulated" is a term used in the scientific papers.
(We accept to insert a wink here because immune organisation dysregulation is entirely a manmade disease. More on that later on.)
Interestingly, nigh look right past that important manmade indicate and seek to "ready" the itchy animal with powerful drugs.
Enter the latest anti-inflammatory drug to make a splash in the veterinary marketplace: Apoquel (oclacitinib).
And lest you think I'one thousand recommending it, you'll want to read on for the details about why an abundance of circumspection is recommended earlier yous plunk downwardly your hard-earned money and start your dog downward a potentially unsafe path.
Apoquel is non for puppies. Or cats or people. It'south Apoquel for dogs that we're talking virtually.
Born from the loins of the world'south largest drugmaker Pfizer, their former partition Zoetis is now the "animal health" giant that brought this much-touted wonder drug to market in 2014.
How big is Zoetis?
$4.34 billion in revenue in 2012, earlier Apoquel had even hit the market.
So: Big.
Stops Itch FAST!
The claims and even the actual results in itchy dogs are amazing.
Provides onset of relief within 4 hours. Finer controls itch within 24 hours."
Irresistible, right?
After you've lost sleep for weeks on end and tried everything offered you by Dr. WhiteCoat and Dr. Google without success, wouldn't this sound like heaven in a pill?
Apoquel sold similar hotcakes when it first appeared. Interestingly, there was quickly a shortage in supply, so the demand was heightened fifty-fifty farther, as desperate dog owners sought vets who had some.
"We'll buy whatever size y'all've got, we'll cutting the giant breed size to work for our Chihuahua, we just Demand TO GET THIS Itch UNDER Control!"
I might surmise that shortage was intentional, only that'due south beyond the scope of this article.
The company'due south research and the experience of many dog owners approve this: this wonder drug stops itching almost immediately.
Apoquel: How Does information technology Work?
Ah, now you're asking a smart question. I dearest it when y'all exercise this.
How Apoquel works is the cardinal to why you demand to exist smart.
Smarter than the marketers, smarter than Zoetis, and smarter than Dr. WhiteCoat, who'd exist tickled to sell this to yous.
(He, similar me in the old days of conventional medicine, hasn't likely read the research on safety or efficacy. He'due south merely taking his Zoetis rep'south give-and-take for information technology: it works! But judge who did the research… and for how long? A: Zoetis! thirty days!)
Pull up a little closer to the bivouac for this role, because here's where the story gets good.
Why is my Dog and so Damned Itchy??
To know how the drug works, yous should know first how The Itch works.
Hither's what a lath-certified veterinary dermatologist says causes The Itch:
- Flea allergy dermatitis
- Atopic dermatitis
- Food allergy dermatitis
- Contact dermatitis
- Sarcoptic mange
- Demodectic mange

I really, actually wish I was making this upward. (He'due south merely listed itchy diseases, cipher about their causes).
Just, while that explanation is seriously lacking in the "why?", the part he does get right is this:
That'southward been true for about fifteen years at present. Hard insurance data tell no lies.
Remember that wild and crazy immune system, spoken of earlier? The one that's off the rails, acting all whacky and dysregulated?
That's what Apoquel is interim on. It'due south being called an "immune modulator" by the experts.
That'due south an enticing way of calling out its action.
Sounds suspiciously benign.
Keep reading though, and you'll see that it's anything but.
In Office Two, I go into how that dermatologist actually missed the larger point of what causes itch. And how to work to truly prevent this maddening affliction from wreaking havoc on your own animals. As you might approximate, prevention in a real sense volition trump giving a drug to try to control this painful disease.
For now, here's a brief description of how this "wonder drug" called Apoquel works.
Immunology 101
First, an important understanding. While it might seem like we know a lot about the immune response, there are notwithstanding large swaths of mystery we don't nevertheless comprehend.
Past its very nature, this is 1 complex system! If we didn't have it, we'd accept been lost as a species a very long time ago, right along with our pets and our livestock.
That said, we know at that place are lots of messenger molecules involved.
And sweeping events called cascades, where the right trigger (a virus, say) causes a series of chemical letters and events that, when all is working well keeps you lot and your animals out of harm's fashion.
"Yo. We Need to Talk"
I group of immune messengers are called cytokines.
These small-scale molecules are produced past a broad variety of cells, and they signal other cells to do something like come up to the scene of infection, permit loose their chemicals, have function in signaling others, dump antibodies, etc.
You've likely heard of some cytokines before.
- Interferon
- Interleukins
- Tumor necrosis factors
When inflammation is triggered, these chemical messengers call in the troops. It's time to heal!
(More than on inflammation in context here. It'due south not the enemy, by the manner.)
Enter Apoquel (Oclacitinib)
A couple of words subconscious in those names. A whole class of inhibitory compounds human being has invented have "inib" at their finish. Short for inhibit.
And "quel?" You go that one.
Chill out this hot mess of inflammation!
So, this drug seeks to stop a slice of the inflammatory chemic cascade by interfering with sure enzymes chosen kinases, or JAK in the literature, which stops some cytokines from doing their affair.
And it works!
Simply similar all things that "work," nosotros need to await a bit deeper if we want to raise truly Vital Animals. "Piece of work" can hateful cure but it more often ways palliation:
Palliation means, while the medicine is being given, the symptoms are relatively controlled. The creature is no better overall and once the drug stops, the symptoms return. In the concurrently, the affliction is slowly growing and getting less probable to be able to exist cured.
Usually, there'due south a cost to pay in long term wellness when we interfere with Mother Nature, and this drug is no exception.
Apoquel and Long Term Rubber? Not And then Much.
My Texas colleague Dr. Ron Hines has done a bright job of cataloging feedback from animal owners really using this drug.
You, dear readers, have also contributed many, many of your ain experiences in the comments on this article.
When you read by the glowing reports of "Hallelujah! Peace at concluding!" you start to pick up a theme.
Those who've been using this drug for a while are seeing two common problems. Variations of these occur in most all drugs, in fact, not but this 1:
- Side effects
- No longer helping as much as information technology did at first.
Hither are a few existent people, real dog problems I highlighted. Y'all'll see more if yous dig further.
[8 months on the drug, Bishon]
The drug has given my dog (four years old) a quality of life I never idea was possible. He too receives an allergy serum injection every x days. However, for the past several weeks his nose has been running constantly and as of tardily he has been gurgling rather than breathing. Ii days agone, his nose was bleeding. I stopped the Apoquel immediately and volition see the allergist this week. Most importantly, two days after I stopped the Apoquel, his nose dried upwardly, no more running and no more claret. I cannot help but presume that the Apoquel was the crusade of his misery."
[6 mo. on the drug, Mini Dachshund]
She has gained virtually 3 pounds, and has become very yeasty and smelly. She besides has pain going downwardly stairs and playing. In reading nearly Xeljanz (a human variation of Apoquel) in an advertisement in a mag, I noted that this drug is an immunosuppressant. Yep it works for the itching, but I am concerned about the changes in her wellness since taking this drug."
[1 year on the drug, Mini Schnauzer]
Curly has just been discharged afterward four days in the hospital. He was hospitalized due to a mysterious 105ºF fever, lack of appetite, huge papilloma lesions in his mouth, vomit,and intestinal hurting… It worked only in the beginning, and now it barely provides some balmy relief to his crawling; he chews his paws raw and now his face up and legs and stomach itch a lot, too…
And so here is our challenge: It seems that Apoquel has greatly contributed to weaken Curly'southward immune arrangement to the point that his platelets and also his red claret prison cell count is considerably low. At the same time, he is experiencing very piddling relief by taking information technology. The internist believes that standing the Apoquel any further (would) wreak havoc in his immune system, that we can only await more papilloma lesions, farther inflammation of his lymph nodes, lower platelet cell cell count and so on."
As well of note, this drug is not labeled for cats. Or pups under 12 months quondam.
Hmmm. What are they telling us in between the lines here?
Tin Apoquel Cause Cancer in Dogs?
Before I share some real dog, real people experiences on that, permit's make sure y'all are aware of something.
Did you know that, for decades at present at least, immunologists have known that you lot and I and every animal on the cute blue planet are making "mistakes" in our cells every day?
They are called mutations.
Mutations happen during cell segmentation, which is pretty much a not-stop process in a living being. When you've worn out a liver prison cell or you've got to knit a cut dorsum to normal airtight skin, it's prison cell division that makes this possible.
Only, like all biological systems, cell partition isn't a perfect procedure.
Some "oopsies" happen, and the copy comes out incorrect.
Some mutations are harmless, some, when certain genes are involved, cause runaway cell division way by what'due south necessary.
The result? Tumors.
Tumor cells are in me and you and your domestic dog right now
The understanding of those steeped in immunology is that it'southward our immune organisation that is the sole reason every mutation that starts running wild in cell division doesn't create cancer.
The tertiary procedure is referred to as tumor immune surveillance, whereby the immune system identifies cancerous and/or precancerous cells and eliminates them earlier they can cause harm. The idea that the immune system, which so effectively protects the host from microbial pathogens, might too recognize and destroy tumor cells was first discussed over a century ago and has recently been reviewed in detail
source: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1857231/
We likely accept regular battles waged on cancer cells that never become tumors.
Why?
Our immune system correctly "saw" these cells every bit foreigners.
And chosen in the guard, like white blood cells, complement, interferon, natural killer cells, etc.
And like those kinases, known to be great communicators that assistance coordinate the attack on the wayward cells leaning towards condign cancerous.
What's Apoquel good at?
Taking out some of those kinases, remember?
Is an immune advice breakdown possible, when we mess with the kinases?
I'd bet on it.
And, it'due south as if Zoetis never got the memo about how important our allowed system is to prevent cancer:
APOQUEL may increase the chances of developing serious infections, and may cause existing parasitic skin infestations or ** pre-existing cancers** (emphasis mine) to get worse. — company literature
Pre-existing cancers?
Isn't that what we've known about for all these decades?
They are ALL pre-existing until they become a dark-green low-cal to grow, aren't they?
Allow the Apoquel Dogs Speak
Here'southward a handful of the many comments that say that'southward likely far better than I could:
Linda, young High german Shepherd
My iv year old gsd was on it for itching. She died 2 months later with lymphoma
Carley, 7 yr old Aussie Shepherd
Practise either of your dogs have hard lumps in their lymph nodes? Unfortunately my dog was diagnosed with lymphoma after using apoquel. I'thou in the procedure of collecting more data if there is a connectedness because my vet brought information technology to my attention (not the vet that prescribed the apoquel) my dog is a 7 year Australian shepherd lab mix and has been completely salubrious and happy minus his allergies. In comes the apoquel and then the lymphoma it's hard to non call back information technology is related
Dan, Bedlington Terrier
Our domestic dog (Bedlington) had horrible grass allergies. He would scratch himself encarmine. Nosotros put him on Apoquel because he could not sleep from all his scratching. It was a wonder drug and his itching stopped after 24 hours. His coat came back, and he was a new dog. 2 months later he had a benign cancerous skin lesion on his nose that had to be removed. Wish nosotros had continued the drug to that problem. four months after that he developed squamous cell carcinoma in his lower jaw and died three months later on.
Bruce M, Boxer
My sweet boxer Daisy turns 5 in 10 days. She has had allergies for well-nigh her entire life, and we have tried a diverseness of nutrition changes and treatments. She got a prednisone shot in May, and it lasted most 3 weeks. A clerk at the vets role said they could give u.s. "something" in a pill form, and it would last longer and has proven to exist very constructive. Information technology'due south a very adept vet practice, then nosotros trusted them completely.
On June 23, I began to give her the "pill". It was apoquel. Within a calendar week, the lymph nodes under her jaw began to not bad. Took her to the vet the side by side week, and the needle aspiration was inconclusive. It turns out her lymph nodes were bloated behind her legs as well. They did a biopsy, and nosotros were informed today that she has lymphoma. She too defecated pure claret today.
I asked the vet, "did apoquel expedite the cancer that was in her body"? He said "yep", because it compromised her immune system and allowed the cancer to take over.
Too Skilful to Be True? I'd Put Money On Information technology.
And so, a big circumspection hither, equally with all "miracle" drugs.
If information technology'south interfering with your dog'south immune system, and running out of gas after a certain period of use, is there any hope that it will cure your dog's itch?
Of class not.
Every bit you've learned, if you've followed along for any length of time, drugs never cure chronic disease.
They cannot.

In Function 2 of this series, we look at the real causes of The Itch, and allowed dysregulation.
Neither of these fell from the sky and happened to land on your poor innocent dog, as you likely have guessed.
