Food allergies in dogs occur when their immune system overreacts to certain proteins in their diet, mistakenly identifying them as harmful invaders.

Common symptoms of food allergies in dogs include itchy skin, ear infections, gastrointestinal issues like vomiting or diarrhea, and chronic skin conditions like hot spots or paw chewing.

Apoquel (Oclacitinib) is a medication specifically designed to treat allergic skin conditions and severe itching (pruritus) in dogs.

This blog post will explain the mechanism of action behind how Apoquel alleviates the symptoms of food allergies by reducing inflammation and controlling the itch-scratch cycle.


What is Apoquel (Oclacitinib)?

Apoquel (Oclacitinib) is a novel medication belonging to the class of drugs called Janus kinase (JAK) inhibitors. It was specifically developed for use in veterinary medicine to treat allergic skin conditions and chronic itching in dogs.

How does Apoquel work?

Apoquel works by inhibiting the JAK enzyme, which plays a crucial role in the inflammatory response and development of allergic symptoms like itching and skin irritation.

By blocking the JAK enzyme, Apoquel disrupts the inflammatory cascade and reduces the release of inflammatory proteins that contribute to the symptoms of food allergies in dogs.

This inhibition of the JAK pathway ultimately leads to a reduction in inflammation, skin irritation, and itching associated with food allergies.


The Role of Apoquel in Treating Food Allergies in Dogs

Food allergies in dogs can manifest with a range of uncomfortable symptoms, including chronic skin irritation, rashes, hot spots, and excessive itching or scratching.

These allergic reactions occur when a dog’s immune system mistakenly identifies certain food proteins as harmful invaders and mounts an inflammatory response.

The resulting inflammation can lead to skin issues and an unbearable itch that causes dogs to scratch incessantly, potentially leading to further skin damage and infections.

Apoquel helps alleviate these symptoms by reducing inflammation and breaking the itch-scratch cycle associated with food allergies. By inhibiting the JAK enzyme responsible for triggering inflammatory pathways, Apoquel effectively reduces skin redness, rashes, and inflamed lesions caused by allergic reactions.

Additionally, its anti-pruritic (anti-itch) effects provide relief from the relentless itching that plagues dogs with food allergies, preventing them from causing further trauma to their skin through excessive scratching or chewing.

Administering Apoquel to Dogs


Apoquel is available in tablet form and is administered orally to dogs once or twice daily, depending on the severity of their condition and the veterinarian’s recommendation. The typical dosage range is 0.18 to 0.27 mg per pound (0.4 to 0.6 mg/kg) of body weight.

Common Side Effects

While Apoquel is generally well-tolerated, some potential side effects may include;

  • vomiting
  • diarrhea
  • anorexia (lack of appetite)
  • lethargy

Pet owners should monitor their dogs closely for any adverse reactions and report them to their veterinarian immediately.

Apoquel should not be used in dogs with serious infections, as it may interfere with the immune system’s ability to fight off the infection effectively.

Complementary Treatments and Management

While Apoquel can provide significant relief from the symptoms of food allergies, identifying and eliminating the specific food allergens from the dog’s diet is crucial for long-term management.

This typically involves an elimination diet trial under veterinary guidance, where potential allergens are removed from the diet one by one until the offending proteins are identified.

In addition to dietary management, other complementary treatments may be recommended alongside Apoquel to provide comprehensive support.

Regular bathing with medicated shampoos can help soothe irritated skin and reduce bacterial or yeast overgrowth.

Topical ointments containing corticosteroids or antihistamines may also be prescribed to alleviate localized inflammation and itching.


Conclusion or Summary Paragraph:

Apoquel has proven to be an effective treatment option for managing the uncomfortable symptoms associated with food allergies in dogs.

By inhibiting the JAK enzyme and disrupting the inflammatory cascade, this medication provides relief from skin irritation, rashes, and relentless itching caused by allergic reactions to certain food proteins.

However, it’s important to note that while Apoquel can alleviate the symptoms, identifying and eliminating the specific dietary allergens is crucial for long-term management of food allergies in dogs.

Consulting with a veterinarian is essential for proper diagnosis and developing a comprehensive treatment plan. Veterinarians can guide pet owners through elimination diet trials, recommend complementary treatments like medicated baths or topical ointments, and monitor the dog’s response to Apoquel.

Pet owners should closely observe their dogs while on Apoquel and report any adverse effects or lack of improvement to their veterinarian promptly.


Is Apoquel safe for long-term use in dogs with food allergies?

Apoquel is generally considered safe for long-term use in dogs with food allergies, as long as it is administered under veterinary supervision and the dog’s condition is regularly monitored. However, like any medication, it should be used judiciously and with caution.

Can Apoquel be used in conjunction with other medications or supplements?

Yes, Apoquel can often be used in conjunction with other medications or supplements, but it’s important to consult with a veterinarian to ensure there are no potential interactions or contraindications.

How quickly can pet owners expect to see results after starting Apoquel?

Many pet owners report seeing noticeable improvement in their dog’s itching and skin inflammation within 1-2 weeks of starting Apoquel. However, individual responses may vary, and it may take longer for some dogs to experience full relief.

Are there any dietary restrictions or precautions when using Apoquel?

There are no specific dietary restrictions associated with Apoquel, but it’s important to follow the veterinarian’s recommendations regarding identifying and eliminating food allergens from the dog’s diet.

Can Apoquel be used to treat other types of allergies in dogs, such as environmental or flea allergies?

Yes, Apoquel can be effective in treating various types of allergies in dogs, including environmental allergies (atopic dermatitis) and flea allergies. Its anti-inflammatory and anti-pruritic properties can provide relief from the symptoms associated with these allergic conditions as well.
