🩹 What Are the Long-Term Side Effects of Apoquel? Immune Suppression and More
Apoquel works by suppressing part of your dog’s immune system to reduce the inflammatory response that leads to itching. While this is effective for controlling symptoms, the long-term use of immune-suppressing medications like Apoquel can lead to several side effects. Over time, dogs on Apoquel may become more susceptible to infections, skin issues, and other health conditions due to reduced immune function.
| Long-Term Side Effect | How It Affects Your Dog | 💡 Tip |
|---|---|---|
| Increased Risk of Infections | Reduced immune response may lead to more frequent infections, including skin, ear, or urinary tract infections. 🦠 | Monitor for signs of infections like itching, redness, or foul odors. 👃 |
| Possible Increased Cancer Risk | Some studies have suggested a potential link between long-term Apoquel use and an increased risk of certain cancers. 🧬 | Regular vet check-ups are crucial to monitor for abnormal growths. 🔬 |
| Changes in Bloodwork | Long-term use may lead to changes in your dog’s white blood cell count or liver values, indicating immune suppression or organ strain. 🧪 | Have routine blood tests done every 6 months. 🩸 |
| Gastrointestinal Upset | Long-term use can sometimes cause chronic diarrhea or vomiting. 🍽️ | Ensure your dog is eating well and staying hydrated. 💧 |
💡 Expert Insight: Not all dogs experience serious side effects, but long-term use requires regular monitoring. The key is finding the balance between managing your dog’s allergic symptoms and minimizing potential health risks.
🐕 Can Apoquel Cause Cancer in Dogs? What the Studies Say
One of the most concerning questions about long-term Apoquel use is its potential link to cancer. While Apoquel itself is not classified as a carcinogen, its mechanism of immune suppression could theoretically allow cancer cells to grow unchecked. Some studies and anecdotal reports have noted an increase in mast cell tumors, lymphoma, or other cancers in dogs on long-term Apoquel, though conclusive evidence is still lacking.
It’s important to note that Apoquel is not a direct cause of cancer. However, if your dog has a history of cancer or is at a higher genetic risk for developing tumors, long-term use of immune-suppressing medications may increase the likelihood of cancer progression.
💡 Pro Tip: If your dog has been on Apoquel for an extended period, ask your vet to regularly check for lumps, bumps, or unusual growths. Early detection is key in managing potential health issues.
🩺 How Do You Monitor Your Dog While on Apoquel? Regular Check-Ups and Blood Tests Are Essential
Given the potential long-term side effects, monitoring your dog’s health while on Apoquel is critical. Most vets recommend regular bloodwork and physical exams every 6 months to a year to ensure there are no hidden issues like changes in liver function, white blood cell count, or other indicators of immune suppression.
| Monitoring Method | Why It’s Important | 💡 Tip |
|---|---|---|
| Routine Blood Tests | Helps detect changes in white blood cells, liver enzymes, and overall health status. 🩸 | Schedule biannual tests to keep a close eye on organ function. 📅 |
| Regular Physical Exams | Allows your vet to check for lumps, infections, or any signs of cancer. 🐕🦺 | Combine these exams with regular grooming appointments to check for skin issues. ✂️ |
| Behavioral Monitoring | Changes in your dog’s energy levels, appetite, or behavior can signal underlying problems. 🐾 | Keep a log of any unusual symptoms or changes and report them to your vet. 📓 |
💡 Expert Insight: Being proactive with preventive care will help you catch potential side effects early and adjust the treatment plan if needed.

FAQs
Q: How long can a dog safely stay on Apoquel?
Apoquel is designed for both short-term and long-term use in dogs, but the safety of extended use depends heavily on individual health factors and consistent monitoring. Many dogs can safely take Apoquel for months or even years, as long as they’re regularly monitored by a vet to check for side effects like immune suppression or changes in bloodwork.
While the medication is highly effective in controlling allergic itching, long-term use carries the risk of chronic infections (due to immune suppression) and, in rare cases, the potential for cancerous growths. To ensure your dog stays safe on Apoquel, regular blood tests, including liver enzyme checks and immune function markers, are essential. These tests allow your vet to detect any early signs of complications, such as liver strain or significant changes in white blood cell count.
If your dog shows no adverse effects and their allergies are well-controlled, Apoquel can be continued indefinitely under veterinary supervision. However, it’s crucial to find the lowest effective dose that keeps your dog comfortable, as reducing the dose may minimize long-term risks.
💡 Expert Insight: If you’re concerned about the cumulative effects of Apoquel, consult with your vet about the possibility of intermittent dosing or alternating Apoquel with other treatments like Cytopoint to lessen the potential risks associated with continuous use.
Q: Is it true that Apoquel weakens a dog’s immune system over time?
Yes, Apoquel works by targeting and suppressing specific immune pathways involved in the allergic response. While this helps reduce itching and inflammation, it also means that over time, your dog’s immune system may become less effective at fighting off certain infections, particularly those affecting the skin, ears, and respiratory system.
Because Apoquel interferes with Janus kinase enzymes (which play a role in immune signaling), the medication can make your dog more susceptible to bacterial, fungal, and parasitic infections. Some dogs may experience recurring skin infections or an increase in yeast or bacterial overgrowth, particularly if they have existing vulnerabilities like allergies or a weakened immune system.
However, it’s important to note that not all dogs experience severe immune suppression on Apoquel. Regular veterinary check-ups are key to ensuring that your dog’s immune health remains stable while on the medication.
💡 Pro Tip: Keep a close eye on your dog’s skin, ears, and behavior for early signs of infection, such as redness, discharge, or frequent licking. If you notice these symptoms, alert your vet immediately, as these could indicate a weakening of the immune system due to Apoquel use.
Q: Can Apoquel be used with other medications like Cytopoint or steroids?
Yes, Apoquel can often be safely used alongside other medications like Cytopoint or steroids under the guidance of a vet. Combining treatments is sometimes necessary, especially for dogs with severe or chronic allergic conditions. For example, Cytopoint, which is an injectable medication, targets a specific protein involved in itching, providing relief without suppressing the immune system like Apoquel does. Some dogs may benefit from receiving Cytopoint injections while continuing Apoquel to manage both the intensity and frequency of their allergic symptoms.
Steroids, such as prednisone, may also be used for short-term relief during severe allergy flare-ups. However, due to the potential for side effects like immune suppression and organ strain, long-term steroid use is generally avoided unless necessary. Apoquel is often preferred over steroids because it has a more targeted immune suppression mechanism, meaning it typically has fewer systemic side effects.
💡 Expert Advice: Always consult your vet before combining Apoquel with other treatments. Your vet will help you develop a comprehensive allergy management plan that uses the most effective combination of medications with the least risk of side effects.
Q: Can Apoquel affect my dog’s liver or kidneys?
Long-term use of Apoquel may have an impact on your dog’s liver and, in some cases, their kidneys, but this varies by individual. The medication is processed through the liver, and while it’s relatively safe for most dogs, there is potential for elevated liver enzyme levels over time, indicating that the liver may be under some strain. In rare instances, the kidneys may also show signs of stress, particularly if the dog has pre-existing conditions affecting these organs.
It’s essential to perform routine blood tests every 6 to 12 months to check your dog’s liver and kidney function. By monitoring ALT (alanine aminotransferase) levels and other liver enzymes, your vet can detect early signs of liver damage and adjust the treatment plan as needed. If any issues arise, your vet might suggest lowering the dose of Apoquel or switching to an alternative treatment to protect your dog’s organs.
💡 Pro Tip: Provide a liver-supportive diet or supplements, like milk thistle or SAMe, after consulting your vet. These can help support liver health while your dog remains on Apoquel.
Q: Are there any withdrawal symptoms if I stop giving my dog Apoquel?
Apoquel is not associated with physical dependency, so there are no withdrawal symptoms if you stop giving it to your dog. However, discontinuing the medication can result in the return of your dog’s allergic symptoms, sometimes within 24 to 48 hours. This can lead to renewed itching, scratching, and discomfort, particularly if your dog suffers from chronic environmental or food allergies.
If you’re planning to stop Apoquel, it’s essential to have a replacement treatment lined up to manage your dog’s symptoms. Alternatives like Cytopoint, antihistamines, or topical treatments can help control the itching and inflammation. In some cases, a gradual tapering off of the medication may be advised, depending on how severe the allergies are.
💡 Expert Insight: Work closely with your vet to ensure that stopping Apoquel doesn’t cause a sudden flare-up in your dog’s symptoms. Your vet may recommend a multi-pronged approach, including diet changes and environmental modifications, to maintain allergy control without the need for Apoquel.
Q: Should I consider allergy testing before starting or continuing Apoquel?
Yes, allergy testing can be a valuable tool to better understand what’s triggering your dog’s symptoms and to possibly reduce the need for medications like Apoquel in the long run. There are two primary types of allergy testing: blood tests and intradermal skin testing. Both methods can help pinpoint specific allergens—whether they are environmental (such as pollen, dust mites, or molds) or food-related (such as chicken or wheat).
By identifying the underlying cause of your dog’s allergies, you may be able to implement targeted strategies like allergen avoidance or immunotherapy (allergy shots), which can reduce or even eliminate the need for Apoquel over time. Allergy testing is especially recommended for dogs with chronic or severe allergies who rely heavily on medication to stay comfortable.
💡 Pro Tip: Allergy testing is most effective when used alongside long-term allergy management strategies, such as hypoallergenic diets, environmental changes, and immune-modulating therapies. This can help reduce the medication burden on your dog over time.
My 12-year-old, 12-pound Yorkie has been on Apoquel for most of his life due to chronic itching. The cost of the medication over the years has been astronomical. Recently, a new veterinarian recommended a diet of boiled chicken and rice after he became ill. Since starting this diet, he hasn’t been itching at all, so I stopped the Apoquel—and he’s still itch-free.
I know a long-term diet of just chicken and rice isn’t nutritionally complete, but neither is long-term use of Apoquel ideal. I’m unsure whether it’s safe for him to continue on this limited diet, and I’m concerned about the potential health risks of feeding him only chicken and rice.
First off, it’s incredible that you’ve found relief from lifelong itching without Apoquel—especially after years of expense and limited results. That’s a huge discovery, and it likely points to an undiagnosed dietary sensitivity or food intolerance that was triggering the immune system.
That said, a diet of only boiled chicken and white rice is not nutritionally complete and can result in long-term deficiencies, especially in a 12-year-old dog whose metabolism and organ function require very specific support. The goal now is to identify the ingredient(s) your dog was previously reacting to and transition to a complete, balanced hypoallergenic or elimination diet.
📉 Why Chicken and Rice Isn’t a Long-Term Solution
🧠 Critical Insight: Chicken and rice diets are often used temporarily during digestive illness or food allergy trials. They are intentionally “bland” to reduce inflammation—but they should not exceed 2–3 weeks without supplementation or veterinary nutrition guidance.
🧪 What Likely Happened?
Your Yorkie may have had a **chronic food allergy** or intolerance (likely to an additive, protein source, or grain filler in commercial food), and the chicken/rice combo removed the irritant. This doesn’t mean chicken and rice is ideal—it just means it’s less inflammatory for him right now.
✅ What To Do Next: Safe Reintroduction or Full Hypoallergenic Diet
💬 Bonus Tip: Since he’s a senior, focus on joint support too—consider adding omega-3s from wild salmon oil and a small amount of pumpkin or chia seeds for fiber and inflammation control (pending vet approval).
