Apoquel vs Zyrtec for Dogs
How do they compare, and which one is the best for your pup?
Which One is More Effective?
Both Apoquel and Zyrtec can provide relief from allergy symptoms in dogs. However, Apoquel is generally considered to be more effective in treating severe itching and inflammation caused by allergies.
In a study conducted by Zoetis, the manufacturer of Apoquel, the medication was found to be more effective than a placebo and provided significant improvement in itching, redness, and lesions in dogs with atopic dermatitis.
Zyrtec, on the other hand, is not as potent as Apoquel and may not be effective in treating severe allergy symptoms. It is best suited for mild to moderate itching and sneezing.
Which One has Fewer Side Effects?
Like any medication, Apoquel and Zyrtec can cause side effects in dogs. However, the side effects of Apoquel are generally more severe than those of Zyrtec.
Common side effects of Apoquel include vomiting, diarrhea, and decreased appetite. In rare cases, it can also cause infections, cancer, or liver problems. Zyrtec, on the other hand, can cause mild side effects such as drowsiness, dry mouth, and gastrointestinal upset.
Apoquel should not be used in dogs with a history of cancer or those that are immunocompromised. Zyrtec should not be given to dogs with kidney or liver disease.
Which One is More Expensive?
Apoquel is a prescription medication and is generally more expensive than Zyrtec. The cost of Apoquel can vary depending on the size and weight of your dog and the dosage prescribed by your veterinarian.
Zyrtec, on the other hand, is an over-the-counter medication and is relatively inexpensive. You can buy Zyrtec at your local drug store or online without a prescription.
What do vets prescribe for dog allergies?
We will explore what vets prescribe for dog allergies and how they work.
Antihistamines
Antihistamines are one of the most commonly prescribed medications for dog allergies. They work by blocking the release of histamines, which are responsible for allergic reactions. Antihistamines can provide relief from itching, sneezing, and other allergy symptoms.
Some of the most commonly prescribed antihistamines for dogs include:
- Benadryl (diphenhydramine)
- Zyrtec (cetirizine)
- Claritin (loratadine)
- Allegra (fexofenadine)
It is important to note that not all antihistamines are safe for dogs, and you should always consult with your veterinarian before giving your pet any medication.
Corticosteroids
Corticosteroids, also known as steroids, are powerful anti-inflammatory medications that can provide quick relief from allergy symptoms. They work by suppressing the immune system and reducing inflammation in the body.
Some of the most commonly prescribed corticosteroids for dogs include:
- Prednisone
- Prednisolone
- Dexamethasone
While corticosteroids can be effective in treating allergies, they can also have serious side effects if used for long periods. Your veterinarian will carefully monitor your dog’s response to the medication and adjust the dosage as needed.
Immunotherapy
Immunotherapy, also known as allergy shots, is a long-term treatment option for dogs with allergies. It works by exposing your dog to small amounts of the allergen over time, gradually building up their immune system’s tolerance to the substance.
Immunotherapy is usually reserved for dogs with severe allergies that do not respond well to other treatments. It can take several months to see results, but the benefits can last for years.
Topical Treatments
Topical treatments, such as shampoos and sprays, can provide relief from itching and other skin irritation caused by allergies. They work by moisturizing and soothing the skin and reducing inflammation.
Some of the most commonly prescribed topical treatments for dogs with allergies include:
- Hydrocortisone cream
- Calamine lotion
- Aloe vera gel
Your veterinarian may also recommend a medicated shampoo to soothe your dog’s skin and reduce itching.
FAQs about Zyrtec for dogs
What is Zyrtec and How Does it Work?
Zyrtec, also known as cetirizine, is an antihistamine that works by blocking the production of histamine in the body. Histamine is a natural chemical that is released by the immune system in response to an allergen. This can cause a variety of unpleasant symptoms, such as sneezing, itching, and hives. By blocking histamine, Zyrtec can relieve these symptoms and help your dog feel more comfortable.
What is the Correct Zyrtec Dosage for Dogs?
The correct Zyrtec dosage for dogs depends on their weight. The general guideline is to give your dog 0.5 mg of Zyrtec per pound of body weight, once a day. For example, if your dog weighs 20 pounds, you would give them 10 mg of Zyrtec per day. It’s important to stick to this dosage and not exceed it, as giving your dog too much Zyrtec can lead to side effects.
What are the Side Effects of Zyrtec in Dogs?
While Zyrtec is generally safe for dogs, it can cause side effects in some cases. The most common side effects are drowsiness and lethargy. Some dogs may also experience vomiting, diarrhea, or loss of appetite. If your dog experiences any of these symptoms after taking Zyrtec, you should stop giving it to them and consult with your veterinarian.
Can I Give My Dog Zyrtec if They Are Taking Other Medications?
If your dog is taking other medications, you should check with your veterinarian before giving them Zyrtec. Zyrtec can interact with some medications and cause adverse effects.

How Should I Administer Zyrtec to My Dog?
Zyrtec is available in tablet form, and it can be given to your dog either with or without food. It’s important to make sure your dog swallows the tablet whole, rather than chewing or crushing it, as this can affect the way the medication is absorbed into their system. You can also try hiding the tablet in a small piece of food to make it easier for your dog to take.
When Should I Give Zyrtec to My Dog?
Zyrtec can be given to your dog as needed to treat allergy symptoms, or on a daily basis to help prevent them from occurring in the first place. It’s best to give Zyrtec at the same time each day, to help maintain consistent levels of the medication in your dog’s system. If you’re not sure when to give Zyrtec to your dog, or how often, you should consult with your veterinarian.
Is Zyrtec Safe for All Dogs?
While Zyrtec is generally safe for most dogs, it may not be appropriate for every dog. Dogs with certain medical conditions, such as liver or kidney disease, may not be able to tolerate Zyrtec or may require a lower dosage. Additionally, pregnant or nursing dogs should not be given Zyrtec, as the medication can potentially pass through to their puppies. Always consult with your veterinarian before giving Zyrtec to your dog, especially if they have any underlying medical conditions.
What Should I Do If My Dog Experiences an Allergic Reaction?
If your dog experiences an allergic reaction, it’s important to seek veterinary care immediately. Symptoms of an allergic reaction can include difficulty breathing, swelling of the face or limbs, hives, and vomiting or diarrhea. Your veterinarian may recommend additional medications or treatments to help manage your dog’s symptoms and prevent further complications.
What Should I Do If I Accidentally Give My Dog Too Much Zyrtec?
If you accidentally give your dog too much Zyrtec, you should contact your veterinarian right away. Giving your dog too much Zyrtec can cause side effects such as drowsiness, lethargy, and vomiting. Your veterinarian may recommend monitoring your dog for symptoms or taking additional steps to manage their condition, depending on the severity of the overdose.
Can Zyrtec Help with Other Health Issues in Dogs?
While Zyrtec is primarily used to treat allergy symptoms in dogs, it may also have some benefits for other health issues. Some veterinarians may recommend using Zyrtec to help manage itching and inflammation associated with skin conditions, such as atopic dermatitis. However, the use of Zyrtec for these purposes is not yet well-established, and you should always consult with your veterinarian before using any medication for off-label purposes.
What Are Some Other Ways to Help Manage Allergies in Dogs?
In addition to using medications such as Zyrtec, there are a variety of other ways to help manage allergies in dogs. Some strategies you can try include reducing your dog’s exposure to allergens by cleaning their bedding and living area frequently, using air purifiers, and avoiding outdoor areas with high pollen counts. You can also try using natural remedies such as probiotics or omega-3 supplements to help support your dog’s immune system and reduce inflammation.
Are There Any Alternatives to Zyrtec for Treating Allergies in Dogs?
Zyrtec is not the only medication available for treating allergies in dogs. Other antihistamines, such as Benadryl and Claritin, can also be used to manage allergy symptoms in dogs.
