Overview: Hydroxyzine, a common antihistamine used for anxiety and allergic reactions in humans, can sometimes be prescribed for dogs. However, administering it to your canine companion requires caution and careful consideration. This article will delve into the potential benefits and risks of using hydroxyzine for dogs, providing essential information to help you make informed decisions about your pet’s health.
What is Hydroxyzine?
Hydroxyzine is a medication classified as a non-sedating antihistamine. It primarily works by blocking the action of histamine, a chemical released by the body during allergic reactions. Histamine can cause various symptoms, including itching, sneezing, and swelling. By preventing histamine from binding to its receptors, hydroxyzine helps alleviate these symptoms.
Hydroxyzine is available in various forms, including tablets, capsules, syrup, and injectable solutions.
What are the Potential Benefits of Hydroxyzine for Dogs?
While not a first-line treatment, hydroxyzine can be a valuable tool for managing certain conditions in dogs, including:
- Anxiety: Hydroxyzine can be used to help reduce anxiety in dogs experiencing situations like vet visits, thunderstorms, or separation anxiety. It has calming effects, helping them relax and cope with stressful situations.
- Allergies: Hydroxyzine can provide relief from allergic symptoms like itching, hives, and swelling in dogs with allergies to food, pollen, or other environmental allergens.
- Motion Sickness: Some dogs experience motion sickness during car rides or boat trips. Hydroxyzine can help alleviate nausea and vomiting related to motion sickness.
- Itchiness: In some cases, hydroxyzine can be used to treat severe itchiness associated with skin conditions like atopy, flea allergies, or contact dermatitis.
It’s important to note that hydroxyzine is not a cure for these conditions, but rather a tool to help manage their symptoms.
Is Hydroxyzine Safe for Dogs?
While hydroxyzine can be safe for dogs when prescribed and administered appropriately, it is essential to be aware of potential side effects and risks.
Potential Side Effects:
- Sedation: The most common side effect of hydroxyzine in dogs is sedation. This can range from mild drowsiness to more severe lethargy.
- Dry Mouth: Hydroxyzine can lead to dry mouth in dogs. This can be uncomfortable and might affect their appetite.
- Gastrointestinal Issues: Some dogs may experience gastrointestinal upset, including vomiting, diarrhea, or constipation, when taking hydroxyzine.
- Increased Appetite: Hydroxyzine can sometimes cause an increase in appetite in dogs.
- Dizziness: Some dogs may experience dizziness or unsteadiness while on hydroxyzine.
- Hypersensitivity: In rare cases, dogs may develop a hypersensitivity reaction to hydroxyzine. This can manifest as hives, swelling, difficulty breathing, or even anaphylaxis.
Potential Risks:
- Drug Interactions: Hydroxyzine can interact with other medications your dog may be taking. It’s crucial to inform your veterinarian about all medications your dog is currently on.
- Overdose: Giving your dog too much hydroxyzine can be dangerous. Always follow your veterinarian’s instructions for dosage and frequency.
- Individual Reactions: Dogs can react to medications differently. It’s essential to monitor your dog closely for any adverse reactions while on hydroxyzine.
When Should Hydroxyzine Be Avoided?
There are certain situations where hydroxyzine should be avoided in dogs:
- Pregnancy and Lactation: Hydroxyzine should not be given to pregnant or lactating dogs, as its safety in these situations hasn’t been established.
- Liver or Kidney Problems: Dogs with pre-existing liver or kidney problems may not be able to process hydroxyzine properly.
- Certain Medical Conditions: Hydroxyzine may not be suitable for dogs with specific medical conditions, such as glaucoma, heart disease, or urinary retention.
How is Hydroxyzine Administered to Dogs?
Hydroxyzine for dogs is typically administered orally, either in tablet or liquid form. The dosage and frequency will depend on the dog’s individual needs, as determined by your veterinarian. Your vet may also recommend alternative administration methods like injection or topical application in specific cases.
What to Do if You Think Your Dog Has Taken Too Much Hydroxyzine
If you suspect your dog has ingested more hydroxyzine than prescribed, contact your veterinarian or the ASPCA Animal Poison Control Center immediately. Immediate medical attention may be necessary.

Alternatives to Hydroxyzine
In some cases, your veterinarian may recommend alternative medications for anxiety, allergies, or other conditions instead of hydroxyzine. Some potential alternatives include:
