What is Hydroxyzine Pamoate?

Hydroxyzine Pamoate is an antihistamine used for the treatment of allergies in dogs and cats. Hydroxyzine Pamoate requires a prescription from your veterinarian, and is sold per capsule.

For:

Dogs and Cats

Benefits:
  • Effective against hives, itching, and rashes
  • Can be used as a mild sedative or tranquilizer for anxious dogs
How it Works:

Hydroxyzine blocks the effects of histamine in the body. Hydroxyzine also depresses activity of the central nervous system and is also used to treat anxiety disorders and tension in stressful situations.

Cautions:

It should not be used in pregnant or nursing animals. Hydroxyzine may cause drowsiness. Be sure to tell your veterinarian about any health conditions or other drugs your dog or cat may be taking.

Brand Name:

Vistaril (Pfizer)

Generic Name:

Hydroxyzine Pamoate

What should I discuss with my veterinarian before giving hydroxyzine to my pet:

Tell your veterinarian if your pet has heart, liver or kidney disease. Tell your veterinarian if your pet is pregnant or lactating.

What is the most important information I should know about hydroxyzine:

Hydroxyzine pamoate (generic for Vistaril) is not FDA approved for use in veterinary medicine; however, it is a commonly accepted practice for veterinarians to use this medication in dogs and cats. Hydroxyzine pamoate is available as 25mg and 50mg capsules. The usual dose of hydroxyzine in dogs is 1mg per pound every 6 to 8 hours. The usual dose in cats is 5 to 10 mg per cat every 8 to 12 hours. Hydroxyzine may cause drowsiness or dizziness.

How should this medication be given:

Follow the instructions on the prescription label. If you do not understand these directions ask your pharmacist or veterinarian to explain them to you. Store hydroxyzine at room temperature away from moisture and heat.

What happens if I miss giving a dose:

Give the missed dose as soon as you remember. However, if it almost time for the next regularly scheduled dose, skip the missed dose and give the next one as directed. Do not give a double dose of the medication.

What should I avoid while giving Hydroxyzine:

Hydroxyzine can cause drowsiness and dizziness.

What are the possible side effects of Hydroxyzine:

Seek emergency veterinary medical attention if your pet experiences any signs of an allergic reaction (hives; difficulty breathing; swelling of the face, lips, tongue, or throat). Keep giving Hydroxyzine and talk to your veterinarian if your pet develops any of these less serious side effects; dizziness, drowsiness, or confusion; blurred vision or dry mouth; nausea or vomiting. Talk to your veterinarian about any side effect that seems unusual or that is especially bothersome to your pet.

Rated 5 out of 5 by from cough and itchy skin Our dog has suffered from allergies for a long time. Vets have told us that is was kennel cough and gave us some powerful antibiotics. Did not help at all.After tireless efforts and no results we gave up until our neighbor recommended a vet he goes to. He put our dog on this product and Omega 3 vitamins. Our dog is at peace now - his coughing is just about non exsistent and the scratching has stopped. This is the best treatment for our dog. He can live a better life. He is not bothered by any side effects.

Rated 5 out of 5 by from Oscar and Poko Recommend Like many doxxies, my poor babies have seasonal allergies. This product has been helpful in toning them down. The boys sneeze less and, with the help of doggie shirts, Oscars summer rash is under control.

Rated 4 out of 5 by from works well on itchy skin This drug works pretty well for my dog's itchy skin. I found that it works much better when given with a fish oil supplement (omega 3 fatty acid pill). After about a month, I can see a huge difference in my dog's skin. She is not as itchy and her coat is much more silky. Her skin is not as red and her rashes have cleared up completely! I just hope it stays this way, although the vet did say that she will most likely be on this medication for the rest of her life. At least its quite inexpensive through 1-800-petmeds!

Rated 4 out of 5 by from Can be helpful All those with "allergic" dogs - please be aware that most dog foods have high carb content which promotes yeast which leads to itchiness, paw licking, red paws, irritation, ear infections, dull coat, hot spots - any or all of these things! So FIRST make sure that your dog is not consuming high carbs/low protein. You should generally be feeding your dog about 35% protein. Many popular and/or lowcost foods are only about 20-22%! Change over gradually (a week or two) and then most people notice improvement in about 4 weeks or so, and things will just get better from there! Organic dog food is NOT necessarily good. Protein content is very important, with carbs about 40% maximum. (Most better foods are NOT at the big box stores, by the way.) Good luck! Many of you will find that this is what your dog has needed! Enjoy!

Rated 5 out of 5 by from Works wonders for calming The vet gave us this due to our Dobie being nervous (had 4 different, terrible parents--starved & abused) when our schedules change or the weather gets windy, etc. They work sooo well for him. Sleeps peacefully yet on walks or at the dog park he plays & enjoys himself to the fullest. Would recommend for any "high strung" or abused or nervous pet.

Rated 4 out of 5 by from Helpful Relief After using otc allergy medication, my vet changed me to Hydroxyzine. The first two weeks were like a miracle; after that Zoe became accustomed to it and began scratching and licking again, but it definitely does cut down on the amount of her itching. The sensitive skin shampoo and frequent baths also help. I have found that boredom also contributes to more licking.

Rated 4 out of 5 by from Almost a success I have a two year old Husky mix with airborne allergies, I used benadryl last year for her allergies but this year it wasn't working, her vet gave her hydroxyzine and it makes her more comfortable but doesn't completely relieve her of her itchiness.

Q&A

How long does it take to work?

I'm planning to try this with my black lab this Halloween. If I expect trick or treaters at 6:00 pm should I give him the dose at 500 pm? Is that plenty of time for it to start working?
Asked by: gotpickled
Yes, Hydroxyzine should start to have its effect within an hour of your dog receiving his dose.

Can I take hydroxyzine pamoate 25mg mix with Advil pm?

Asked by: Maria
Hydroxyzine is an antihistamine. Advil PM also contains an antihistamine, which makes you drowsy and helps put you to sleep. It is not recommended to take two sedating antihistamines together, as this can cause increased sedation. Only take one or the other, and not both together.

can humans take this medicine

Asked by: ann
Yes this can be taken by humans. I've been prescribed this Hydroxyzine Pamoate 25mg since returning from combat operations in the Gulf. I have an unexplainable rash, in spots all over my body, that is very irritable in the summer months. This drug has helped me tremendously with the itching problem and it also assists with the sometimes anxiety issues. Personally I highly recommend this for human consumption!! But I'm on this site now looking to see if this drug will help my dog and his itching problem

Can I give Benadryl with hydroxyzine.

I have a 5month old Jack Rat and she has sever allergies. She is taking 10 mg of hydroxyzine according to her weight and it is helping, but still has rashes and itching.
Asked by: Teacher
No. Both Benadryl and Hydroxyzine are anti-histamines. Your pet could experience severe side effects such as dry mouth, a rapid heart rate and increased blood pressure well as trouble urinating. Please consult with your veterinarian to report your pet is still itching and has a rashes.

Hydroxzyzine & pregnancy

My dog was taking Hydroxzyzine 50mg 2 x a day- We bred her at the end of July, todate we can only assume she Is pregnant....I seen the warning and am wondering if Ipossible I've caused damage to pups possibily developing....I will stop giving her allergy med but now Im concerned, as she's been taking for the past three weeks in which she may have become pregnant It should not be used in pregnant or nursing animals. Hydroxzyzine may cause drowsiness. Be sure to tell your veterinarian about any health conditions or other drugs your dog or cat may be taking.
Asked by: sharkerisme
You need to call your veterinarian about this. He can determine if there is any damage that may have occured if in fact your dog is pregnant. Thanks for your question.
