Frequently Asked Questions

Pet & Animal Atopic Dermatitis Treatment
Why should I choose PALLERGY rather than giving my pet allergy shots?

As a general rule, pet owners don’t like giving shots and pets don’t like receiving them. Oral drops are easy to administer, and because they have a higher safety profile, they can be given at home. No more worrying about giving your dog, cat or horse allergy shots!

What are the advantages of sublingual immunotherapy for dogs (cats, and horses)?
Open trial studies1,2 of canines have shown comparable efficacy between allergy shots for dogs and sublingual allergy drops for dogs. Drops have further been shown to be safer than shots and can be administered by pet owners at home. They are also often better tolerated by animals than allergy injections.
Are PALLERGY drops effective for dog itching?

If you observe your dog itching, it is most likely a manifestation of allergy. The same for itchy cats and horses. Allergies lead to atopic dermatitis which results in itchy skin that pets rub and paw at. This can lead to bald spots and hot spots (skin infections that are warm to the touch). For dog atopic dermatitis treatment, topical medications or antihistamines can take the edge off of your pet’s discomfort, but the problem tends to keep coming back until you address the underlying dog atopy (allergy).  Immunotherapy is the only treatment that has been shown to change the underlying allergy.  PALLERGY drops provide the benefits of immunotherapy without the hassle of allergy shots!

How long until my pet begins to achieve allergy relief?
Sublingual immunotherapy for cats, dogs and horses typically begins to bring symptom relief in the first several weeks of treatment. Each patient is unique, and individual results may vary. Consult your allergy veterinarian about your pet’s progress on the PALLERGY drops.
How do they work: dog, cat, horse allergy drops?
With allergy shots, the “serum” penetrates the skin and is assimilated into the bloodstream. With sublingual allergy drops, the serum absorbs under the tongue through the oral mucosa (mouth lining) and into the bloodstream.

The drops contain extracts of the most common allergens for pets in your area. As the pet’s body becomes accustomed or “desensitized” to these allergens, it learns to stop developing symptoms every time it encounters these allergens in nature.

If you’ve ever tried to give a horse, dog, or cat allergy shots, you will welcome the ease of sublingual administration!

If I am a pet owner, how do I find an allergy veterinarian or veterinary dermatologist to prescribe dog, horse, or cat allergy drops?

There are a couple options. To find out if there is an allergy vet near you who prescribes PALLERGY drops, contact us at 1-800-568-1180. OR, print this PDF and take it to the vet of your choice. It contains the information they need to prescribe PALLERGY drops for dog, cat, or horse allergy treatment.

How often do I need to give my pet allergy drops?
It’s easy. Just once per day (whether for cat, dog or horse allergy drops). Follow the dosing schedule included with your PALLERGY drops so you know how many drops to give with each daily dose.
How long has sublingual immunotherapy for pets been around?

Sublingual immunotherapy has been in use since the 1980s for humans. It is used broadly throughout the world and is especially well-used in Europe where it accounts for nearly half of all allergy immunotherapy in humans.4 Sublingual immunotherapy for horses, cats, and dogs is becoming increasingly popular in the U.S. as a safer, easier alternative to allergy shots.

Dog allergic? Cat Allergic? Horse allergic? Symptoms to watch for:

Skin-related allergy symptoms are the most common. This can translate into a horse itching himself constantly, an itchy dog prone to licking and chewing his paws, cats with feline acne as well as “hot spots” (bald, infected sores that are warm to the touch).

Other symptoms include wheezing and labored breathing (especially for horse allergies) as well as itchy, watery eyes. If you suspect allergies in your pet, PALLERGY drops can be prescribed by any veterinarian or veterinary dermatologist. Need a dog, cat or horse allergy vet? Contact PALLERGY.

If I travel with my pet, can I take PALLERGY drops with me?
Yes! PALLERGY drops are designed for portability. Simply slip them into your travel bag and take the drops on the road. And if you are traveling by flight, the dropper bottle is small enough to meet TSA requirements and make it through airline security checks.
What are PALLERGY drops made of?
Whether you have been prescribed horse, cat, or dog allergy drops, they all contain natural antigens suspended in a saline solution. The antigens are derived from common allergens (pollens, etc.) that your pet breathes in daily. The drops are free of the harmful side effects of synthetic medications.
My pet didn't used to be allergic? What changed?

Allergies can strike at any time in the span of a pet’s life. The immune system can be influenced by a number of factors including exposure to new allergens or an increased immune sensitivity to certain allergens that have always been in your pet’s environment. It is common for allergies to develop without much warning. If you find your cat, dog, or horse itching or dealing with other new symptoms, contact us to learn how your vet /veterinary dermatologist can start prescribing PALLERGY drops for your pet.

Why don't I need to get my pet allergy tested before I start treatment?

Studies comparing results of blood allergy tests on pets processed by multiple sources show significant inconsistency in results.3 Cat, horse and dog allergy testing frequently produces false negatives and false positives. Thus, if antigen mixes are based on test results, they may not properly address the scope of a pet’s allergies.


On the other hand, PALLERGY drops contain “allergen mixes” including all of the major allergens from a pet’s region and beyond. Thus, they will be covered against the full range of allergens they may come in contact with—not just those that may or may not show up on an allergy test.
