ALLERCEPT® Immunotherapy Treatments

Formulations are based on ALLERCEPT test results, the clinical history of the allergic animal, and geographical region. While every animal responds differently , most animals respond positively with relief in 3-6 months. Effective immunotherapy can be sustained safely throughout the life of the animal.

Along with ALLERCEPT Therapy Shots, Therapy Drops move immunotherapy from a last resort to the first choice for treating allergies.

Pioneering Veterinary Solutions

ALLERCEPT® test results provide the foundation for appropriate selection of allergens for specific allergy treatment. While steroid drugs are often used for short-term relief from the clinical signs of allergy, prolonged use of steroids can have serious side effects. Antihistamines, fatty acids, and shampoos can help, but typically provide only temporary and limited benefit. Immunotherapy is, by far, the safest, most effective treatment for pets with allergies.

ALLERCEPT immunotherapy  subcutaneous treatments are formulated based on ALLERCEPT test results, the clinical history of the allergic animal, and geographical region. Most animals respond positively with relief in 3 to 6 months.

Using Heska’s ALLERCEPT® allergen-specific IgE test to identify the important allergens, selection of allergens for sublingual treatment is performed in exactly the same manner as ALLERCEPT subcutaneous injections.

A series of specially-formulated treatment extracts in gradually increasing strengths, ALLERCEPT Therapy Drops are a palatable solution delivered in tiny amounts (2 pumps twice per day) under the pet’s tongue, and can be used in dogs that have had prior anaphylactic reaction to allergy shots. Sublingual therapy is successful in 60% of patients.

The Gold Standard in Allergy Technology

Heska is a world leader in innovative solutions for veterinary allergic disease holding many patents covering its allergy products. Heska’s unique, patented ALLERCEPT® program technology can detect as little as 10 picograms (trillionths of a gram) of allergen-specific IgE and can be used alone or in conjunction with conventional intradermal skin testing to accurately identify the source or sources of an allergic reaction. Unlike many other serum IgE tests that can mis-identify allergy sensitization based on the false-positive detection of allergen-specific IgG, Heska’s use of the high-affinity IgE receptor assures that false positives resulting from IgG detection do not occur.

Superior accuracy with ALLERCEPT IgE testing

Heska has patent rights for use of the high-affinity IgE receptor to measure allergen-specific IgE in the serum of both animals and humans. Heska’s ALLERCEPT Panels are validated for dogs, cats and horses. The simplicity of ALLERCEPT tests and treatment enables veterinarians in general practice to develop a core allergy practice, ensuring that many more allergic pets can be treated or referred to dermatology specialists.


ALLERCEPT Therapy Drops

Allergy shots are an ineffective treatment for some patients, due to lack of efficacy, difficulty in administration, or adverse reactions. Sublingual immunotherapy is an effective treatment for many patients who fail to respond to allergy shots.

The immune privilege of oral mucosa. Trends in Molecular Medicine in addition to offering immunotherapy injections to relieve the painful conditions of atopic dermatitis, Heska is the first to introduce a proprietary sublingual immunotherapy. Administered beneath the tongue, ALLERCEPT® Therapy Drops provide a simple way to provide effective relief.

Sublingual Mechanism

Sublingual immunotherapy allows specific antigens placed under the tongue to induce immunologic tolerance. Multiple mechanisms are involved and include the production of anti-inflammatory cytokines such as IL-10 and the induction of regulatory T-cells.

The mucosal area under the tongue is a privileged immunological site with unique characteristics. It consists of:
A physical barrier (mucosa)
Local immune cells
— High concentration of dendritic cells and T-cells
— Low concentration of mast cells, basophils and eosinophils
This allows for:
Differentiation of pathogens from harmless antigens
Muting of immediate and delayed allergic responses
Tolerance of mucosally-delivered allergens

Safety and Efficacy

Allergy drops have been used around the world in humans for more than 70 years and numerous studies validate both the safety and effectiveness. In fact, the World Allergy Organization has endorsed sublingual immunotherapy as a viable alternative to injection therapy in humans. The Cochrane Collaboration, the world’s most-trusted international organization dedicated to reviewing healthcare treatments, recently concluded allergy drop immunotherapy significantly reduced allergy symptoms and use of allergy medications. See RESEARCH section for more information.

Heska’s proprietary technology for sublingual administration was developed as a veterinary-specific variation based on a unique, time-tested and highly efficacious human protocol. In efficacy trials with hundreds of atopic dogs treated by veterinary dermatologists in varying geographic areas of the U.S. over the past 3 years, approximately 60% of dogs demonstrated substantial improvement in their clinical signs. Approximately 50% of dogs that showed no improvement or could not tolerate allergy shots, showed improvement when treated with allergy drops.

ALLERCEPT Therapy Drops can even be used safely in dogs that have experienced a prior anaphylactic reaction to allergy shots. If the patient has a history of prior anaphylactic reaction to allergy shots, please contact Heska’s Medical & Technical Consultants at 1-800-464-3752, option 5.
