Horse Immunotherapy

Allergen Specific Immunotherapy (ASIT) is designed for animals who are still suffering from an allergic reaction even when they are not subjected to the irritant.

Advantages of ASIT:

  • Effective (60-70% of animals experience positive results)

  • Economical when compared to chronic drug therapy

  • User-friendly (less frequent administration than drugs)

  • No concern with pre-racing or pre-performance withdrawal times

In some horses, a beneficial response to ASIT may be seen within 2-3 months of treatment. ASIT should always be continued for at least one year. Some horses may require lifetime administration of ASIT.

Negative reactions to ASIT are uncommon. These include:

  • Local reactions at injection sites which usually regress in 1-2 days

  • Intensified clinical signs

  • Hives

Serious reactions such as anaphylaxis are extremely rare.  Negative reactions are treated according to symptom.
