Low Dose Allergen Therapy ​(LDA)

What is LDA?

Low Dose Allergen (LDA) therapy is an amazing option for treating most forms of allergies. This includes most forms of inhaled allergens (hayfever, pollen, pet dander, etc), food allergens (dairy, gluten, corn, etc), and even chemical sensitivities (perfumes, formaldehyde, etc).

History of LDA

LDA therapy stems from the research of Dr Leonard McEwen, a British physician who developed Enzyme Potentiated Desensitization (EPD) therapy out of research done in the 1960's. This was used quite successfully here in the U.S. until 2002 when it was banned by the FDA. Dr Butch Shrader continued Dr McEwen's research and developed a next-generation form of the same kind of therapy he named Low Dose Allergen (LDA) therapy.

How does it work?

With LDA therapy hundreds of different antigens (things people might be allergic to) are premixed and injected into the skin along with an enzyme called "beta glucuronidase." This enzyme tells your body to quit reacting to those antigens so much. It does this by raising the levels of the T-Regulator cells - the ones that calm down the immune response to that particular antigen.

Differences between LDA and "Regular Allergy Shots"

At first glance, LDA appears similar to "regular allergy shots." Both involve intermittent injections to treat allergic conditions. But that's where the similarities end...

Differences include:

  • Working by a different mechanism
  • MUCH lower doses (making it safer)
  • Hundreds of premixed antigens
  • No need for allergy testing
  • Shots given much less often
  • Given into the skin instead of under it
