Improving Quality of Life Through Allergy Extracts

HollisterStier Allergy has remained committed to supplying high-quality allergy products for over 100 years. We’re eager to see healthcare professionals improve the quality of life for allergy sufferers worldwide and are thankful for the role products play.

When purchasing allergy extracts from HollisterStier Allergy you can expect:

  • No Phenol: Our glycerin extracts do not contain phenol in the extraction process. By helping prevent denaturation, these products have an increasingly stable shelf life.1
  • High Quality: From holding ourselves to a higher constraint than the FDA requires for standardized cat hair to creating the only dog hair extract that meets Practice Parameter dosing recommendations, we push ourselves to make the highest quality products possible.
  • Highly Regulated: Our processes are overseen by both CDER and CBER, providing extra confidence in the quality and safety of our products.
