HollisterStier

Since 1921, HollisterStier Allergy has partnered with allergists to help improve the lives of allergy patients. Our promise has always been to provide quality products, services, and resources to physicians and the patients they treat – and we remain committed to those ideals today.

Subcutaneous Immunotherapy, without Compromise

Our focus has always been on subcutaneous immunotherapy and bulk extracts. We create effective products to meet the specific needs of allergy specialists.

Phenol Free

We are proud to be the only manufacturer of phenol free allergy extracts in the U.S.

Products

Our product portfolio includes a number of unique offerings, including our Acetone Precipitated (AP) extracts, Mite, Histamine Dihydrochloride, 1:10 molds, and our exclusive line of Venoms. We also offer a variety of standardized and non-standardized extracts including grass, weed, and tree pollens, foods, and insects.

Testing Devices

We offer two unique skin test systems, ComforTen® Multiple Skin Test System & QUINTEST® Multiple Skin Test System. These devices are equipped with 1.2 mm stainless surgical steel tips that penetrate uniformly to obtain reproducible, well-defined reactions with minimal discomfort and trauma to your patients. Our diagnostic products include 5mL scratch vials of allergenic extracts, Histamine positive control, and 50% Glycerin negative control.

Patient-Focused

We are patient-focused in what we produce. We offer educational materials to help answer the questions your patients ask. For example, we created the BeeAware program to inform the public about VIT, demonstrating our commitment to both patients and allergists.
