About HAL Allergy
Expertise in Allergen Immunotherapy
HAL Allergy started as a small laboratory in Haarlem, the Netherlands. On request of several local general practitioners, extracts were prepared on a named patient basis to treat allergic reactions. The core business of HAL Allergy was, and still is, the treatment of allergies with allergen immunotherapies. Patients’ well-being is always our top priority.
In the 1970’s HAL Allergy grew to a mid-sized laboratory and expanded into the German market. Germany soon developed into a major export country for HAL Allergy products.
