Leading in allergy treatment

HAL Allergy Group (HAL Allergy) is a modern leader and innovator in the field of biopharmaceuticals and located at the Bio Science Park in Leiden, The Netherlands. Our core businesses are in the area of allergy diagnostic and treatment as well as in the area of contract manufacturing with focus on the production of biopharmaceutical products for preclinical and clinical studies. With offices in major European countries, HAL Allergy is one of the European top players, particularly in the field of allergy.

Established in 1959 we have long experience in developing, producing and selling allergy therapies that may reduce or erase allergic reactions. The allergy therapies are used against common allergies such as hay fever, house dust mites allergy and allergic reactions towards wasp or bee stings.

HAL Allergy originally stems from 'Haarlems Allergenen Laboratorium', a Dutch company set up in Haarlem. We take more than a little pride in our international leading role in the production of allergen extracts, both for therapeutic and diagnostic purposes.

HAL Allergy is a subsidiary of the family owned Droege Group International AG.
