Stallergenes makes all of its products in France, mainly just outside Paris (Antony), but also in Amilly (Loiret, centre of France).
The site in Antony hosts a production unit dedicated to manufacture NPPs (Named Patient Products) as well as a new production centre opened in 2008 devoted to manufacture of the active ingredient for sublingual tablets. The group has also opened in 2011 a new production unit, in Amilly, currently dedicated to the collection and processing of grass pollens used for the manufacture of allergen immunotherapy treatments and, most notably, the grass pollen sublingual immunotherapy tablet, Oralair®
This site hosts a unit dedicated to manufacture of NPPs (Named Patient Products) as well as a new production centre opened in 2008 devoted to manufacture of the active ingredient for sublingual tablets.
200 people are involved in manufacturing Stallergenes products along with their quality control in compliance with GMPs (Good Manufacturing Practices).

This is the biggest NPP production centre in the world. All of the starting materials are subject to chemical, bacteriological and immunological control. The production chain is fully automated, making it possible to manage the prescription of 3.5 million NPPs from all over the world every year, from their receipt through to shipment.

This 6 000 sq.m production centre has been operational since late 2007. Devoted to the manufacture of active ingredients for tablets, it represents an investment of 20 million euros and increases Stallergenes' production capacity tenfold.
This production site was designed in compliance with the European pharmaceutical standards of the European Medicines Agency (EMA)1 and is in the course of obtaining approval for compliance with the requirements of the Food and Drug Administration (FDA)2.
