Located in picturesque central Massachusetts, the Westborough site was commissioned in 1979 and completed in 1983, after phasing out a supply and manufacturing facility in Worcester, Massachusetts, built in 1948. The site has evolved from primarily supplying parenteral (sterile injectable) products to becoming a multipurpose facility capable of supply and packaging of sterile injectables, topicals, and respiratory products. Over the years, many new technologies have been introduced to enhance production efficiencies and product quality.

The most well known products produced here are PULMICORT RESPULES? (budesonide inhalation suspension) and RHINOCORT AQUA? (budesonide). The Westborough Supply Site is a designated Foreign Trade Zone
and packages respiratory products for the Canadian market.

The Westborough Supply Site has completed a number of energy efficiency initiatives as a result of upgrades and retrofits that have saved the site an estimated 700,000 kilowatt hours per year.  These include the installation of energy-efficient light bulbs and programmable thermostats, improved controls for warehouse heating and cooling, upgrades to the chiller plant, including the installation of variable frequency drives, and the "What a Waste" program, which asks employees to turn off computers and lights when leaving for the day.


The Westborough Supply Site was awarded the 2008 ENERGY STAR.
