The site was purchased in 1982 and has since undergone construction of two large-scale manufacturing plants which were designed to international pharmaceutical standards. These plants manufacture Sevelamer Hydrochloride and Sevelamer Carbonate, which are the active ingredients in Renagel® and Renvela® respectively. Our continuous manufacturing process allows us to produce large volumes of our product.

The Haverhill site is also a testing, label and packaging centre for Secondary Operations for the company’s rare disease, transplant and oncology products including its treatments for the rate genetic disorders; Pompe Disease, Fabry Disease, Gaucher Disease and MPS1.
