Shirley, NY - Due to renovations to our Shirley, NY factory, supplies of Adequan® i.m., the only polysulfated glycosaminoglycan (PSGAG) approved by the Food and  Drug Administration (FDA), are expected to be limited over the coming  months.

Our factory in NY has undergone a significant renovation to meet enhanced quality standards and address observations of the FDA.  This has resulted in the depletion of our existing inventories.  We have carefully managed supply to allocate inventory optimally, but the product will be out of stock for a short period of time. We expect to resume shipments of the 5 mL in early July, followed by the 50 mL in August. 

We appreciate the patience and loyalty of our customers during this supply interruption. Luitpold plans to continue our active role in supporting the veterinary and horse owner industry through sponsorships and educational programs. Our commitment to the health and well-being of these magnificent animals remains our primary focus. 

Since approved for use in the horse by the FDA in 1984, no other PSGAG has been developed to treat non-infectious degenerative and/or traumatic joint dysfunction and associated lameness of the carpal and hock joints in horses.  There is no generic Adequan® i.m. product available anywhere in the world and we recommend careful evaluation of any alternative product claims to ensure safety and efficacy.

Our Territory Managers will continue to communicate these updates to both their veterinary accounts as well as many of the horse owners they meet at our sponsored events.
