Parker Waichman Alonso LLP Files Another Lawsuit Against GlaxoSmithKline Alleging Person Stricken With Neuropathy From Zinc In Super PoliGrip

GREAT NECK, N.Y. — Parker Waichman Alonso LLP announced Oct. 7 that it has filed a lawsuit against GlaxoSmithKline and its subsidiaries on behalf of a Georgia woman who was diagnosed with neuropathy attributed to the use of Super PoliGrip denture adhesive cream. The lawsuit is the latest of several filed by Parker Waichman Alonso on behalf of the victims of zinc-containing denture creams.

According to the latest complaint:

Glenda Brown Avera, 57, received dentures six years ago, and has used Super PoliGrip. Avera stopped using the denture adhesive cream after she was diagnosed with neuropathy caused by excess zinc, and resulting copper depletion, attributable to Super PoliGrip. She now suffers from profound and permanent neurological injuries, which have left her unable to perform her normal, customary, and daily activities. The lawsuit alleges that GlaxoSmithKline misled consumers about the product’s risks and failed to provide adequate warnings about the zinc in Super PoliGrip or adequate instructions to prevent deviation from accepted use.

According to the complaint, Super PoliGrip contains a form of zinc which is bonded to an unknown formulation. A small amount of zinc is necessary for a balanced diet. However, being exposed to an excessive amount of zinc can result in copper depletion and serious negative adverse neurological effects. In August 2008, the peer reviewed journal “Neurology” reported on four patients suffering from neuropathy and other neurological symptoms typical of zinc poisoning and copper depletion. The article specifically linked excess zinc in Super PoliGrip to “profound neurologic disease” in the patients reviewed.

Avera's lawsuit, along with dozens of others, has been consolidated for centralized and coordinated pretrial proceedings in the Denture Cream Products Liability Litigation in the U.S. District Court for the Southern District of Florida, Miami Division, before Judge Cecilia Altonaga (MDL No. 2051). In an order filed on July 13, 2009, Judge Altonaga appointed Andres F. Alonso, a partner with Parker Waichman Alonso, as co- lead counsel to the Plaintiffs' Steering Committee in the Denture Cream Products Liability Litigation. Discovery in the litigation is now under way and depositions are currently being scheduled.

  • The new warning about zinc in Super Poligrip is not adequate. The warning states that swallowing small amounts of Super Poligrip is not harmful; however, the warning is misleading and might be doing more harm than good. Ingesting even small amounts of Super Poligrip has been found to be harmful; people who used normal amounts of Super Poligrip, and who swallowed small amounts of the product, suffered from zinc poisoning and neurological problems.
