GlaxoSmithKline Plc., has resolved over 100 lawsuits and has paid out more than $120 million in claims against the line of denture cream products that include Super Poligrip Original, Ultra Fresh and Extra Care for zinc related health risks.
Many of the lawsuits claimed that the manufacturer knew about the dangerous side effects due to the high levels of zinc in their products and failed to warn consumers of these dangers. Glaxo attorneys argued that consumers subjected themselves to the increased levels of zinc by applying the denture cream more than once a day.
Researchers have found that heavy use of denture adhesives containing zinc can cause neurological problems including nerve damage that may result in memory loss, muscle weakness in the arms and legs and loss of balance.
Glaxo has since agreed to remove zinc from its line of denture cream products.
Glaxo has been hit hard by sales-practice and product liability lawsuits concerning its diabetes drug Avandia, and its antidepressant Paxil. GSK has reported its second profit loss in three quarters due to legal costs.
