Zinc has been touted as something to take to keep from getting a cold. Now we find that too much zinc can be harmful.
GlaxoSmithKline PLC will discontinue Super Poligrip with zinc, due to the risk that use of the denture adhesive may cause serious and potentially debilitating problems from zinc poisoning.
Super Poligrip Original, Ultra Fresh and Extra Care denture cream products will be removed from shelves and replaced with zinc-free versions, the British drug company announced on Thursday. The product change comes as the company faces mounting Poligrip lawsuits over health problems allegedly caused by zinc in the denture adhesive products. Excess levels of zinc entering the body from the denture cream could cause users to suffer neurological damage from zinc poisoning.
GlaxoSmithKline says that it is discontinuing the products due to the “health problems associated with the long-tern excessive use of our zinc-containing denture adhesive products.” However, the company said it still believes that the products are safe when used in recommended amounts. GlaxoSmithKline has maintained that users are only in danger when they use more than the recommended amount in order to compensate for ill-fitting dentures.
Eventually, GlaxoSmithKline says there will be zinc-free versions of all of the discontinued denture creams, but did not announce when those products would be available. There is already a Super Poligrip Free on the market, which does not contain zinc. The replacement products will be clearly marked as being zinc-free, the company said.
