GlaxoSmithKline Stops Making 3 Super PoliGrip Products Because of Zinc Risks

Main

The risk of zinc poisoning prompted GlaxoSmithKline to announce it would voluntarily stop manufacturing, marketing and advertising three zinc-containing Super PoliGrip denture cream products on February 18, 2010. The products affected by this announcement are: Super PoliGrip ‘Original’, ‘Ultra Fresh’ and ‘Extra Care’.

Glaxo said it is currently in the process of reformulating Super PoliGrip ‘Original’, Super PoliGrip ‘Ultra Fresh’ and Super PoliGrip ‘Extra Care’ to non-zinc formulations. The new versions should be in stores by Mid April 2010.

A small amount of zinc is necessary for a balanced diet. However, recent research suggests that long-term excessive use of zinc-containing denture creams like the Super PoliGrip products may lead to the development of neurological symptoms. These may include numbness, tingling or weakness in the arms and legs, difficulties with walking and balance and blood problems such as anemia.

Glaxo maintains that Super PoliGrip ‘Original’, ‘Ultra Fresh? and ‘Extra Care’ are safe to use as directed, but noted that some consumers may apply more adhesive than directed, or use it more than once per day. In a statement posted on its Web site, Glaxo said it stopped the manufacture, distribution and advertising of the three zinc-containing Super PoliGrip products as a precautionary measure to minimize any potential risks to consumers. The company also said it had discussed the matter with the Food & Drug Administration (FDA), and no further action is necessary.

According to Glaxo’s statement, consumers who have been using zinc-containing Super PoliGrip ‘Original’, ‘Ultra Fresh’ or ‘Extra Care’ for several years in greater amounts than directed on the package or more than once per day, or have concerns about their health, must:

  • Stop using the product.
  • Talk to their doctor.
  • Use a zinc-free alternative.

This action does not affect any zinc-free Super PoliGrip products, including Super PoliGrip ‘Free,’ Super PoliGrip ‘Comfort Seal Strips’, or Super PoliGrip ‘Powder’. These products remain available to consumers.
