Consumer Advisory
GlaxoSmithKline (GSK) warns about a potential health risk associated with
long-term, excessive use of GSK’s zinc-containing denture adhesives
Super Poligrip ‘Original’, ‘Ultra Fresh’ and ‘Extra Care’.
This communication is to alert consumers to a potential health risk from long-term excessive use of zinccontaining
denture adhesives Super Poligrip ‘Original’, ‘Ultra Fresh’ and ’Extra Care’.
While zinc is an essential part of the diet, recent publications suggest that an excessive intake of zinccontaining
denture adhesives over several years may lead to the development of neurological symptoms
and blood problems such as anemia. Neurological symptoms may include numbness, tingling or
weakness in the arms and legs and difficulties with walking and balance.
Super Poligrip is safe to use as directed in the product label (see below). The majority of consumers
follow these directions. However, some consumers apply more adhesive than directed and use it more
than once per day. Therefore, as a precautionary measure to minimize any potential risks to these
consumers, GSK has voluntarily stopped the manufacture, distribution and advertising of these products.
GSK has discussed this situation with the FDA and no further action is required.
What consumers should do
If you 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 your health, you must:
1. Stop using the product.
2. Talk to your doctor.
3. Use a zinc-free alternative such as Super Poligrip ‘Free,’ Super Poligrip ‘Comfort Seal Strips’, or
Super Poligrip ‘Powder’.
People with ill-fitting dentures should seek help from their dental care professional, rather than
compensate for poorly fitting dentures by using excessive adhesive.
Polident Denture Cleanser tablets contain no zinc and are not affected by this announcement.
GSK will soon be introducing zinc-free versions of Super Poligrip ‘Original’, ‘Ultra Fresh’ and ’Extra Care’.
Zinc Free Formula will be clearly shown on the new packaging.
