FDA Urges Removal of Zinc from Denture Creams, Citing Nerve Damage Studies

Photo Courtesy - Getty Images(WASHINGTON) -- After receiving more than 360 complaints that long-term overuse of the popular denture cream Fixodent caused serious nerve damage, the Food and Drug Administration last week urged denture cream makers to remove zinc, modify package labels and conduct further research of risks.

As ABC News reported earlier this month, excessive long-term use of zinc-containing denture creams like Fixodent may cause serious and irreversible neurological damage. Poligrip, the other leading denture cream, no longer contains zinc.

An exclusive ABC News investigation also uncovered that a paid consultant to Proctor & Gamble, maker of Fixodent, did not disclose a possible conflict of interest when he peer-reviewed a scientific study of four patients that suggested a link between an overuse of denture cream containing zinc and nerve disease.

In a Notice and Recommendation Action dated Feb. 23, 2011, the FDA wrote: "Although zinc is an essential nutrient, overexposure may result in zinc toxicity. We are notifying all manufacturers of denture adhesives and asking for their assistance in dealing with this public health issue."

Consumers most at risk are those "using excessive amounts of the products over extended periods of time; people with poor fitting dentures; and people who are unable to read or understand product labeling," the FDA wrote.

It "strongly recommends" manufacturers of denture creams that contain zinc, including Fixodent, to consider "replacing zinc with an ingredient that presents less health risks in situations of overuse."

Proctor & Gamble on Monday told ABC News that it is in active discussions with the FDA on this topic, that it takes the recent notice very seriously, and that it is "carefully considering the FDA's recommended actions."

The company also mentioned that it has already changed its product label to caution customers about overuse of the product, and said it is "always looking for new and improved formulas as we strive to improve our products."

Zinc Helps Tame the Common Cold

Photo Courtesy - Getty Images(OXFORD, England) - A recent systematic review of several studies has determined that zinc is indeed helpful for shortening and reducing the effects of the common cold, although some medical professionals remain skeptical.

The Cochrane Library announced Tuesday that a review of 15 studies that examined a combined 1,300 patients found that a zinc supplement is efficient if taken by healthy individuals within 24 hours after symptoms begin.

The review also found that taking a zinc supplement reduced the risk of developing a cold by 36 percent. Others, however, are not so sure.

ABC News' chief health and medical editor, Dr. Richard E. Besser, responded to Thursday's findings.
 
"The current state of the science makes it impossible to say whether zinc works," Besser said. "I am most skeptical of zinc as a means of preventing colds in people who are otherwise well-nourished."

Dr. Besser said he does not recommend zinc for either the prevention or treatment of colds. Rather, he recommends washing your hands and using alcohol-based sanitizers frequently for prevention. Although he said most over-the-counter products are ineffective for treatment, Dr. Besser said acetaminophen and ibuprofen are effective pain and fever medications. Nasal decongestants, tissues, salt water nose drops and petroleum jelly can also help to ease affects of the common cold.
