The FDA says about 130 consumers have reported a loss of smell after using Zicam products since 1999.
Manufacturer Matrixx Initiatives is facing lawsuits over the product, but says on its Web site: "No plaintiff has ever won a court case, because there is no known causal link between the use of Zicam Cold Remedy nasal gel and impairment of smell."
Calls placed to the Scottsdale, Ariz.-based company were not immediately returned.
