Zicam nasal gel can destroy or severely damage your sense of smell according to a warning issued by the Food and Drug Administration. The warning only applies to the nasal products, which I actually use. The warning was based on 130 complaints received by the FDA from people and their doctors stating that following use of those products people suffered a condition called "ansomia," which is a loss of the sense of smell.
Since 1999, the maker of Zicam has payed $12 million to settle over 300 lawsuits. However, they have never recalled the drug. In fact, even after this FDA warning, the maker of Zicam refuses to recall the drug. Nevertheless, before Zicam markets their drug again they will have to gain FDA approval.
Like I have said, I used this exact product and have not noticed any problems- but then again, I have not been looking. I wonder how many people have not noticed and are suffering from loss of smell. Hopefully the makers of Zicam recall their product and find a way to issue it again in a safe form.
