Zicam and Cold-Eeze are over-the-counter homeopathic nasal solutions that claim to reduce the symptoms and duration of the common cold. Zicam is applied directly to the nasal surface with either a spray or gel swab and Cold-Eeze is a nasal spray. Both products contain the active ingredient Zincum Gluconicum, sometimes referred to as Zinc Gluconate. Some medical personnel believe that this ingredient causes a caustic action on the nasal passages and leads to a loss of smell (known as “anosmia”). According to Zicam labeling, the product is clinically proven to reduce the duration of the common cold and the severity of cold symptoms.

Intranasal zinc solutions were first used in 1936-1937 to prevent polio but it was found to be unsuccessful and to cause a loss of smell in some instances. The FDA does not test for safety or efficacy on cold remedies like Zicam and Cold-Eeze that contain soluble zinc. Nasal sprays containing zinc compounds have been shown to severely damage or destroy one's ability to smell. Inhibiting the sense of smell, in turn, greatly decreases the ability to taste. It has been known for decades that zinc compounds can cause nasal nerve damage. Despite awareness of these dangers, neither Zicam or Cold-Eeze provided adequate warnings to the public.

If you have experienced any adverse effects after using a nasal spray containing zinc, it is recommended that you see your doctor. If you or a member of your family may be suffering from Anosmia and have experienced loss of smell or taste from the use of Zicam or Cold-Eeze, you may want to consider your potential legal claim for this loss.

After the Dow Jones reported the FDA was investigating consumer complaints regarding the use of Zicam and anosmia, the manufacturer, Matrixx Initiatives, Inc., allegedly responded by issuing a press release that indicated that it was not aware of any FDA inquiry into Zicam's safety. According to the company, all Zicam products are manufactured and marketed adhering to FDA guidelines on homeopathic medicine.
