Zicam is sold in various forms - nasal spray, losenges or cough syrups. Zicam Cold Remedy products have alleviated countless numbers of colds for millions of satisfied consumers. There has been recent controversy regarding some side effects of Zicam (loss of sense of smell) that has caused Zicam, due to pressure from the FDA, to voluntarily withdraw it's nasal spray product off the market. Since Zicam Cold Remedy intranasal Cold Remedy products were first introduced in the market in 1999, more than 35 million retail units representing over 1 billion doses have been sold, and the cumulative body of scientific and medical evidence compiled over those years has demonstrated both the safety and efficacy of Zicam intranasal cold remedy products under conditions of ordinary use - according to the instructions on the packet. Excessive use may cause temporary symptoms of loss of smell or sore nose, so caution should be paid to the instructions on the label. The company announced on June 17th, that it will comply with the FDA request but will seek a meeting with the FDA to defend the safety of its products.
