In a recent Sunday Housecall called Growing Evidence that Zinc Nasal Spray Can Damage Smell on FoxNews, Dr. Isadore Rosenfeld says, ‘Zinc nasal spray is ineffective … In addition, if you use it frequently, it can interfere, sometimes permanently, with your sense of smell.’

A common over-the-counter homeopathic cold remedy, zinc nasal spray is often reached for to ‘cure’ colds. Instead of risking the use of such a product, Dr. Rosenfeld recommends staying at home, drinking fluids, getting rest, and waiting for the sypmtoms to subside on their own in a couple days.
