NasalCrom works differently from other over-the-counter allergy products and brings relief from chronic allergy symptoms before they begin. When used before exposure to many common allergens, NasalCrom can prevent the onset of nasal allergy attacks and build protection against future symptoms as long as you continue to use it as directed. It contains no steroids and is safe to use with other allergy medications. NasalCrom does not cause drowsiness or jitters, plus it is non-habit forming. NasalCrom is safe for kids ages two and up. The NasalCrom Difference Unlike most allergy medications, NasalCrom actually prevents nasal allergy symptoms from occurring in the first place.
