Suffer from nasal allergies? We're all about allergy symptom prevention. 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. To enjoy the full preventative power of NasalCrom, it’s important to note that you should start using it a week or two before you expect to encounter problematic allergens. Fortunately, NasalCrom will still provide relief while it builds up full protection against further symptoms.
