Vitamin D Improves the Treatment of Allergic Rhinitis



A recent study conducted at the University of Chicago concluded that Vitamin D supplement boosts up the treatment of allergic rhinitis with Fluticasone ( Flonase, Veramyst)  nasal spray.  


It was a 2 weeks, placebo controlled study. All patients received daily Fluticasone 100 mcg a day into each nostril. In addition, patients were randomized to receive daily oral vitamin D 4,000 IU or a placebo. 


At baseline the average vitamin D level was 30 ng/ml. By the end of the 2 weeks, it rose to an average of 37 ng/ml in vitamin D treated patients. In the placebo group, vitamin D level did not change from baseline. 


Vitamin D cut down symptom score by 6.9 points compared to 3.7 points for placebo group. The effect was apparent by Day 2 and remained significant throughout the study period. The investigators were shocked at the results. 


The study was presented at the 2012 Annual meeting of the American Academy of Allergy, Asthma and Immunology.
