Dear Ceebee: I ck'd my med bks & drug guide. Nothing stated prednisone had anything to do w/WBC count increasing. Asthma causes inflammation of the airways and inturn, WBCs rally to fight the infection. That may be a reason you have increased WBC count. It further stated that sometimes prednisone will mask other infections that are not related to asthma as it is a corticosteroid and fights inflammation. Did your MD go over your lab results w/you?
