Since their approval, topical calcineurin inhibitors have proven to be effective medications in the treatment of atopic eczema. On March 10, 2005, the Food and Drug Administration (FDA) followed the advice of the Pediatric Advisory Council and issued a "black box warning" for the use of Protopic (Tacrolimus) und Elidel (Pimecrolimus). This FDA alert has caused worldwide uncertainty among parents and patients. Several dermatological societies have issued critical position statements. This report reviews the existing information underlying the warning and places it into the context of current knowledge.
