To the Editor. —  In his article "When the Urine Is Red," Berman fails to mention what, in my experience, is one of the most common causes of red-colored urine—the ingestion of any one of a number of laxatives containing danthron. Although this phenomenon is mentioned in the Physicians' Desk Reference, apparently not many physicians know of it, for I have seen a number of patients referred for evaluation of hematuria in whom only this danthron-induced discoloration of urine was present.
