A patient is described in whom vitamin B12 malabsorption was induced by the daily oral administration of 8 g of para-aminosalicylic acid. Para-aminosalicylic acid did not alter intestinal morphology, intestinal maltase, or sucrase activities, xylose excretion, or lead to steatorrhea. Thus, para-aminosalicylic acid should be added to the list of pharmacological agents that may induce a reversible malabsorption of vitamin B12.
