We have a 18 mo. old heart transplant recipient. Also stage 2 chronic kidney disease. Last 3 days has had some brown/blackish tongue discoloration. Medications are Prograf, Cellcept, Iron supplement, milk of magnesia, and Bicitra. Last night and night before had slight temp. of between 99.0, and 100.4 lasting only 1-3 hours. Appetite decreased a little, but still active. Any thoughts?


With observation, elevated temp resolved without treatment. Tongue discoloration discovered to be due to ingestion of ink from a nontoxic crayola marker. Treated with a toothbrush. Appetite returned and no further symptoms. Sorry to bother you.
