• Barium meals are also administered in Robert Littel's book The Company, and later in the TV short-series with same name.

• In A Clash of Kings, the second book in the A Song of Ice and Fire series, Tyrion Lannister uses the trap to find out which member of the King's Privy Council is reporting to his sister, the Queen Regent Cersei Lannister. To the Grand Maester Pycelle, he tells of a plot to marry his niece, Princess Myrcella, to Prince Trystane of the powerful House Martell, from Dorne. To Littlefinger, he claims he will instead send Myrcella to be raised by Lysa Arryn and married to her son Robert. To Varys, he says his plan is to send his nephew Tommen to the Martells. When Cersei confronts him, and knows only of the plan to send Myrcella to Dorne, Tyrion knows Pycelle to be the leak.
