What is the mnemonic for remembering the contraindications for metformin?

• A. K - Kidney disease
• B. A - Alcoholism
• C. C - Contrast media exposure
• D. B - Bladder cancer

Answer: (A)

The correct choice is associated with the contraindications for metformin, specifically related to kidney function. Metformin is primarily eliminated through the kidneys, and any impairment can increase the risk of lactic acidosis, a serious side effect associated with metformin use. This makes significant renal impairment a critical contraindication for the drug. The other options, while also related to conditions that could complicate the use of metformin, are not as primary or well-known as the risk associated with kidney disease. For instance, alcoholism can impact metabolism and increase the risk of lactic acidosis, and recent exposure to contrast media can pose risks due to potential renal function changes. Bladder cancer is considered in some situations, but it is not a direct contraindication as kidney disease is. Thus, the mnemonic emphasizing kidney disease encapsulates the most vital aspect of metformin contraindications, making it the correct choice in this context.
