The use of contrast media in patients who are taking Metformin can lead to lactic acidosis, a serious metabolic condition. Metformin is primarily cleared from the body through the kidneys, and the introduction of contrast media can potentially impair renal function, particularly in patients who are already at risk of kidney problems. This impairment can result in an accumulation of Metformin within the body, leading to increased lactic acid levels. When lactate levels rise significantly, it can overwhelm the body’s buffering systems, resulting in lactic acidosis, which is characterized by symptoms such as respiratory distress, abdominal discomfort, and decreased mental status.

The other conditions listed are not directly tied to the use of contrast media in Metformin users. For instance, hypertension and dehydration may occur due to various factors unrelated to the use of contrast, while hypoglycemia is more commonly associated with other diabetes medications rather than Metformin, especially in the presence of normal to high glucose levels. This highlights the specific risk associated with contrast media and Metformin, emphasizing the importance of renal monitoring when these two factors are involved.
