Metformin-induced lactic acidosis and acute pancreatitis precipitated by diuretic, celecoxib, and candesartan-associated acute kidney dysfunction.
Polypharmacy may lead to synergistic complications from the different medications. We report the case of a 50-year-old woman who was prescribed 11 drugs, including a diuretic, celecoxib, metformin, and candesartan, and who developed acute kidney dysfunction while on these drugs, manifesting as severe proteinuria, acute azotemia, hyperkalemia. The kidney injury caused the accumulation of metformin, leading to lactic acidosis and acute pancreatitis. Sodium bicarbonate hemodialysis not only improved the metabolic abnormalities but also hastened the removal of metformin.
