| contents | <p><span lang="EN-US">Furosemide is a commonly used loop diuretic for treating hypertension, heart failure, and edema. However, it can cause hypokalemia, especially in elderly patients with other health conditions. This case describes a 78-year-old female with type 2 diabetes mellitus, hypertension, and chronic obstructive pulmonary disease who was admitted with giddiness, tiredness, loose stools, altered sensorium, and leg swelling. After starting intravenous furosemide infusion (1 mg/hr) and stopping spironolactone, her potassium levels dropped significantly. She was diagnosed with acute gastroenteritis with severe dehydration, systemic hypertension, and furosemide-induced hypokalemia. The condition occurred due to increased potassium loss in urine caused by furosemide’s inhibition of the sodium-potassium-chloride transporter in the loop of Henle. Management included stopping the infusion, giving potassium chloride syrup (15 ml TDS), and reducing furosemide to 10 mg once daily. The patient’s potassium level and overall condition improved. The Naranjo scale score was 7, suggesting a probable relationship between furosemide and hypokalemia. This case highlights the need for careful monitoring of electrolytes and kidney function in elderly patients receiving loop diuretics to prevent serious complications. <span> </span></span></p> |
