What is the main adverse effect of Lasix?

• A. Dehydration
• B. Hyperkalemia
• C. Hypokalemia
• D. Hypotension

Answer: (C)

Lasix, also known by its generic name furosemide, is a diuretic commonly used to treat conditions such as edema and hypertension. The main adverse effect associated with Lasix is hypokalemia, which is a condition characterized by low levels of potassium in the blood. This occurs because Lasix works by inhibiting the reabsorption of sodium and chloride in the kidneys, leading to increased urine production and a corresponding loss of electrolytes, including potassium. Potassium is essential for various bodily functions, including muscle contractions and heart rhythm. When Lasix causes excessive loss of potassium, it can lead to symptoms such as weakness, fatigue, muscle cramps, and in severe cases, arrhythmias. Therefore, monitoring potassium levels and the effects of Lasix on the body is crucial in patients taking this medication to prevent hypokalemia. In contrast, while dehydration, hyperkalemia, and hypotension can be side effects associated with diuretic use, they are not the most prominent or directly linked to the mechanism of Lasix. Dehydration can occur if excessive fluid loss happens, hyperkalemia is often seen when potassium-sparing diuretics are used, and hypotension can result from reduced blood volume due to diuresis
