Exceeding the maximum Lasix dose significantly increases the risk of serious complications. Your kidneys may suffer from dehydration and electrolyte imbalances, leading to kidney failure. This can manifest as decreased urine output, fatigue, nausea, and muscle weakness.
Severe dehydration is another major concern. This can cause low blood pressure (hypotension), dizziness, and fainting. In extreme cases, dehydration can be life-threatening.
Electrolyte disturbances, particularly low potassium (hypokalemia), are common with high Lasix doses. Hypokalemia weakens the heart and increases the risk of irregular heartbeats (arrhythmias), potentially fatal. Symptoms include muscle cramps, fatigue, and weakness.
Hearing loss is a possibility, especially with prolonged high doses. This is due to the diuretic’s impact on the inner ear. The hearing loss may be temporary or permanent.
Always follow your doctor’s prescribed dosage. Never increase your dose without consulting them. Report any unusual symptoms immediately, particularly those listed above. Your health is paramount; responsible medication use is crucial.
