Furosemide can cause which adverse effect?

Furosemide can cause which adverse effect?

• A. Hypokalemia
• B. Hypocalcemia
• C. Hyperglycemia
• D. Ototoxicity

Answer: (D)

Furosemide, a loop diuretic, can be ototoxic, especially when given quickly by IV or at high doses. This means it can injure the structures of the inner ear, leading to tinnitus, dizziness, and potential hearing loss. The risk is higher if the patient already has hearing problems, is dehydrated, or is taking other ototoxic drugs like certain antibiotics. While furosemide can cause electrolyte disturbances such as low potassium or calcium, the adverse effect highlighted here is the classic ototoxic potential. If a patient reports ringing in the ears or a change in hearing, the infusion should be slowed or stopped and the clinician should assess the situation promptly.
