Which medication category is associated with hearing loss, tinnitus, and alterations in taste and smell?

• A. Diuretics
• B. Antibiotics
• C. Chemotherapeutic drugs
• D. Antihistamines

Answer: (A)

Drug-induced ototoxicity is a key consideration with loop diuretics. These medications can affect the inner ear’s hair cells and fluid balance, especially when given rapidly IV or in patients with kidney issues, leading to hearing loss and tinnitus. They can also cause changes in taste and smell due to electrolyte disturbances and neural effects in the gustatory system. In practice, if a patient on a loop diuretic reports new tinnitus, hearing changes, or an altered sense of taste, clinicians should reassess the dose, consider slower administration, monitor hearing, and adjust therapy as needed.
