Understanding Ototoxicity: How Medicines Affect Hearing

 

Ototoxicity refers to damage to the inner ear caused by specific medications. These drugs can harm the delicate sensory hair cells in the cochlea, leading to hearing loss and balance issues. Understanding ototoxicity helps in identifying and mitigating the risks associated with certain medications.

How Ototoxic Medications Damage the Inner Ear

 

Many medications target specific areas of the body but can inadvertently affect the inner ear, causing hearing loss, tinnitus, or balance disorders. More than 200 known ototoxic medications are on the market, including treatments for infections, cancer, and heart disease.

 

Ototoxic medications can:

 

• Damage hair cells: These cells convert sound waves into electrical signals.
• Disrupt nerve function: Medications can interfere with the auditory nerve.
• Affect balance organs: This leads to dizziness and vertigo.

 

Common Symptoms of Ototoxicity

 

Symptoms vary by damage severity and include:

 

• Hearing loss: Ranges from mild difficulty to severe impairment.
• Tinnitus: Persistent ringing or buzzing in the ears.
• Dizziness or vertigo: Sensation of spinning or imbalance.
• Fullness or pressure in the ears: Feeling of blockage.
• Effects can be temporary or permanent, depending on the medication, dosage, and individual sensitivity.

 

Let’s look closely at what medications can cause hearing problems in each specific medicine category. 

 

Antibiotics and Hearing Loss

 

While antibiotics combat infections, some can harm the inner ear.

 

Aminoglycosides: Notable for ototoxic effects, used for severe infections.

 

• Examples: Gentamicin, tobramycin, amikacin, kanamycin, streptomycin, and neomycin.
• Effects: Can cause permanent sensorineural hearing loss, dizziness, and tinnitus.
• Types: Vestibulotoxic (affecting balance) and cochleotoxic (affecting hearing).

 

Other antibiotics linked to hearing issues include:

 

Azithromycin (Zithromax)

Clarithromycin (Biaxin)

Vancomycin (Vancocin)

Minocycline (Minocin)

Ritonavir (Norvir)

 

Given the potential risks, it’s crucial to monitor hearing while using these antibiotics and consult your doctor if you experience any hearing changes.
