What is an Ototoxic Medication

Ototoxic medications are drugs that can damage your inner ear, resulting in tinnitus1, or temporary or permanent hearing loss. If your hearing loss is diagnosed as sensorineural, it is important to consult with your doctor and Pharmacist on the medications that get prescribed to you, as these particular drugs have been known to aggravate an already existing hearing problem.

1Tinnitus is not a disease, but rather a condition. It is when you hear a sound in your ear, when there is no actual external noise. It is commonly noted as ringing in the ear(s).

How Much Hearing Can I Lose by Using Ototoxic Drugs

Just how much hearing loss occurs with ototoxic medications depends directly on how much of, and how long you use the drug. This grows significantly if you are using more than one ototoxic medication. In this situation, using more than one medication, can cause greater sensorineural hearing loss2 or worsen an existing hearing loss. It is good to know that with several of these drugs, like aspirin, hearing loss returns to normal after you stop taking it, no matter how long it has been used.

2Sensorineural hearing loss is the most common type of permanent hearing loss. It happens when damage to the inner ear (cochlea), or nerve routs to the inner ear or brain occurs. The damage cannot be medically or surgically repaired in most situations.

What Are the Symptoms of Ototoxicity

You should let your doctor know if you are experiencing any of the signs listed here:

  • dizziness
  • pressure in the ears
  • noises in the ears (tinnitus)
  • if a change or fluctuation in hearing loss occurs
  • if a greater loss in hearing is noticed

If you do happen to have the symptoms, talk to your doctor about it to find out if any of your prescribed medications are in fact ototoxic. It is also a good idea to consult with your pharmacist as to whether any over the counter (OTC) medications you take have ototoxic results. Your hearing specialist will also want to know the drugs you are taking, so he can determine the actual cause of changes in your hearing loss and perception.

Common Ototoxic Medications

Here you will find a list of medications and the effects they may have on your hearing loss.

Quinine

The effects found in drugs that have quinine in them—atabrine, legatrin, Q-Vel (muscle relaxer), aralen— are most closely related to those effects of aspirin. The effects usually go away once the medication is discontinued.

Loop Diuretics

This group usually only becomes ototoxic when given intravenously. This group will include the drugs, Edecrin, Lasix, and Bumex. Ototoxicity is very unusual when given as oral dosages.

Nonsteroidal Anti-Inflammatory Medications

When taking a dose of six to eight nonsteroidal Anti-Inflammatory pills—like Clinoril, Motrin, Advil— a day you may experience ototoxic effects. These toxic effects are generally reversible once you discontinue taking the drug.

Salicylates3

Products like aspirin, and drugs that have aspirin in them, can cause ototoxic effects after taking six to eight pills a day. In these cases, the toxic effects always go away after you stop taking the medication.

3Salicylate is used as an analgesic agent for the relief of mild to moderate pain. The most common and recognizable form is found as aspirin, which is used as an anti-inflammatory drug for soft-tissue and joint pain relief.

Antibiotics

The medications erythromycin, vancomycin, and streptomycin, are ototoxic when administered intravenously. If taken by mouth or in their topical form, they are not known to show any signs of hearing loss.

Chemotherapeutic Agents

The big hitters in this group are nitrogen mustard, vincristine, and cisplatin; which are all ototoxic when given for the treatment of cancers. The effects of these drugs is amplified when given in correlation with other ototoxic medications like aminoglycoside antibiotics—kanamycin, neomycin, gentamcin, tobramycin, etc.—and loop diuretics.
