Ear damage a known risk factor of antibiotic

- DR. KEITH ROACH Dr. Roach regrets that he is unable to answer individual letters, but will incorporat­e them in the column whenever possible. Readers may email questions to ToYourGood­Health@med. cornell.edu

Dear Dr. Roach: My wife had a laparotomy several months ago, and she lost the hearing in her right ear, possibly from an antibiotic given (intravenou­s vancomycin). She has had four steroid injections into the right ear, to no avail. She now has to be fitted with a hearing aid. What is the likelihood of her hearing ever coming back, and why did this happen?

S.W. Vancomycin is a commonly used antibiotic in hospitaliz­ed patients, and in some infections, it is the only choice for resistant organisms.

Vancomycin has several known side effects: It can cause people to become bright red during the intravenou­s infusion, and it can cause kidney disease, especially if the dose is too high, and especially if vancomycin is given with certain other antibiotic­s, such as streptomyc­in.

Damage to the ear is a known risk factor of vancomycin.

The ear damage is usually on both sides. Ear damage also is more likely at higher doses and is much more likely in older people. In one review, ear damage did not occur in people younger than 53, but 20% of people over 53 had measurable hearing loss. The cause seems to be damage to the nerve to the ear.

Most often, the damage is permanent. I can’t give you any percentage­s, as the best study I found did not include long-term follow-up.

Dear Dr. Roach: I am age 90. When I rise in the morning, I must sit on the edge of the bed for a minute or two to ease my dizziness. It takes an hour before it calms. Some of my golf pals have the same issue. Are there medicines or vitamins to reduce the dizziness?

W.J.G. What you are experienci­ng is called orthostati­c hypotensio­n, which just means the blood pressure goes down when you stand up.

Dizziness on standing is extremely common, but especially so as we get older. The body has numerous systems to allow blood to get up to our brains when we stand up, and these systems just get less sensitive over time.

The symptoms can be much worse in the presence of medication, especially some medication­s for high blood pressure, so reducing or changing medication­s — and possibly changing the time you take them — may help the symptoms.

Medication­s are a last resort for treating orthostati­c hypotensio­n. You are already following the most important advice I give, which is to sit for a while before trying to stand in the morning. Maintainin­g adequate fluid intake is important for everyone with this condition; salt may be necessary in people whose blood pressure can tolerate it.

Sleeping with the head of the bed raised by six inches may be helpful. Regular exercise, such as walking for 30-45 minutes three times a day, had great benefit in a small study.

Avoiding simple sugars and starches may also help. Compressio­n stockings are sometimes helpful. I don't know of any supplement­s that are effective.
