Everyone has heard that antibiotics "have a side effect." Some can go deaf.
More often hearing is impaired after aminoglycosides like gentamicin. In most cases, this depends on the amount of the drug in the blood.
Aminoglycosides spoil the place where the auditory nerve joins the sensory cells in our ear.
Sometimes after this hearing is restored, and sometimes not.
They say that there is also hereditary sensitivity to aminoglycosides. In European countries, about one in 500 people have this congenital trait.
Until now, we have not learned how to prevent this unpleasant side effect.
Aminoglycosides are very old antibiotics, but they still remain relevant. They cannot be replaced.
Equilibrium
If you remember, our inner ear contains not only hearing, but also a sense of balance. Some aminoglycosides damage the vestibular apparatus rather than hearing.
It turns out that a person will make noise in his ears, and even when walking, he can lose balance.
Ear drops
A separate story about ear drops with aminoglycosides. They still haven't figured out how harmful they can be. Hearing impairment after them happens, but it is believed that the inflamed mucous membrane of the middle ear itself will not allow a lot of antibiotic into the internal one.
Erythromycin with tetracyclines
In addition to aminoglycosides, erythromycin and tetracyclines can spoil hearing. If you noticed, then the name will not be able to determine the toxicity of the antibiotic. It's better to just know them.
So in the case of erythromycin with tetracyclines, you need to try very hard to get poisoned. But if a person is not all right with the kidneys, then this will be easier to do.
Azithromycin
Azithromycin, by the way, is also a relative of erythromycin. You can also go deaf from him.
It is important to know that azithromycin is excreted for a very long time. It will float in the blood for a week after the last capsule. Therefore, if a persistent person decides to continue, then the concentration of the drug will grow and grow and grow ...
