I don't know who first gave out the prescription: whenever cats and dogs are abnormal, they will use gentamicin and recommend it to others everywhere.

Give everyone a popular science:

What does gentamicin mainly treat? Indications: bacterial infection. And many cats, dogs and the like are viral, which is not right at all!

And even if it is a gastrointestinal problem of bacterial infection, there are better drugs such as imipenem! !

Because gentamicin has strong toxic and side effects on internal organs and nerves of cats and dogs, it is mainly reflected in:

The toxic and side effects of 1 are: kidney, ureter, bladder toxicity-renal tubular changes (including acute renal failure and acute renal tubular necrosis), eye toxicity-visual field changes and bleeding. Peripheral neurotoxicity, pulmonary dyspnea. Hearing loss in ear canal. Abnormal development of hepatobiliary system.

Especially for bacterial gastroenteritis in cats and dogs, if gentamicin is used, the most likely situation is that the stomach is not good, but it will cause renal failure!
