Questionmy older dog went deaf after using mometamax. is this reversible? how?
AnswerMometamax contains a very toxic antibiotic called gentamycin. That is most likely what is causing the problem. You need to let your vet know about this so that they can switch to a different type of antibiotic to treat the infection. In most cases of gentamycin ototoxicity, if you stop the medicine, the hearing will return within 2-3 weeks. The gentamycin has to diffuse out of the cochlear nerves in the inner ear and that can take a while.
