Customer Question

We have a 10 year old boxer, she recently had surgery and was put on 500mg of apo cephalex, she was on this for almost 3 weeks 2xdaily, than she got an ear infection and was prescribed surolsn 2x daily. We realized that she was completely deaf after a few days of treatment, when we came home and not only didn't she hear us, but was startled when I touched her. We have taken her back to our vet, both her ears are clean other than some swelling in her right ear, we have to return to him this Friday unless we notice that her ear has become inflammed. Could this be a result of side effect to her meds?

Welcome to Justanswer! I am Dr. Altman and happy to assist you both today!

I am so sorry to hear about Ki, unfortunately this medication is ototoxic in some pets. Particularly if they have a ruptured ear drum but even without some dogs can have a reaction that results in deafness.

Here is one sites discussion:

What should I discuss my veterinarian before using Surolan Otic Suspension:
Tell your veterinarian if your pet has ever had an allergic reaction to this medication or any of the individual ingredients. Do not use in dogs with a perforated ear drum. Do not use with other drugs known to cause ear damage (ototoxicity).
What are the possible side effects of Surolan Otic Suspension:
Side effects that may occur include topical sensitivity and reduced hearing or deafness. Other side effects may also occur. Talk to your veterinarian about any side effect that seems unusual or bothersome to your pet.

I always caution my clients with these medications that if you note any changes to the hearing please discontinue the medication immediately and call for instructions. If the ear drum is not ruptured and she is having a reaction often they will have some hearing return but unfortunately how long it takes for this to occur can vary from a week to six months in the more rare cases.

I would talk to your vet about adjusting the ear medications to a straight steroid and antibiotic (typically I mix a baytril solution and dexamethasone per the dermatologist I work with) to help treat the inflammation and infection in the ear to hopefully help her return some hearing

I hope this makes sense and am sure this is not the information you were expecting. Please let me know how else I can assist you both tonight...
