They don't really know WHAT it is that causes the hearing loss, because it only happens in certain individuals and it happens more often in geriatric dogs than it does in younger ones, although it has been known to happen in all ages.
The good thing about Otomax is that it's excellent for ear infections that involve Malassezia pachydermatis, which is a yeast that is difficult to control. It's really an excellent medication, and the hearing loss always resolves within about 30 days of stopping the use of it, so even if it does occur, it's nothing permanent.

LOL! Ghilly, I KNEW you'd have an answer on that one. :-)
I'm interested to hear about otomax causing temporary hearing loss. I wonder if it's the steroid component? My mom has had terrible recurring ear infections and refuses to use any ear drops now after a steroid-based one rendered her deaf in one ear for a week - after one use. With high blood pressure, she can't take any decongestants so ear drops and antibiotics are the only answer. Naturally, she NEVER does what the doctor tells her. :-\
Otomax contains corticosteroids, and as such should not be used in pregnant animals because it can cause a LOT of problems including cleft palate, deformities in the front legs, and other problems. I don't THINK there are any contraindications for use in NURSING females, but it would be best to consult your vet before using it just to be sure. One thing that I DO know about Otomax is that it has been known to cause temporary hearing loss in certain individuals, so be careful when using it that your pet doesn't get out of the house unnoticed, because if there is any appreciable hearing deficit, it could prove deadly, ie, if a car is coming your pet may not hear it and could get hit. Otomax is made by Schering-Plough Animal Health, so you can Google them and get a phone number for their Technical Services department. The vet there can tell you anything you need to know about Otomax.

Hello Katie, and welcome! I really can't answer your question, but in any case, your vet would be the best person to consult on that question. I suspect it's entirely safe, but one quick phone call and you'll know for certain. :-)
