Product Info

What is Posatex Otic Suspension?

Posatex Otic Suspension is an anti-bacterial, anti-inflammatory and anti-fungal medication for dogs that treats otitis externa associated with susceptible strains of yeast and bacteria. Posatex Otic Suspension requires a prescription from your veterinarian.


Dogs only


  • Antibacterial, anti-inflammatory and antifungal medication, treats otitis externa in dogs
  • Simple once-a-day dosing into the ear canal

How does Posatex Otic Suspension work?

Posatex Otic Suspension contains anti-bacterial, anti-inflammatory and anti-fungal properties to treat otitis externa, which is inflammation in the ear canal due to yeast and bacteria. Dogs with floppy ears tend to more susceptible to otitis externa since there is a limited amount of air-flow to the ear which creates a moist dark environment where bacteria and yeast thrive. Posatex Otic Suspension works by combining a broad spectrum antibiotic called Orbifloxacin, a potent anti-inflammatory agent called Mometasone Furoate Monohydrate and Novel triazole, a antifungal new to animal health.


Not for use in humans. Keep out of reach in children. Do not administer orally. Discontinue use if hearing loss is observed.

Customer Reviews
Posatex Otic Suspension is rated 4.8 out of 5 by 13.
Rated 4 out of 5 by from Works for our dog! This had been prescribed to our dog for an infection years ago and had used it when his ear would flare up now and then. Recently, we ran out and our vet no longer prescribed it so we tried their alternative but it didn't work so we were so pleased when we found it here!

Rated 5 out of 5 by from Problem Ears Dakota started shaking her head and ears because her ears were bothering her so much. At night she would wake me up shaking her head and ears. I tried everything over-the-counter with no success. I took her to the vet and they proscribed Posatex. Works very fast and now Dakota is happy and I am happy.

Rated 5 out of 5 by from best treatment thus far for my Springer's ears My vet prescribed this for my seven year old, ear infection-prone Springer Spaniel, and so far it seems to be working much better than any other treatment I've tried. The ver's price was actually lower - 28.00 - than the price listed here, which surprised me. application seems a little easier with the small bottle and elongated tip; I run warm water over it briefly before administering, so it won't be such an uncomfortable shock. We live in the NC mountains, without air conditioning, and the humid summers provide the perfect environment for infection; thankfully I am beginning to finally feel hopeful about keeping the problem at bay.

Rated 5 out of 5 by from I saw the difference after the first day! Now I know to get it from here to save quite a bit of money. My beagle is prone to getting ear infections because of his big floppy ears. The redness was already down after one day. I still haven't finished the entire dosage, but so far it's working great! Hoping he doesn't get it again for a long time. I'll be using the ear flush, the vet gave me, weekly to prevent the infections from coming back.

Rated 5 out of 5 by from Best Ear Cleaner For Long Eared Dogs I have seriously gone threw every ear suspension and cleaner known to man. I tried natural home remedies, all the over the counter, and prescription ones you can to deal with my dogs ear problems. The only medicine I have used that kills it with no problems and eliminates all the excess moisture in my pups ear is Posatex. I don't know what it is about solution, but it seriously has worked miracles on my dog (95lbs chocolate lab) and he's had the same problem 3 separate times. I wish you didn't need a prescription for it- it works so gooooood.

Rated 5 out of 5 by from Works wonders ! This medicine consistently aids in our battle with ongoing ear infections. Our English Springer is prone to infections and this seems to be the most effective remedy in additon to consistent cleaning and trimming her coat especially around her ears

Rated 5 out of 5 by from EXCELLENT EAR MEDICATION My dog has had a consistent ear infection in both ears for most of her life. No medication worked until my vet prescribed Posatex. Within a day her ears were no longer red and her head shaking stopped. My vet charged me $147.00 for this medication, and the next time I purchase it I will definitely order it from PetMeds. It has always been very difficult to administer ear medication to my dog but Posatex has such a soothing quality that she "allows" me to put it into her ears without any problems at all.
