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 it Works:

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.

What is the most important information I should know about Posatex Otic Suspension:

Posatex Otic Suspension is a prescription medication FDA approved for use in dogs only. It is available in a 15 gm plastic dropper bottle. Use this medication for the full amount of time prescribed by your veterinarian, even if your pet appears to be better. Symptoms may improve before the infection is completely healed. Shake well before use. The usual dose for dogs weighing less than 30 lbs is 4 drops into the ear canal daily. For dogs weighing 30 lbs or more, the dose is 8 drops into the ear canal daily. Therapy should continue for 7 consecutive days. Avoid getting this medication in your pet's eyes, nose or mouth.

Posatex Otic Suspension may be used for purposes other than those listed in this medication guide.

What should I discuss my veterinarian before using Posatex Otic Suspension:

Tell your veterinarian if your pet has ever had an allergic reaction to this medication or any of the individual ingredients or quinolones. Tell your veterinarian if your pet is pregnant or lactating.

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.

Rated 4 out of 5 by from My vet prescribed this for my cat. I used for the indicated amount of time and it cleared up the infection. HOWEVER, 2 WEEK LATER, it came back. Guess I need to search for a new vet since this medication is supposed to be used for dogs only!

Rated 5 out of 5 by from BEST EAR MEDICATION FOR DOGS My 5-year-old Shih Tzu has had ear infections since she was a little puppy. She has been on several ear medications, none of which worked on an ongoing basis. We have a new vet who prescribed Posatex and her ear infection has cleared up entirely. If you dog has a chronic ear infection ask your vet to prescribe this medication, you will not be sorry. The medication at my vet was going to cost $95 and I asked her to give me a prescription instead. This medication cost less than half at Pet Meds than what my vet was charging.

Rated 5 out of 5 by from works fast , THANK GOODNESS I have a redbone coonhound with long droopy ears, as long as I have had her (9 years) she has had infections. We have tried EVERYTHING!! Some things would work for a while then just as quickly stop working all together. She has had MANY MANY vet appointments, huge vet bills, surgical cleanings,her poor head wrapped like a mummy and nothing has worked for any significant time. Her ears can go from clean and perfect to red, swollen, bloody nightmares overnight. This medication was FINALLY prescribed to her last year. Now her infections are fewer and further between. Fingers crossed that she doesn't become immune.

Rated 5 out of 5 by from Best Ear Meds I've Ever Used My almost-17-year-old dog has had chronic ear infections for well over 10 years. My vet prescribed Posatex about 6 months ago, and I swear it's like a miracle medicine!! Nothing has every worked that quickly to give my pup relief. It's just amazing. SO glad I can order here on PetMeds!

Is there a way to get refillable prescriptions for dogs prone to ear infections rather than going to a vet every occurrence?

My dog is timely with his regular check ups and vaccinations. It gets really expensive to take him to the vet for an ear infection after every bath! Ear washes just don't do the trick. No vets will issue a recurring prescription because they want the money from the visit - something's got to give way! Can someone offer a suggestion or advice other than using a hair dryer - my dog is terrified of hair dryers and vaccuums.
Asked by: Lisa
I will ask my vet for a prescription for Posatex to keep in my medicine cabinet, so the next time she has an ear infection I will have it on hand. My vet charged me $147.00 for this medication, and as you can see, PetMeds has it for less than half the price. My dog goes to Banfield so I am not charged for her visits, just for the medications that are much cheaper at PetMeds.
