How does this medication 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, an antifungal new to animal health.

  • Best ear medicine for my Golden

    By on

    This works for my dogs but due to the packaging I never have a clue how much I am using. I transfer it to a clear bottle with an eye dropper so I know exactly how much I’m using. Good medication - others don’t work as well for mt ear infection prone Golden.

  • Works the best for my dog

    By on

    My long eared boy has an occasional ear issue, but he is so cranky when I try to drop anything in them. I've taken to using a disposable glove and putting a big blob on my finger and just gently putting it in that way! So much easier and the thick liquid doesn't make a mess! Posatex clears it up fast. And now that Chewy carries it I can save $$ too :)
