What is Posatex for Dogs Used For? A Comprehensive Guide

Posatex is a medication that is specifically formulated for dogs to treat certain ear infections. It is a combination of three active ingredients: orbifloxacin, mometasone furoate, and posaconazole. Each of these ingredients plays a crucial role in effectively treating various types of ear infections in dogs.

1. Orbifloxacin

Orbifloxacin is a fluoroquinolone antibiotic that helps eliminate bacteria causing the infection. It works by inhibiting the growth and reproduction of bacteria, ultimately eradicating the infection from the dog’s ear. This ingredient is particularly effective against common bacteria such as Staphylococcus spp., Streptococcus spp., and Pseudomonas spp.

2. Mometasone Furoate

Mometasone furoate is a corticosteroid that helps reduce inflammation and itching in the dog’s ear. It works by suppressing the immune response, thereby alleviating discomfort and promoting healing. This ingredient is especially beneficial for dogs experiencing allergic reactions or inflammation due to the ear infection.

3. Posaconazole

Posaconazole is an antifungal agent that targets and eliminates fungal infections in the dog’s ear. It effectively combats common fungi such as Malassezia pachydermatis, which is a frequent cause of ear infections in dogs. Posaconazole helps restore the balance of microorganisms in the ear, preventing further infections.

When is Posatex Prescribed?

Posatex is typically prescribed by veterinarians to treat otitis externa, which is an inflammation or infection of the external ear canal in dogs. This condition can be caused by various factors, including bacteria, yeast, or fungi. The combination of orbifloxacin, mometasone furoate, and posaconazole in Posatex provides a comprehensive treatment approach for these infections.

How to Use Posatex

Before administering Posatex to your dog, it is crucial to thoroughly clean the affected ear canal. This helps remove debris and excess earwax, allowing the medication to penetrate effectively. Follow your veterinarian’s instructions on the dosage and frequency of application. Typically, Posatex is administered by gently squeezing the prescribed amount of medication into the ear canal and massaging the base of the ear to distribute it evenly.

Possible Side Effects

While Posatex is generally safe for dogs when used as directed, some side effects may occur. These can include increased thirst, increased urination, vomiting, diarrhea, and ear irritation. If you notice any unusual or severe side effects, contact your veterinarian immediately.


Posatex is a valuable medication for treating ear infections in dogs.
