When it comes to the health and well-being of our beloved canine companions, navigating the world of medications can often feel like unraveling a complex puzzle. Among the myriad of treatments available, Posatex stands out as a go-to solution for combating ear infections in dogs.

However, determining the correct dosage can pose a significant challenge for pet owners and veterinarians alike.

In this guide, we delve into the intricacies of Posatex dosage for dogs, shedding light on the dosage guidelines, factors influencing dosage determination, and essential considerations for ensuring your furry friend receives the optimal treatment regimen.

Posatex is a medication specifically formulated for treating ear infections in dogs. It combines three active ingredients: orbifloxacin, mometasone furoate, and posaconazole. Orbifloxacin is an antibiotic that targets and eliminates the bacteria causing the infection, while mometasone furoate is a corticosteroid that helps reduce inflammation and itching in the affected ear.

Posaconazole is an antifungal agent that addresses any fungal elements contributing to the infection. Together, these components work synergistically to combat a wide range of bacterial and fungal pathogens commonly found in canine ear infections.

Posatex is available as an otic suspension, meaning it is applied directly into the ear canal for targeted treatment.

It is prescribed by veterinarians for the management of otitis externa, a common condition characterized by inflammation and infection of the external ear canal in dogs.

The correct dosage of Posatex for dogs to treat otitis externa is as follows:

  • For dogs weighing less than 13 kg (30 lbs), instill 4 drops per ear once daily for 7 days.
  • For dogs weighing 14 kg (31 lbs) or more, instill 8 drops per ear once daily into the ear canal.

4 drops of POSATEX® Otic Suspension contain approximately 1.0 mg of orbifloxacin, 0.1 mg of mometasone furoate monohydrate, and 0.1 mg of posaconazole, 8 drops would contain approximately 2.0 mg of orbifloxacin, 0.2 mg of mometasone furoate monohydrate, and 0.2 mg of posaconazole.
