Prescription Osurnia Otic Gel for Dogs

What is Osurnia?

Osurnia Otic Gel is a prescription treatment for canine ear infections (otitis externa). It contains three active ingredients—florfenicol (antibiotic), terbinafine (antifungal), and betamethasone acetate (anti-inflammatory)—in a gel that coats the ear canal and provides continuous relief. The gel adheres to the ear lining, staying in place to deliver medication over time, working with your dog’s natural ear-cleaning process. Only two applications are needed, one week apart.

What is Osurnia used for?

Osurnia treats otitis externa caused by susceptible strains of Staphylococcus pseudintermedius (bacteria) and Malassezia pachydermatis (yeast). These infections commonly cause ear inflammation, discharge, itching, and discomfort in dogs.

What is Otitis Externa in Dogs?

Otitis externa is an infection or inflammation of the outer ear canal. It’s a common condition in dogs, especially those with floppy ears. Causes may include bacteria, yeast, moisture, allergies, ear mites, foreign objects, or underlying skin issues.

Common Symptoms of Otitis Externa:

Scratching or pawing at ears
Head shaking or tilting
Red, swollen, or painful ears
Foul-smelling ear discharge
Crusting or scabbing around the ears
Hearing loss or balance problems (in severe cases)
