Osurnia is formulated for dogs to help treat otitis externa—an infection of the ear canal better known as swimmer’s ears in humans. While there are many causes for otitis externa in dogs, Osurnia is designed to help your pal feel better. It applies like a liquid and stays like a gel, which penetrates deep. It's built to coat and adhere to the entire ear canal, increasing contact time at the infection site. Osurnia even works with your canine companion’s natural ear cleaning process and is gradually removed over time.


For the treatment of otitis externa in pets associated with susceptible strains of bacteria and yeast.

Possible Side Effects

Recommended Dosage

Osurnia should be administered in the clinic. Clean and dry the external ear canal before administering the initial dose of the product. Administer one dose (1 tube) per affected ear(s) and repeat administration in seven days. Do not clean the ear canal for 45 days after the initial administration to allow contact of the gel with the ear canal. Cleaning the ear may affect product effectiveness. If alternative otic therapies are required, it is recommended to clean the ear(s) before application. Open tube by twisting the soft tip. Insert the flexible tip into the affected external ear canal(s) and squeeze entire tube contents into the external ear canal(s). After application, gently massage the base of the ear to allow the gel to penetrate to the lower part of the ear canal.

Storage Instructions

Osurnia should be refrigerated at temperatures between 36° - 46°F. For application comfort, it may be brought to room temperature. Osurnia may be refrigerated for up to 3 months.


What causes otitis externa in dogs?

Otitis externa is inflammation of the outer ear. Sometimes otitis externa in dogs is caused by allergies. In other cases, otitis externa can be the result of bacteria and/or yeast in the ear. Ear mites, growing hair, trapped water or a foreign body inside the ear can all influence how likely a dog is to get otitis externa. Frequent bathing, swimming and incorrect cleaning methods can also contribute to the infection.

The signs to look for include:

  • Foul-smelling ears
  • Ear scratching and/or head shaking
  • Discharge from the ear
  • Crusted or scabby skin under the ear flap
  • Swelling or redness around the ear
  • Reluctance to have head touched
