Osurnia is an antibacterial, antifungal, and anti-inflammatory otic gel meant for the treatment of otitis externa (ear infection) in dogs. This solution quickly treats ear infections with just two doses per ear, given one week apart. After using Osurnia on your dog, you don't have to clean the ears for 45 days. The alcohol-free gel formulation comes in a soft flexible tip that is gentle on dog's ears. Osurnia is available in a 2 x 1 ml and 20 x 1 ml carton of premeasured single-dose tubes and requires a prescription from your veterinarian. Osurnia requires refrigeration. To ensure proper temperature, it requires overnight shipping at an additional cost.
