Gentamicin is an antibiotic of the aminoglycoside class. Betamethasone is a corticosteroid. The combination is used for the treatment of inflammation and bacterial infections of the ear. Products with clotrimazole are also effective against fungal (yeast) infections of the ear. A veterinary exam of the ear is necessary prior to use of this product in the ear. It should not be used in animals with a perforated eardrum.

Adverse reactions and toxicities are unlikely if used according to directions. If ingested, or given at high doses or for prolonged periods of time, side effects related to the triamcinolone may be seen. The most common effect is an increase in the amount of drinking and urinating. Less commonly you may see an increased appetite and weight gain, panting, diarrhea, vomiting, and behavior changes. Avoid contact with the eyes. Contact your veterinarian if your pet experiences a loss of hearing or balance while being treated with gentamicin. These effects are usually temporary. Do not use in animals who require their hearing to perform their work (military dogs, police dogs, seeing eye dogs, hearing dogs, etc.) as the hearing or vestibular (balance) impairment may not be reversible.
