Indications for Use
Treatment of minor cuts, scratches, hot spots, or inflammation due to contact dermatitis or allergies.

General Information
FDA approved for use in dogs and/or cats to treat skin and/or ear infections or inflammation. Available by prescription and over the counter. The antibiotic helps clear the infection while the steroid component helps decrease the itching which helps keep the pet from licking or scratching the area and prolonging the problem. Skin infections/abrasions heal faster if kept clean and dry and the pet is not allowed to lick. Should see an improvement within 48-72 hours of starting the medication.

Usual Dose and Administration
Applied liberally to the skin/ear 2-3 times a day for about a week while the infection is healing. Keep the pet from licking the area for at least 15 minutes to allow the products to soak into the skin and take effect.

Side Effects
Rare when used according to the directions. May see skin irritation or redness.

Do not use in patients hypersensitive (allergic) to the ingredients.

Do not allow the pet to lick the injury as it delays healing.

Not for use in cases of deep or serious injury. Contact your veterinarian if the problem is not cured in a week or if it worsens.

If medication comes in contact with pet's eyes, flush eyes thoroughly and contact your veterinarian.

Drug or Food Interactions
Unlikely. Do not use different medications together without consulting your veterinarian. No known food interactions.

Unlikely unless the pet eats the container and contents.

Keep this and all other medications out of the reach of children and pets.
