Zymox Hydrocortisone Free Dog & Cat Ear Solution offers relief from the painful symptoms caused by ear infections in all animals including dogs, cats, reptiles, rabbits, ferrets and exotics of any age. The patented LP3 Enzyme System uses a powerful formula of enzymes to work against bacteria, fungus and yeast infections—you don’t even need to wash your pet’s ears beforehand. Plus, this formula doesn’t contain added hydrocortisone, so it can also be used if your pet is sensitive to hydrocortisone, including pregnant and lactating females.
