Zymox Otic for Dogs

Zymox Otic enzymatic solutions treat external ear infections in dogs. You'll find the non-prescription ear drops in two formulas: Hydrocortisone or Non-hydrocortisone. The medication clears up bacterial and yeast infections in a dog's outer ear.

There are no known side effects with Zymox ear drops. Some pet owners do state it can be messy when their dog shakes his head following application, but it's easy enough to clean up. Just have a damp washcloth ready for a quick clean up.

Standard Ingredients in Zymox Otic Ear Drops

Zymox Otic ear drops contain three enzymes:

  • Lactoferrin

  • Lactoperoxidase

  • Lysozyme

Working together the enzymes develop antimicrobial properties to help fight bacteria and stop the development of yeast.

Lactoferrin is a protein that plays a key role in the immune system. It's a natural fungicide and bactericide. It's commonly found in the colostrum that comes before the breast milk and is the reason infants gain some of their mother's immunities. It works by preventing bacteria and fungi from being able to multiply.

Lactoperoxidase is an enzyme taken from the mammary and mucous glands, as well as saliva glands. Lactoperoxidase kills bacteria found in mucous membranes inside the ear.

Lysozyme destroy the outer walls of bacteria destroying the bacteria in the process. Lysozyme is found naturally in egg whites, tears, saliva and breast milk.

Hydrocortisone vs. Non-hydrocortisone Zymox Otic

The purpose of hydrocortisone in ear drops is to lessen inflammation. It's usually a safe glucocorticoid steroid, however it's not recommended in fungal infections or in animals with liver or kidney disease. Unless you know for certain that your dog doesn't have a fungal ear infection, it's best to avoid hydrocortisone.

Because hydrocortisone is anti-inflammatory, it is beneficial to dogs with very red, swollen ear tissue. It helps reduce the swelling and eliminates pain and itching.

Excessive use of hydrocortisone can lead to liver damage and behavioral changes. It can also cause weight gain and excessive thirst. It's unlikely that ear drops are going to affect your pet, but if you have any concerns over the use of steroids in your pet, you should opt for the non-hydrocortisone Zymox Otic ear drops.

Administering Zymox Otic Ear Drops

Never use Zymox ear drops if you've used any other ear medication or cleanser. There could be a reaction, but it's more common that the Zymox simply will fail to work.

When you use Zymox, apply enough of the solution to fill your dog's ear canal. Fold over the ear against the canal opening to prevent any of the solution from escaping if your dog starts shaking his head. Massage the lower ear to ensure the formula works its way down into the lower ear canal.

Once you've massaged the lower ear for a few minutes, release your pet and allow them to shake out any excess medication. Repeat this treatment daily for at least one week. Stubborn infections may require two full weeks of treatment before improvement is seen.
