Counterfeit Pet King Brands Zymox products were recently sold on Amazon, Pet King Brands officials reported. Amazon officials are notifying consumers about the counterfeit products, which were not manufactured by Pet King Brands nor supplied directly to Amazon by Pet King Brands.

As a precautionary measure, Pet King Brands officials recommend consumers who have purchased one of the Zymox Ear products directly from Amazon and not from one of the authorized sellers on Amazon to immediately discontinue use and contact Pet King Brands with any questions regarding these products or any other Zymox products purchased directly from the Amazon storefront.

Counterfeit products that have been identified so far as being sold by Amazon include: Zymox Otic Ear Solution with 1% Hydrocortisone, 1.25 fluid ounce, Zymox Otic Plus Ear Solution with 1% Hydrocortisone, 1.25 fluid ounce and Zymox Enzymatic Ear Solution with 0.5% Hydrocortisone, 1.25 fluid ounce.

Pet King Brands was able to detect the counterfeit products through its quality and safety enforcement program, officials said.

Everyday Pet King Brands fights the battle against counterfeiters, officials said, and has taken legal action to locate individuals around the world who are selling fake Zymox products that could harm pets.

“Our company will continue to fight counterfeiters who deceive consumers and sell products that risk the health or life of beloved pets,” said Pamela Bosco, founder and president of Pet King Bands in Westmont, Ill.

Pet King Brands is currently testing some of the counterfeit products that have been identified to determine their contents so they can offer the consumer more information.

Amazon has removed the listings that led to the sales of counterfeits and has issued refunds to customers who were sold and shipped the counterfeit products. However, there are many other unauthorized online sources that offer no guarantee consumers are receiving the authentic, USA-made products.

Consumers should only purchase Zymox or Oratene Brushless Dental Care products from Pet King Brands' Authorized Seller Brand Partners, officials. A list of Authorized Sellers is available at the “Where to Buy” page on

Authentic Zymox and Oratene products are also available through veterinary clinics and retailers nationwide.
