Is it Safe to Put Debrox in a Puppy's Ears?

New puppy owners want the best for their new family members, and while many human-grade products are safe to use on pets, it is critical to verify whether the active ingredient is appropriate to use for off-label purposes.

  1. History

    • Debrox, which has been available since 1958, is marketed as an ear wax removal solvent by GlaxoSmithKline. GSK acquired the product from Aventis Pharmaceuticals in 1993. Debrox is a foaming liquid applied to an adult ear in droplets, which softens ear wax buildup and aids in the removal process in a nonirritating, safe manner.

    Function

    • The active ingredient in Debrox is carbamide peroxide, which is created by combining hydrogen peroxide and urea. Carbamide peroxide is also known as urea peroxide, urea hydrogen peroxide, and percarbamide. When carbamide peroxide comes in contact with water, it releases oxygen. In Debrox, the release of oxygen is the source of the bubbles or foam when the liquid is applied to ear wax.

    Intended Users

    • According to the customer service at GlaxoSmithKline, Debrox is recommended for use in people age 12 and up. Because ear wax buildup is less likely to occur in children 12 and under, customers are advised to check with their physician prior to using the product in young children.

    Considerations

    • Debrox has not been tested for use in dogs or cats, and is not recommended for any off-label uses. GSK advises customers who want to use Debrox on a pet to contact their veterinarian.

    Expert Insight

    • Although specific tests of the effect of carbamide peroxide in pets are not readily availability, Newman Veterinary Medical Services warns that there is anecdotal evidence that carbamide peroxide can damage the ear tissue if used on animals. This potential for ototoxicity, or damage to the cochlea or auditory nerve, indicates that Debrox should not be used outside of its intended demographic-- people 12 years and older with ear wax buildup.
