What is the recommended over-the-counter treatment for cerumenosis?

Carbamide peroxide is considered the recommended over-the-counter treatment for cerumenosis, primarily because it acts as both a softening agent and a cleansing agent for earwax. When applied, it releases oxygen, which helps to break down and emulsify the earwax, facilitating its removal from the ear canal. This makes it particularly effective in managing excessive earwax buildup, thus alleviating symptoms such as hearing loss or discomfort that can be caused by cerumen impaction.

Other options may serve different roles in ear care but do not match the specific effectiveness of carbamide peroxide in treating cerumenosis. Acetic acid drops are primarily used for managing infections in the ear canal rather than for wax buildup. Hydrogen peroxide can be irritating and is less favored due to its potential for causing discomfort or damaging sensitive tissues in the ear. Mineral oil, while it can help to soften earwax, lacks the effervescent action that carbamide peroxide provides, which is key for effective cerumen removal.

Thus, carbamide peroxide stands out as the most effective over-the-counter treatment for cerumenosis, given its dual action of softening and clearing earwax while being safe for use in the ear.
