From the manufacturer's website:
Excessive earwax buildup is a common problem that can lead to ear discomfort, itchy ears or partial loss of hearing. Debrox® is a safe, gentle, and non-irritating way to remove earwax build-up in the privacy of your own home.
Debrox® safely removes excessive earwax through the power of microfoam cleansing action. When drops are placed in the ear, oxygen is released. This release allows Debrox® to foam on contact as it gently softens and loosens earwax. The sustained microfoam cleansing action of Debrox® may make mild bubbling or crackling sounds. This is not cause for alarm and is evidence of Debrox® hard at work inside your ear. Once broken down, earwax is able to naturally drain from the ear. Ears are relieved of built-up earwax, dirt, and other debris so you can return back to daily life without muffled hearing.
The Debrox® Earwax Removal kit includes Debrox® Drops and a soft rubber bulb ear syringe. It is gentle enough for children ages 12 and up, yet strong enough for an adult.
