Correct Method for Cleaning Ears with Hydrogen Peroxide
After developing acute otitis media or suppurative otitis media, the ear often accumulates substantial purulent discharge. Therefore, the first step is to thoroughly cleanse the ear canal with hydrogen peroxide solution before initiating antimicrobial therapy.

How should hydrogen peroxide be correctly used for ear irrigation? First, “ear pre-soaking” is required: after instilling hydrogen peroxide into the ear, keep the affected ear tilted upward for several minutes—ideally at least two to three minutes—to allow adequate contact time. Subsequently, gently absorb the residual hydrogen peroxide and purulent discharge using a small, sterile cotton-tipped applicator (commonly available at maternity stores or supermarkets).

Only after completely drying the ear canal—removing all traces of both hydrogen peroxide and purulent discharge—should topical antibiotic ear drops be administered to treat the otitis media. Thus, two critical points must be observed when using hydrogen peroxide for ear cleansing: (1) ensure adequate pre-soaking time (at least 2–3 minutes), and (2) thoroughly dry the ear canal before applying subsequent ear drops.
