Quick answerOver-the-counter swimmer's ear drops, such as Debrox Swimmer's Ear and Swim-EAR, are ear drying aids: isopropyl alcohol 95% in an anhydrous glycerin 5% base that dries water in the ears after swimming, showering or bathing. They prevent problems from trapped water; they do not treat an infection. The CDC says swimmer's ear itself is a bacterial infection that can be treated with antibiotic ear drops from a healthcare provider, and that you should avoid drying drops if you have ear tubes, a punctured eardrum, swimmer's ear or ear drainage. Check with your provider if you have ear pain or drainage.

What swimmer's ear is

The CDC describes swimmer's ear (acute otitis externa) as a bacterial infection usually caused by water that stays in the outer ear canal and wears down protective wax and skin. It is most often seen in children, but anyone can get it, and it is not contagious.

Symptoms the CDC lists include pain when the outer ear is tugged or pressed near the small flap in front of the ear canal, itchiness inside the ear, drainage from the ear, and redness and swelling.

Swim-EAR ear drying aidIsopropyl alcohol 95%, anhydrous glycerin 5% base4 to 5 drops in each affected ear

Details are from each product's DailyMed label. Both list the purpose as an ear drying aid that dries water in the ears and relieves water-clogged ears after swimming, showering, bathing or washing the hair.

When not to use drying drops

Both labels say to ask a doctor before use if you have ear drainage or discharge, ear pain, irritation or rash in the ear, dizziness, or have had ear surgery. Stop use and ask a doctor if irritation (too much burning) or pain occurs.

The CDC adds that you should ask your healthcare provider before using ear-drying drops and avoid them if you have ear tubes, a punctured eardrum, swimmer's ear or ear drainage. Other label warnings: the drops are flammable, so keep them away from fire or flame; do not use in the eyes; and keep out of reach of children.

CDC tips to keep ears dry

How to use swimmer's ear drops

For wax buildup, which is a separate problem, see our ear wax removal kit guide and ask a doctor first if you have ear pain.

When to see a doctor

The CDC says to check with your healthcare provider if you have ear pain or drainage, and that swimmer's ear can be treated with antibiotic ear drops. Drying drops are not a substitute for that treatment. Do not keep using drying drops on an ear that hurts, itches or drains, since the labels and the CDC both say to check with a provider first. See a provider promptly for ear pain, swelling, drainage, fever, or hearing changes, and for any child with ear pain after swimming.
