Patient Basics: Earwax Blockage (Wax Blockage of the Ear Canal)

An earwax blockage happens when wax builds up and plugs the ear canal. It can muffle hearing or make the ear feel full. Earwax itself is normal, because it cleans and protects the canal and usually works its way out without help. A blockage is easy to treat, and the safest first step is softening drops, not cotton swabs.

Key points

• Earwax (cerumen) traps dust and germs and keeps the skin of the ear canal from drying out. Most ears never need cleaning inside.
• Cotton swabs, earplugs, earbuds and hearing aids can push wax deeper and cause a blockage.
• Signs of a blockage include muffled hearing, a plugged feeling, ringing, itching or a mild earache.
• Drugstore ear drops often soften the wax enough for it to come out. A doctor can wash out or remove wax that won’t clear.
• Don’t try to clean your ear if it hurts and you have a fever or drainage, or if you have a hole in your eardrum. See a doctor instead.

What causes earwax blockage

Small glands near the opening of the ear canal make wax. When you chew and talk, your jaw moves, and this slowly pushes old wax and dead skin toward the opening. There it dries and falls out. This self-cleaning works well for most people.

A blockage (impaction) forms when wax collects faster than it can leave, or gets pushed back toward the eardrum. Common reasons include:

• Cotton swabs, fingers or other objects that pack the wax down
• Hearing aids, earplugs and earbuds that block the opening
• Narrow, curved or hairy ear canals
• Older age, when wax tends to get drier and harder
• Skin conditions, such as eczema, that cause flaking in the canal

Some people also make more wax than others.

Symptoms

• Muffled hearing, often in one ear
• A feeling of fullness, as if the ear is plugged
• Ringing or buzzing (tinnitus)
• Itching or a mild ache
• Dizziness
• A tickly cough, because a nerve in the ear canal is linked to the throat
• Whistling from a hearing aid

Strong pain, fever, fluid coming out or sudden hearing loss point to other problems, such as an infection, and need a doctor’s check.

How it’s diagnosed

A doctor or nurse looks into the ear with a small lighted scope (an otoscope). Wax that hides the eardrum or causes symptoms counts as a blockage. If your hearing doesn’t come back after the wax is out, you may need a hearing test.

How earwax blockage is treated

At home

Softening drops are the first step for most people. Options include:

• Drugstore ear drops that contain carbamide peroxide
• Mineral oil, baby oil or glycerin
• Saline (salt water)

Lie on your side, put a few drops in the ear and stay still for several minutes so they soak in. Repeat once or twice a day for a few days. The wax may then drain out on its own.

Some people then rinse the ear gently with a rubber bulb syringe and water at body temperature. Cold or hot water can make you dizzy. Don’t rinse if you’ve had ear surgery, have ear tubes or have a hole in your eardrum. If you have diabetes or a weak immune system, ask a doctor first, because rinsing can lead to a serious infection of the ear canal.

At the doctor’s office

• Rinsing (irrigation). Warm water is flushed into the canal with a syringe or a special device to wash out the wax.
• Removal with tools. The doctor uses a tiny loop or spoon (curette) or gentle suction while looking into the ear. Ear, nose and throat doctors often use a microscope for this.

Removal is usually quick. The ear may feel a little sore afterward, and some people feel dizzy for a short time. Rarely, removal scratches the canal, causes an infection or makes a hole in the eardrum.

What to avoid

• Cotton swabs, hairpins, keys or anything else pushed into the canal
• Ear candles. They don’t pull wax out, and the FDA has warned that they can burn the face and ear.
• Water jet devices made for cleaning teeth
• Scoops and camera tools sold online, unless your doctor says they’re safe for you

Lowering your risk

• Clean only the outer ear, using a washcloth.
• Keep cotton swabs out of the ear canal.
• If you wear hearing aids or often get blockages, ask your doctor about using softening drops now and then.
• Have your ears checked at regular visits if you wear hearing aids.

When to see a doctor

• Drops haven’t helped after 3 to 5 days
• You have ear pain, fever, fluid draining or bleeding from the ear
• You feel dizzy and it doesn’t pass
• You’ve had ear surgery, ear tubes or a hole in the eardrum

Get care within a day or two for sudden hearing loss in one ear. If wax isn’t the cause, it may be a problem with the hearing nerve, and treatment works best when it starts early.

Common questions about earwax blockage

Can earwax blockage cause dizziness or ringing in the ears?

Yes. A plug of wax near the eardrum can cause ringing (tinnitus), a full feeling and sometimes dizziness or a tickly cough. These symptoms usually go away once the wax is out. If they don’t, see a doctor, because something else may be causing them.

How long do ear drops take to clear earwax?

Most wax softens after 3 to 5 days of drops used once or twice a day. Some of it drains out on its own, and the rest may need a gentle rinse or removal by a doctor. If your hearing isn’t better after about 5 days, make an appointment.

Is it safe to put hydrogen peroxide in my ear?

Drugstore drops made with carbamide peroxide are safe for most adults whose eardrum is intact. Plain hydrogen peroxide also loosens wax, but it can sting or irritate the skin of the canal. Don’t put any drops in an ear with a hole in the eardrum, ear tubes or fluid draining out.

Questions to ask your doctor

• Is wax causing my symptoms?
• Which drops should I use, and for how long?
• Is it safe for me to rinse my ears at home?
• How often should my ears be checked?
• Do I need a hearing test?
