For mild swimmer’s ear, over-the-counter eardrops containing isopropyl alcohol or glycerin can help dry out the ear canal and clear the infection. If the infection is more than mild, you’ll likely need prescription antibiotic eardrops. A simple home remedy of equal parts white vinegar and rubbing alcohol can also work for early or very mild cases, though it shouldn’t be used if you have significant pain or suspect a damaged eardrum.
OTC Eardrops for Mild Cases
The most accessible option is over-the-counter eardrops designed to dry excess moisture from the ear canal. These typically contain isopropyl alcohol, which evaporates trapped water, or glycerin, which draws moisture out. You’ll find them at any pharmacy, often labeled specifically for swimmer’s ear. They work best when used at the very first sign of trouble: that waterlogged feeling, mild itchiness, or slight discomfort after swimming or showering.
These drops are a drying aid, not a powerful antimicrobial. If your ear is already swollen, draining fluid, or hurting enough to distract you, OTC drops alone probably won’t resolve the problem.
The Vinegar and Alcohol Home Remedy
A 50/50 mix of white vinegar and rubbing alcohol is a widely used home solution. The alcohol helps evaporate trapped water while the vinegar creates an acidic environment that discourages bacterial growth. Tilt your head, place a few drops into the affected ear, let them sit for about 30 seconds, then tilt your head the other way to drain.
Two important caveats. First, if the drops cause real pain, not just a brief sting, stop using them. Pain with an alcohol-based solution usually means the skin is already broken or significantly inflamed, and continuing will make things worse. Second, never use this mixture if you think your eardrum might be perforated. Signs of a perforated eardrum include sudden sharp pain followed by relief, fluid draining from the ear, or noticeable hearing loss.
Prescription Eardrops for Active Infections
When swimmer’s ear has progressed beyond mild irritation into a real infection, with notable pain, swelling, or discharge, prescription eardrops are the standard treatment. These combine an antibiotic to kill bacteria with a steroid to reduce the redness, itching, and swelling. The typical course is drops applied twice a day for seven days.
Your doctor diagnoses swimmer’s ear mainly through a physical exam. The hallmark sign is pain when they gently tug on your outer ear or press the small flap of cartilage in front of the ear canal. Pain level is the best indicator of how severe the infection is. You may also have visible swelling in the canal, redness, or discharge.
If the ear canal is very swollen, a doctor may place a small sponge-like wick into the canal so the drops can actually reach the infected tissue. This sounds uncomfortable, but it makes the medication far more effective when swelling has nearly closed off the canal.
Managing the Pain
Swimmer’s ear can hurt surprisingly intensely for such a small area of the body. While you’re waiting for the drops to work, over-the-counter pain relievers like ibuprofen or acetaminophen help take the edge off. Ibuprofen has the added benefit of reducing inflammation. Applying a warm (not hot) cloth against the outer ear can also provide temporary comfort.
Avoid the temptation to scratch inside the ear canal, even though itching is a common symptom. Scratching introduces more bacteria, damages the delicate skin lining the canal, and can turn a mild case into a severe one.
How Quickly Treatment Works
With appropriate treatment, most people notice improvement within one to three days. Pain typically eases within the first 24 hours. Uncomplicated cases clear up within about five days, though a full course of prescription drops usually runs seven days. Complete resolution, including any lingering fullness or reduced hearing, generally takes seven to ten days.
If your symptoms aren’t improving after two or three days of treatment, that’s worth a follow-up visit. The infection may need a different antibiotic, or there could be a fungal component rather than a purely bacterial one.
What Not to Put in Your Ear
Cotton swabs are the single biggest contributor to swimmer’s ear outside of actual swimming. They strip away the ear canal’s protective wax coating and create tiny scratches where bacteria thrive. Don’t use them to dry your ears, clean your ears, or scratch an itch. The same goes for anything else you might stick in the canal: pencils, paperclips, fingernails, or keys.
Certain eardrops also pose risks if your eardrum isn’t intact. Some older antibiotic drops containing neomycin have been linked to hearing loss when used with a perforated eardrum or ear tubes. Even some newer antibiotic drops may carry risks to the eardrum’s soft tissue. If you have ear tubes, a known perforation, or any history of eardrum problems, mention this before any drops are prescribed.
Preventing It From Coming Back
Swimmer’s ear tends to recur in people who swim regularly or live in humid climates. The CDC recommends a few straightforward habits to keep your ear canals dry:
- Drain water after swimming or showering. Tilt your head so each ear faces down. Pull your earlobe in different directions while tilted to help water escape.
- Dry your ears thoroughly. Use a towel, and if water still feels trapped, use a hair dryer on its lowest heat and fan setting, held several inches from the ear.
- Wear protection in the water. A bathing cap, earplugs, or custom-fitted swim molds all reduce how much water enters the canal.
- Leave your earwax alone. That waxy coating is your ear canal’s natural water repellent and antimicrobial barrier. Removing it makes infections more likely, not less.
Using a few drops of the vinegar-alcohol mixture after each swim is a common preventive strategy among frequent swimmers. It’s much easier to keep swimmer’s ear from starting than to treat it once the canal is inflamed and swollen.
