Most ear infections clear up on their own within two to three days without antibiotics. The right treatment depends on where the infection is: middle ear infections (behind the eardrum) often resolve with pain management and time, while outer ear infections (in the ear canal) always require antibiotic ear drops. Knowing which type you’re dealing with is the first step toward getting rid of it.
Middle Ear vs. Outer Ear Infections
Middle ear infections happen when bacteria or viruses travel up the narrow tube connecting your throat to your middle ear, usually during or after a cold. Children get these more often because their tubes are shorter and more easily blocked. You’ll feel pressure and pain deep inside the ear, and hearing may be muffled.
Outer ear infections, often called swimmer’s ear, start in the ear canal itself. They’re typically caused by water sitting in the canal after swimming or bathing, creating a warm, moist environment where bacteria thrive. The telltale sign is pain that gets worse when you tug on your earlobe or press on the small flap of cartilage in front of the ear canal. You may also notice itching, redness, or discharge.
This distinction matters because the treatments are completely different. A middle ear infection may not need medication at all. An outer ear infection won’t heal without prescription ear drops.
When Antibiotics Are Needed
Your body’s immune system can fight off many middle ear infections without help. Both bacteria and viruses cause these infections, and antibiotics do nothing against viruses. That’s why doctors often recommend waiting 48 to 72 hours before prescribing antibiotics for middle ear infections, a strategy called watchful waiting.
Antibiotics are prescribed right away in certain situations:
- Fluid draining from the ear. This signals a more advanced infection.
- Severe symptoms. A fever of 102.2°F (39°C) or higher, intense pain lasting more than 48 hours, or a child who looks very unwell.
- Babies under six months. Their immune systems aren’t mature enough to reliably clear the infection.
- Both ears infected in children under two. Bilateral infections in young children carry higher complication risk.
For older children and adults with a single infected ear and mild symptoms, waiting and managing pain is a reasonable first approach. If things aren’t improving after two days, a follow-up visit is warranted.
Treating Swimmer’s Ear
Outer ear infections always need antibiotic ear drops. These prescription drops typically combine an antibiotic with a steroid that reduces swelling and pain in the canal. Cure rates with these drops run between 87% and 97%.
To use ear drops effectively, lie on your side with the affected ear facing up. Clean the outer ear gently with a warm, damp washcloth first. For adults, pull the top of the ear up and back to straighten the canal before putting drops in. For children, pull the ear down and back instead, since their ear canals are shorter and angled differently. After the drops go in, gently press the small cartilage flap in front of the ear canal to help the medication travel deeper. Stay lying on your side for a few minutes so the drops don’t run out.
Avoid swimming for at least a week while the infection heals. Oral antibiotics are only used for severe cases that don’t respond to drops.
Managing Pain at Home
Whether or not you need antibiotics, pain relief is a priority. Over-the-counter ibuprofen and acetaminophen are the go-to options. Ibuprofen is especially useful because it reduces both pain and inflammation, but it shouldn’t be given to babies under six months.
For children, dosing is based on weight, not age. The packaging on children’s liquid ibuprofen or chewable tablets includes weight-based charts. Always use the measuring device that comes with the product rather than a kitchen spoon.
Warm and cold compresses can also help. Place a warm (not hot) cloth over the affected ear for comfort, and try alternating between warm and cool compresses every 30 minutes. This won’t cure the infection, but it can take the edge off while you wait for it to resolve or for medication to kick in.
What to Avoid
Ear candling, a practice that involves placing a lit, hollow cone of fabric into the ear canal, does not remove wax or treat infections. It can burn the ear canal, rupture the eardrum, and actually push wax deeper into the ear. No credible research supports its use.
Don’t put anything inside the ear canal on your own, including cotton swabs, hydrogen peroxide, or home remedy drops, unless directed by a healthcare provider. Poking around in an inflamed ear canal risks making the infection worse or damaging the eardrum.
Signs of a Serious Complication
Most ear infections are uncomfortable but harmless. Rarely, an untreated middle ear infection spreads to the bone behind the ear, a condition called mastoiditis. Before vaccines and antibiotics, this was a leading cause of death in young children. It’s now rare, but still worth recognizing.
Warning signs include swelling or redness behind the ear, the ear visibly sticking out more than the other side, pus draining from the ear, worsening hearing loss, high fever, dizziness, or confusion. In young children (two and under), look for persistent fussiness, pulling at the ear, or unusual lethargy. Left untreated, mastoiditis can lead to hearing loss, facial paralysis, or infections that spread to the brain.
Preventing Repeat Infections
Some children get ear infections repeatedly, especially between ages six months and two years. Keeping up with the standard childhood vaccination schedule helps, since vaccines against common bacteria reduce the pool of infections that can trigger ear problems. Breastfeeding, avoiding secondhand smoke, and keeping kids away from large group childcare settings during cold season also lower risk.
For swimmer’s ear, the best prevention is keeping your ear canals dry. Tilt your head to each side after swimming to drain water, and consider using a towel or hair dryer on a low, cool setting. Over-the-counter drying drops (a simple alcohol and vinegar solution) used after swimming can help evaporate trapped moisture before bacteria have a chance to grow.
