Most adult ear infections improve within a few days of starting treatment, and the right approach depends on whether the infection is in your outer ear canal or behind your eardrum in the middle ear. These two types have different causes, different symptoms, and different treatments. Outer ear infections are treated with prescription ear drops, while middle ear infections typically require oral antibiotics.
Outer Ear vs. Middle Ear Infections
Your outer ear canal is about 2.5 centimeters of skin-lined tube running from the visible part of your ear to your eardrum. When this canal gets infected, usually from trapped moisture or minor skin damage, bacteria that normally live on your skin overgrow and cause what’s known as otitis externa, or swimmer’s ear. The hallmark symptoms are itching that progresses to increasing pain, a red and swollen canal, and sometimes pus or flaky debris. Pain typically gets worse when you tug on your earlobe or press on the small flap of cartilage in front of your ear canal.
A middle ear infection (otitis media) sits behind the eardrum, in a space connected to the back of your throat through a narrow tube called the eustachian tube. When that tube swells shut from a cold, allergies, or sinus congestion, fluid gets trapped and bacteria multiply. You’ll notice deep ear pain, muffled hearing, and sometimes a feeling of fullness or pressure. Middle ear infections in adults are less common than in children, but the bacteria involved and the treatment approach are similar.
Treating an Outer Ear Infection
Outer ear infections are treated with prescription ear drops that combine an antibiotic with a steroid to fight the infection and reduce swelling at the same time. A typical regimen is 4 drops into the affected ear twice a day for 7 days. Your doctor may also gently clean the canal first to help the drops reach the infected tissue.
To get the most out of your drops, lie down with the affected ear facing the ceiling. Gently pull your earlobe up and back to straighten the canal, then squeeze in the correct number of drops. Stay still for about 5 minutes, then press lightly on the small flap of cartilage at the front of your ear to pump the drops deeper. Wipe away anything that spills onto your skin. Don’t let the dropper tip touch your ear or any other surface.
While the drops are working, keep the ear dry. Avoid swimming, and use a cotton ball lightly coated with petroleum jelly when showering. Resist the urge to scratch or insert anything into the canal, including cotton swabs.
Treating a Middle Ear Infection
Middle ear infections in adults are typically treated with oral antibiotics. The standard first-line choice is amoxicillin-clavulanate, taken twice daily. For mild to moderate infections, a course of 5 to 7 days is usually sufficient. More severe infections, those with significant hearing loss, intense pain, or a very red eardrum, are generally treated for 10 days.
Higher-dose antibiotics may be needed if you’ve used antibiotics within the past month, are over 65, have a weakened immune system, or live in an area with high rates of antibiotic-resistant bacteria. Your doctor will make that call based on your situation. Finish the entire course even if you start feeling better after a day or two, since stopping early increases the chance of the infection returning or becoming resistant to treatment.
Managing Pain at Home
Regardless of the type of infection, ear pain can be significant. Ibuprofen at 400 mg every four to six hours as needed is effective for both pain and inflammation. Acetaminophen is a good alternative if you can’t take ibuprofen.
A warm compress held against the ear can also help by relaxing the muscles around the canal and encouraging fluid to drain. For some people, alternating between a warm and cool compress every 30 minutes provides additional relief. Sleeping with the affected ear facing up, rather than pressed into a pillow, can reduce pressure and throbbing overnight.
What Recovery Looks Like
Symptoms usually start improving within a couple of days of beginning treatment. Most ear infections clear up fully within one to two weeks. Pain tends to be the first thing to ease, while muffled hearing from a middle ear infection can linger a bit longer as residual fluid behind the eardrum drains through the eustachian tube. If your symptoms aren’t improving after 48 to 72 hours on antibiotics or drops, contact your doctor, as you may need a different medication.
Warning Signs of Serious Complications
In rare cases, a middle ear infection can spread to the mastoid bone, the honeycomb-like bone directly behind your ear. Signs that this may be happening include worsening pain and swelling behind the ear, fever that doesn’t respond to treatment, and new drainage from the ear canal. Facial drooping on the affected side, persistent ringing in the ear, or dizziness can indicate the infection has reached nearby nerves or the inner ear.
Intracranial complications occur in roughly 6 to 23 percent of mastoiditis cases and can include severe headache, stiff neck, confusion, or seizures. These are medical emergencies. If you develop any of these symptoms during or after an ear infection, seek immediate care.
Preventing Recurrence
If you swim regularly and tend to get outer ear infections, a few simple habits make a big difference. Wear earplugs, a swim cap, or custom-fitted swim molds to keep water out. After swimming or showering, tilt your head to each side so water can drain, and pull your earlobe in different directions while your ear faces down. Dry your ears thoroughly with a towel. If water still feels trapped, a hair dryer on the lowest heat and fan setting held several inches from the ear can help evaporate it.
Leave your ear wax alone. It forms a protective, slightly acidic barrier that discourages bacterial growth. Inserting cotton swabs, keys, paperclips, or anything else into the canal strips away that barrier and creates tiny skin breaks where bacteria can take hold. If you think you have excessive wax buildup, have it removed professionally rather than digging it out yourself.
For middle ear infections, keeping upper respiratory infections in check is the best prevention. Treating allergies and sinus congestion promptly helps keep the eustachian tubes open. If you fly with a head cold, chewing gum or swallowing frequently during descent can help equalize pressure and reduce fluid buildup behind the eardrum.
