What you use for an ear infection depends on the type of infection, where it is, and how severe it is. Middle ear infections (behind the eardrum) and outer ear infections (in the ear canal) require different treatments. Some ear infections clear up on their own with pain management alone, while others need prescription antibiotics, either oral or as ear drops.
Middle Ear vs. Outer Ear Infections
A middle ear infection happens when fluid builds up behind the eardrum and becomes infected, usually following a cold or upper respiratory illness. It’s most common in young children. An outer ear infection, often called swimmer’s ear, is an infection of the ear canal itself, typically caused by water that stays trapped in the ear after swimming or bathing. The distinction matters because the treatments are different: middle ear infections are treated with oral antibiotics when needed, while outer ear infections are treated with prescription ear drops.
When Antibiotics Are Needed
Not every middle ear infection requires antibiotics. Many mild cases in older children resolve on their own within a few days. The American Academy of Pediatrics recommends a “watchful waiting” approach in specific situations, meaning you manage the pain and monitor for improvement rather than starting antibiotics immediately.
Antibiotics are recommended right away for:
- Any child 6 months or older with severe symptoms, meaning moderate to severe ear pain, pain lasting 48 hours or more, or a fever of 102.2°F (39°C) or higher
- Children 6 to 23 months old with infections in both ears, even without severe symptoms
Watchful waiting is an option for:
- Children 6 to 23 months old with a mild, one-sided infection
- Children 2 years and older with a mild infection in one or both ears
If you choose to wait and watch, the key rule is that the child needs to start antibiotics if symptoms worsen or don’t improve within 48 to 72 hours. This approach only works if you can easily get a prescription filled on short notice, so discuss it with your child’s doctor before deciding.
Oral Antibiotics for Middle Ear Infections
Amoxicillin remains the first-line antibiotic for middle ear infections in children. The standard dose is based on body weight, typically 25 to 45 mg per kilogram of body weight per day, split into doses given every 12 hours. For children under 3 months, the dose is usually 30 mg per kilogram per day. Your doctor will calculate the right amount based on your child’s weight and age.
Adults with middle ear infections are less common but follow a similar approach: oral antibiotics when the infection is bacterial, and pain relief in the meantime. Adults generally receive a standard dose rather than a weight-based one.
Prescription Ear Drops for Outer Ear Infections
Swimmer’s ear is almost always treated with prescription ear drops that combine an antibiotic with a steroid to reduce swelling. One widely prescribed option contains ciprofloxacin (an antibiotic) and dexamethasone (an anti-inflammatory). The typical course is four drops in the affected ear, twice a day, for seven days. These drops target the bacteria most commonly responsible for outer ear infections.
For ear drops to work properly, tilt your head so the affected ear faces up, apply the drops, and stay in that position for a few minutes to let the medication reach the full length of the canal. Gently pulling the outer ear up and back can help open the canal. If the canal is very swollen, your doctor may place a small wick (a tiny sponge) to help the drops travel deeper.
Pain Relief While You Wait
Regardless of the type of ear infection, pain management is a critical part of treatment. Over-the-counter pain relievers like ibuprofen and acetaminophen are effective and often the first thing to reach for. A warm compress held against the ear can also help. These are especially important during the first 48 to 72 hours, which tend to be the worst, whether or not you’re also taking antibiotics.
Ear pain from a middle ear infection often feels worse at night when lying flat. Propping up with an extra pillow can reduce pressure on the eardrum and make sleep easier.
Home Remedies: What Helps and What to Avoid
A mixture of one part white vinegar to one part rubbing alcohol can help prevent swimmer’s ear by promoting drying and discouraging bacterial growth. You can use a clean dropper to place a few drops in each ear after swimming. This works as prevention, not treatment. Once an outer ear infection has set in, you need prescription drops.
Hydrogen peroxide is sometimes used to soften earwax, but it should never go into an ear with a perforated eardrum or ear tubes. If peroxide passes through a hole in the eardrum, it can be toxic to the inner ear and cause hearing loss. Similarly, mineral oil can soften wax buildup, but neither mineral oil nor peroxide treats an active infection. Olive oil, garlic oil, and other home remedies you may see recommended online have no reliable evidence supporting their use for ear infections and can trap moisture or irritate inflamed tissue.
Symptoms That Need Prompt Attention
Most ear infections are manageable, but certain signs call for quicker action. The CDC recommends seeking care if you or your child has:
- A fever of 102.2°F (39°C) or higher
- Pus, discharge, or fluid draining from the ear
- Symptoms lasting more than 2 to 3 days without improvement
- Hearing loss
- Worsening symptoms after initial improvement
For infants under 3 months old, any fever of 100.4°F (38°C) or higher warrants immediate medical evaluation, regardless of the suspected cause. In older children and adults, watch for pain or redness behind the ear, which can indicate the infection has spread to the bone behind the ear. This is rare but requires urgent treatment.
