What is Otitis Externa?
Otitis externa, or outer ear infection, is an infection of the external auditory canal, the tube leading to the eardrum. The infection occurs when the skin of this canal cracks and bacteria are able to enter. This condition is also commonly called ‘swimmer’s ear’ since swimming can be a cause. Use of earbuds or cleaning too vigorously with cue-tips can also damage the ear canal. Pain and swelling can become significant.
Diagnosis is made by looking at the canal for inflammation, swelling, and other signs of infection. If pulling on the top part of the ear or pressing on the notch at the front of the ear called the tragus causes pain, these can also be signs of an outer ear infection.
To properly apply the medication:
- Wash your hands with water and soap (if there’s no water nearby, use hand sanitizer).
- Tilt your head to the side toward the opposite shoulder so that the infected ear faces upward.
- Gently pull the upper part of your outer ear backwards and upwards.
- Squeeze the correct number of drops into your ear canal. The medication should adequately coat your entire ear canal.
- Lie on your side for 3 to 5 minutes OR place a cotton ball in the ear canal for 20 minutes to maximize medicine absorption.

What is an outer ear infection?
An outer ear infection, also known as ‘swimmer’s ear’, is most commonly caused by water or moisture that stays in the ear after swimming and promotes bacterial growth. It can also be caused by cotton swabs, fingers, or other objects in your ear. Outer ear infections are less commonly caused by a virus.
- Experiencing pain or fever? Take 400mg of ibuprofen or 650mg of acetaminophen every 6 hours with food, as needed.
- Protect your ear from moisture by gently wiping the outer part of the ear dry with a soft cloth towel after showering or swimming.
- Do not put anything in your ear except the ear drops I’ve recommended.
