Neomycin/polymyxin B/hydrocortisone otic is a combination ear drop medication commonly prescribed to treat bacterial infections of the ear. It effectively combats bacteria causing the infection while simultaneously reducing inflammation, swelling, and other associated symptoms by calming the immune system.
What is Neomycin/Polymyxin B/Hydrocortisone Otic Used For?
This medication is primarily used to treat infections caused by specific bacteria, including:
- Outer ear infections: Infections affecting the external ear canal.
- Infections at the surgery site: Particularly after ear procedures such as a mastoidectomy.
It's important to note that the effectiveness of neomycin/polymyxin B/hydrocortisone otic can depend on the specific bacteria causing the infection, as some bacteria may have developed resistance to these antibiotics. The medication may also be used for other conditions as determined by a healthcare provider.
Other forms of neomycin/polymyxin B/hydrocortisone are available for ophthalmic (eye) use.
How Does It Work? (Mechanism of Action)
Neomycin/polymyxin B/hydrocortisone otic functions through a combination of its active ingredients:
- Antibiotics (Neomycin and Polymyxin B): These work by killing susceptible bacteria or inhibiting their growth. They achieve this by disrupting the bacteria's ability to produce essential proteins for survival and by weakening their cell membranes.
- Corticosteroid (Hydrocortisone): This component reduces ear swelling, redness, itching, and other inflammatory symptoms by suppressing the immune system's response in the affected area.
This medication is not effective against infections caused by viruses.

How to Use Neomycin/Polymyxin B/Hydrocortisone Otic
It is crucial to use this medication exactly as prescribed by your healthcare provider. Always follow the directions on the prescription label.
Administration Instructions:
- Wash Hands: Thoroughly wash your hands before and after administering the drops.
- Warm the Bottle: Gently warm the bottle by holding it in your hand for 1 to 2 minutes. Do not overheat, as this can degrade the medication.
- Shake Well: Shake the bottle well before each use.
- Positioning: Lie down or tilt your head so that the infected ear faces upward.
- Application: Gently pull the earlobe up and back for adults (down and back for children) to straighten the ear canal. Carefully instill the prescribed number of drops into the ear canal, avoiding touching the dropper tip to the ear, fingertips, or any other surface to prevent contamination.
- Retention: Remain in this position for about 5 minutes to allow the medication to penetrate the ear canal. If both ears are infected, repeat the process for the other ear.
- Wicks: In some cases, your doctor may insert a gauze or cotton wick into the ear canal, which needs to be kept moist with the medication. Follow your doctor's specific instructions regarding wick use and replacement.
Do not use this medication in the eyes or nose, and do not ingest it. If accidentally swallowed or if it gets into the eyes, seek immediate medical attention.
