You can take several steps to avoid otitis externa and prevent it from recurring. These are described below.
Avoid damaging your ears
- Don't insert cotton wool buds or other objects into your ears. Wax works its way out naturally and cotton buds should only be used to sweep around your outer ear (pinna).
- If earwax build-up is a problem, have it removed by a healthcare professional.
Keep your ears dry and clean
- Don't let water, soap or shampoo get inside your ears when you wash them. Wear a shower cap while you shower or bathe.
- After washing, dry your ears using a hairdryer on a low setting. Never push the corners of a towel into your ears to dry them because this can cause damage.
- If you swim regularly, wear a swimming hat that covers your ears or use ear plugs.
Treat and prevent other skin conditions
- If you develop otitis externa and you have an allergic disposition (a tendency to get allergies), tell your GP or practice nurse. Eardrops that contain certain substances, such as neomycin or propylene glycol, are more likely to cause an allergic reaction than others. Your GP, practice nurse or pharmacist can advise you about which eardrops are most suitable for you.
- If you have an allergic reaction to anything that is placed inside your ears, such as hearing aids, earplugs or earrings, remove the item. A mild allergic reaction will usually clear up on its own. Using hypoallergenic products (products that have a lower potential for causing allergic reactions) may also help.
- Seek medical advice for any other skin conditions, such as psoriasis or eczema, so they can be treated using the right medication.
- Try using acidifying eardrops or spray to help keep your ears clean, particularly before and after swimming. They may help prevent otitis externa recurring, and are available without a prescription in most pharmacies.
