Hydrogen peroxide in ear: how to use it and adverse effects

Keeping your ears clean is a key part of maintaining your overall health and well-being. Many people utilise cotton buds for ear cleaning, but this method can push earwax further down into the ear canal and result in obstructions and possible hearing impairment. Moreover, failing to clean your ears regularly can lead to the accumulation of bacteria and fungi, potentially leading to ear infections. An alternative to this, which has gained traction in recent years, is using hydrogen peroxide for ear hygiene.
In this guide, we'll delve into the correct application, potential side effects, and alternative strategies for good ear hygiene. It can also be potentially used for removing blackheads in the ears.
How does hydrogen peroxide function in your ears?
Hydrogen peroxide is a colourless fluid widely utilised as a sterilising agent and bleach. When used in the ears, it aids in the breakdown of earwax and elimination of detritus. The chemical reaction that happens when hydrogen peroxide interacts with earwax causes it to fizz, which can help to loosen and eject the wax.
Hydrogen peroxide for ear infection and earwax
Hydrogen peroxide can be an effective remedy for both ear infections and earwax buildup. It kills the bacteria responsible for the infection and softens the earwax, making it easier to remove. Furthermore, hydrogen peroxide solution can be used to treat other ear-related conditions such as swimmer's ear and tinnitus. Using this solution can help prevent ear infections. However, it should not replace good hygiene practices.
Instructions for cleaning ears with hydrogen peroxide
To utilise hydrogen peroxide for ear infection and earwax removal, follow these instructions:
- Combine equal parts of hydrogen peroxide and water
- Lie down on your side with the ear needing treatment facing upwards
- Use a dropper to introduce a few drops of the mixed solution into the ear canal
- Wait for a few minutes, allowing the hydrogen peroxide mixture to soften the earwax or kill bacteria
- Tilt your head to the side and allow the solution to flow out of your ear
- Gently clean the outer ear with a cotton bud or cloth
Is it safe to put hydrogen peroxide in your ear?
If you're wondering, can I put peroxide in my ear? The answer is yes.
Compared to other ear cleaning strategies, such as ear candles or cotton buds, Hydrogen Peroxide is a safer and a more efficient choice. Ear candles can cause burns and other injuries to the ear canal, while cotton buds can push earwax further into the ear canal, causing blockages and other complications.
How long to leave hydrogen peroxide in ear?
Once accustomed to the sensation, allow the solution to bubble and fizz in your ear for up to one minute. Initially, you might only be comfortable with this feeling for a few seconds. Afterwards, tip the solution out onto a tissue. The ear canal should naturally dry within the next minute or so.

Why does hydrogen peroxide fizz in the ear?
Ear drops may include various substances such as hydrogen peroxide or other compounds designed to soften earwax. A prevalent type of hydrogen peroxide used in these drops is carbamide peroxide. This substance reacts with the earwax, releasing oxygen and causing the wax to bubble.
If you're asking yourself "Why does my ear crackle when I put hydrogen peroxide in it?" or "What happens when hydrogen peroxide touches ear wax?", remember that you'll hear fizzing or popping sounds and possibly feel an itch inside your ear. This is an indication that the hydrogen peroxide is activating and breaking down wax buildup.

Safely introducing hydrogen peroxide into your ear
Before you use hydrogen peroxide in your ear, there are some safety measures to keep in mind. Firstly, ensure the hydrogen peroxide solution hasn't expired. Expired hydrogen peroxide can be ineffective or even detrimental. Secondly, it is crucial to dilute the solution with water before introducing it into the ear. Undiluted hydrogen peroxide can cause irritation and even damage to the ear canal.
To safely put hydrogen peroxide in your ear, adhere to the following steps:
- Dilute the hydrogen peroxide solution with water. A mixture of 3% hydrogen peroxide and 97% water is recommended.
- Lie down on your side with the ear requiring treatment facing upwards.
- Using a dropper, deposit a few drops of the diluted hydrogen peroxide solution into the ear canal.
- Let the solution sit in the ear for a few minutes. You might hear a bubbling or fizzing sound, which is normal.
- Tilt your head to the side allowing the solution to drain from the ear.
- Use a clean, dry cloth to wipe away any remaining solution or moisture.
There are additional tips to help ensure effective ear cleaning. Firstly, avoid using cotton buds or other objects to clean inside the ear canal. These can push wax deeper into the ear canal, causing blockages and other complications. Instead, use a soft cloth or tissue to clean the outer ear.
Also, avoid using ear candles or other unconventional methods for cleaning your ears. These methods are not backed by scientific evidence and can be hazardous.
Potential adverse effects of using hydrogen peroxide in ear
Generally, hydrogen peroxide is considered safe for ear use but it can cause discomfort and a burning sensation in the ear canal if not adequately diluted. Also, it's crucial to avoid a frequent or extended use, as it may harm the sensitive tissues of the ear.
Some may encounter side effects like dizziness, nausea, and experiencing a ringing sound in the ears while using Hydrogen Peroxide for ear cleaning. If these symptoms continue or get worse, immediate medical consultation is necessary.

When to seek medical help
Hydrogen peroxide can indeed be an effective solution for some ear-related issues. However, if you experience any of the following symptoms, it's essential to seek medical help:
- Intense pain or discomfort in the ear
- Fluid draining from the ear
- Fever
- Dizziness or feeling of spinning (vertigo)
- Loss of hearing
Other methods for cleaning ears

Maintaining ear hygiene is vital and selecting an appropriate method for ear cleaning is crucial. Although hydrogen peroxide is often chosen for this task, it may not be the right fit for all.
Here are some other methods to consider for ear cleaning.
Olive oil
Olive oil offers a natural and safe substitute to hydrogen peroxide for ear cleaning. It functions by softening earwax, thereby facilitating easier removal. However, it has certain associated risks. Should you have an ear infection or ruptured eardrum, it's advisable to refrain from using it as it might exacerbate the situation. To employ olive oil for ear cleaning, slightly heat the oil before dropping a few drops into your ear.
Saline solution
Another effective and safe substitute for hydrogen peroxide for ear cleaning is a saline solution. This method aids in expelling earwax and debris from the ear canal. To use a saline solution for ear cleaning, add a teaspoon of salt to a cup of warm water, then drop a few drops of this solution into your ear.
Warm water
Warm water serves as a simple yet efficient substitute for hydrogen peroxide in ear cleaning. Like saline, it helps in expelling earwax and debris from the ear canal. However, some risks come with using warm water for ear cleaning. If the water temperature is too high, it could result in burns or damage to the ear canal.
Additional alternatives
There are various other alternatives to hydrogen peroxide for ear cleaning, including ear drops, ear candles, and ear irrigation.
- Ear drops function by softening earwax, facilitating easier removal. The benefits of using ear drops for ear cleaning are their ease of use and availability. On the downside, they might not be effective for everyone and may cause irritation or allergic reactions.
- Ear candles work by creating a vacuum that draws out the earwax. The benefits of using ear candles for ear cleaning include their non-invasiveness and the relaxation they provide. However, their effectiveness isn't scientifically proven, and they may cause burns or ear canal damage.
- Ear irrigation aids in flushing out earwax and debris from the ear canal. The benefits of using ear irrigation for ear cleaning include its effectiveness in flushing out earwax and debris. However, it should be performed by a healthcare professional only, and incorrect application can cause damage to the ear canal.
