Can I Leave Debrox in Overnight?

One of the most common questions when it comes to debrox is, ‘can I leave Debrox in overnight?’ And it’s understandable because clogged ears can be quite irritating. Hence if you find that leaving Debrox in for the recommended time, you might be tempted to leave it overnight.

But, leaving Debrox overnight is not a good idea. The active ingredient of Debrox is urea-hydrogen peroxide. That’s because hydrogen peroxide is a strong oxidizing agent. It can irritate and cause damage to the cells in the ear canal. This can lead to inflammation, swelling, redness, and pain.


So you should leave Debrox in for the recommended 2-5 minutes. Even if the ear wax doesn’t come out instantly, it will come out over time.

But don’t be alarmed if some solution comes out of your ears even after draining. And stop using this product if you have redness, swelling, and pain. You should also contact your primary care doctor immediately.

It’s always important to know about any medicinal substance before using it. The next segment will help you to gain a brief knowledge of debrox. 

All You Need to Know About Debrox

Here is a detailed description of the ear wax removal drop debrox. Knowing the proper dosage and side effects of it will help you to remain conscious while using it. 

What is Debrox?

There are many ways to get rid of earwax. Ear wax removal drops are one of those ways. And among them, one particularly popular one is Debrox. 

The active ingredient inside Debrox is Carbamide peroxide. Chemically, it’s urea-hydrogen peroxide. It is among a cerumenolytic. Cerumen means ear wax and lysis means to break off. So, these are chemicals that can clear ear wax.

Carbamide peroxide is a white crystalline substance. It is colorless, odorless, and is soluble in water. It has a 1:1 ratio of urea to hydrogen peroxide. By itself, hydrogen peroxide solution is unstable. So, using urea, this product is stabilized.

You’ll see the use of carbamide peroxide in many places. It is used as a dental bleaching agent as well as a disinfectant. It is also used in the laboratory as a replacement for hydrogen peroxide.

However, Debrox is specialized in earwax removal. And Debrox is an over-the-counter drug available in most pharmacies.

How Does Debrox Work?

The active ingredient of Debrox is urea-hydrogen peroxide. In fact, most of the cerumenolytic agents are some form of hydrogen peroxide. So, it is this compound that helps loosen the earwax.

When you apply Debrox, the solution seeps into your ear wax. Coming in contact with your skin and earwax, carbamide peroxide breaks down into hydrogen peroxide and urea. The hydrogen peroxide then releases oxygen. This reaction might make some bubbling or frothing sound.

This oxygen gas is formed within the earwax (as the solution went inside the earwax). Being a gas, oxygen is lighter and occupies more space. So, it expands and breaks off the earwax from the inside.

This loosens the hard ear wax. So it’s easier for the softer earwax to then come out. Your ears have a natural mechanism to clear earwax. Once Debrox does its job, your ears can clear the softened ear wax gradually on their own.

In some cases, the ear wax might not get out on its own. In that case, irrigation inside the ears might be necessary.

How to Use Debrox?

The instructions on how to use Debrox can be found on their packaging. So you should follow them accordingly. Below are the general instructions to apply Debrox:

  • If you’re applying this for the first time, you have to ensure that you don’t have commitments later on. That’s because using this for the first time can cause dizziness and minor headaches.
  • It’s best to have someone else put the drops in your ears. That way, you can ensure that all of the solution is going into your ears. However, it is possible to give it on your own if there’s no one else around.
  • Keeping your head tilted horizontally is preferable. So, you can try lying down on a pillow. Or sit down and rest your head horizontally on a soft surface. Needless to say, your affected ear will be facing up.
  • You have to pull back on your ears to ensure that the drops go through easily. Our ear canals are not horizontally straight. In fact, they are slightly curved. So you have to pull backward and upwards on your ears to make it more or less straight.
  • Then you or the person giving the drops have to align the nozzle of the bottle to your ears. However, it’s advisable that the bottle doesn’t touch the ears.
  • Finally, put 5-10 drops of Debrox into the ear canal. You might notice a fizzing sound in your ears. That’s completely normal. In fact, it’s an indication that oxygen gas is being formed. And that’s what will help clear out your ear wax.

Debrox Ear Drops Dosage

Debrox ear drops consist of a 6.5% solution of Carbamide peroxide. They come in 15 ml or 30 ml bottles.

The recommended dose is 5-10 drops per use. And you have to leave it for two to five minutes. You have to do this twice a day for up to four days.

Oils can soften ear wax. This can make it easier for the ear wax to come out. So, if you’re in a pinch, then you can try using oil.

If your ear wax doesn’t fall off automatically, you can irrigate with warm water or oil. However, your doctor will know what’s best for you. So, if they instruct you otherwise, then it’s best to follow what they say.

Debrox isn’t recommended for children under twelve years of age. So, if your child has clogged ears, you have to look at other options which we will be discussing later.

Side Effects of Debrox

Normally, Debrox has minimal side effects. This is a topically applied drug. So, it’s not absorbed into your blood. Hence, you can expect minimal side effects.

However, there may be some local side effects. Some mild side-effects include:

  • The feeling of fullness in the ear
  • Fizzing sound
  • Slight itching

These are normal. And if you can tolerate them, then they’ll not cause any harm. However, some more serious side-effects include:

  • Dizziness
  • Pain
  • Swelling
  • Irritation
  • Allergic symptoms like rash, fever, hives, etc.

You should stop using the product and consult with your doctor immediately.

Other Ways to Clear Ear Wax

Debrox isn’t the only way to clear out ear wax. There are several at-home remedies you can try. Some of them are given below:

Using Different Oils

Oils can soften ear wax. This can make it easier for the ear wax to come out. So, if you’re in a pinch, then you can try using oil. Some of the oils that you can try include glycerin, coconut oil, olive oil, etc. Warming the oil up a little bit greatly improves the chances of getting the ear wax out.


Sodium Bicarb or Baking Soda

Baking soda is something that’s likely sitting in your kitchen pantry right now. You can dissolve a quarter of a teaspoon of baking soda in 30 ml warm water. Then you have to apply it to your ears much like Debrox using a dropper.
Baking soda gives out carbon dioxide gas. This works in a similar manner to Debrox. The air inflates inside the ear wax making it loose.


Irrigation with Water:

Sometimes, plain water can do the trick. Using warm water, you can try irrigating your affected ear. The water can soften the wax. Then, it may come out on its own. However, there’s a good probability that it won’t work.

Instruments Used by Doctors

Doctors use a variety of instruments to clear out ear wax. They can flush out the wax by electronic irrigation using water or other fluids. Sometimes, they may even use suction to clear out the wax by an ear vacuum. 

And in some cases, they might resort to ear wax softeners before mechanically removing the ear wax.

Don’t Use Cotton Buds:

You may be tempted to use cotton buds to clean out ear wax. However, if your ears are already clogged, then a cotton bud will push the wax further inside. This will make the ear wax even harder.
