If you have ever experienced a sinus infection, you likely have felt true pain. The bones surrounding the nose and eyes and in the cheeks are lined with membranes that function to produce mucus and filter germs. However, when congested, these membranes are unable to drain properly, causing inflammation, congestion and pain. While a variety of treatment options are available for the condition, hydrogen peroxide is one of the safest and most effective.

The Problem with Common Treatments

Typical mainstream treatments include antibiotics, anti-inflammatories, steroids and even surgery in some cases. The main problem with many of these treatments is their abrasive nature. Rather than working at the root of the issue to relieve the condition, they affect the body by eliminating fluid production and altering the natural fluid balance of the body. This generally causes more adverse effects in the future. People also develop an immunity to these treatments, making them less viable options for future treatment.

A Better Alternative

Hydrogen peroxide, on the other hand, is a safe, natural alternative. Its natural composition makes it an effective remedy for sinus infection without extensive treatment. These five reasons illustrate why it is such an effective treatment option.

1. Relieves Congestion

One of the most important reasons to use this option is that it safely and effectively relieves congestion. Used as a rinse, it cleanses the sinuses and alleviates the condition.

2. Eliminates Infection

Hydrogen peroxide has the added benefit of eliminating infection. It is a natural antibacterial agent.

3. Controlled Concentration

While the appropriate concentration to use in this treatment is 3%, the concentration can be controlled even further by adding additional water to the solution. This control prevents adverse effects.

4. Cost Effective

One bottle of hydrogen peroxide is more than enough to treat multiple sinus infections and is available at a very low cost, especially when compared to other treatments.

5. Non-Habit Forming

Many traditional remedies create a reliance effect in the body during which the body requires more and more of the treatment to get the same effect. Hydrogen peroxide does not have this habit forming effect on the body.

Hydrogen Peroxide Treatment for Sinus Infections

To use hydrogen peroxide, mix four parts filtered water with one part 3% hydrogen peroxide. Irrigate the nose using a spray bottle or neti pot.

While a variety of different sinus infection treatments are available, hydrogen peroxide is one of the most effective options. It safely relieves congestion and eliminates infection without forming dependence.

I had a terrible sinus infection in the left side of my face. No mucus but pain up into my nose, down into my jawbone, teeth and neck. Couldn't sleep on that side or the pain would flare up for hours. I use hydrogen peroxide for a lot so I put it in water in the neti pot tonight ( couple of tablespoons?) Pain gone. Slept on that side all night with. No problems. Hardly any tenderness in face. Plan on doing this concoction for the next few days, few times a day. Eureka! Magic cure. Put some down in ears on qtip after reading this... mucus I didn't even know I had back of throat loosened up ( allergies).

So today is my fifth day, I have felt no relief from congestion, and today when I blew my nose (before using the neti pot), I saw blood. I am using the neti pot, the included solution, and one teaspoon of 3% hydrogen peroxide, three times a day. should I stop or am I on the right track?

You're on the right track! Continue flushing! until the blood film is gone and ultimately it clears out in few days..

My hubs had a constant severe sinus infection for 3 months. He had a very bad headache. He went to 3 different doctors and 2 runs of antbx. with only 1-2 days of relief. Also a chiropractor, without results. Used flonase, and claritan daily, took 3 tumeric and fishmox daily. No relief. We began to wonder if he had a tumor.

He was desperate, so he tried 4 parts distilled water to 1 part 3% hydrogen peroxide, flushed sinus with neti pot and then let it bubble in nose for 5-10 minutes, (burns a little). Suddenly a profuse amount of mucous began to bubble out, flushed several times, and let it set afterwards each time, at which each time large amounts of thick mucous bubbled out of his sinus. All through the day, it would continue to pour profuse amounts of thick mucous.

This was finally the answer, Praise God some relief.

I just did the hydrogen peroxide for sinus infections remedy -- it stings like hell. However, it did relieve my congestion. It remains to be seen whether it killed the infection. I'll do it 3-4 times daily over the next several days.

Tulov, dilute the h2o2. It should work just as well but without the sting.

I heard that adding some salt to this hydrogen peroxide solution relieves the stinging. And it does.

Hi- just wanted to comment about a sinus infection I had for over a year and had tried everything...literally. I put a few drops of 35% food grade HP & distilled water in one of those humidifiers that make the mist, and would breathe in through nasal and mouth- and within 3 days I was finally cured after suffering for a year.

I am highly allergic to cedar and elm pollen and living in Houston, does me no favors! For the past three weeks, the two pollen's have wreaked havoc on my sinuses, which in turn, turned into a nasty sinus infection. I have been getting chills on and off, waking up every morning about 12:30 blowing my nose and hacking. I could smell and taste infection and was hacking up and blowing thick green stuff. I wouldn't be able to fall back to sleep until about 4ish. I have to get up at 5:30 for work. I have been feeling sick, tired and cranky. All of these years that I thought that it was my lungs giving me problems, but I think it has been chronic sinus infections! I don't have insurance, so going to the doctor to get antibiotics is out of the question as I am on a super tight budget.

I decided to come here and saw the Hydrogen peroxide cure and decided to take a shot in the dark.

I have a plastic neti pot. I know that table salt is a no-no, but it's what I had available, so that is what I used.

I used 1/4 teaspoon of salt and two teaspoons of hydrogen Peroxide in warm distilled water and cleaned out each nostril.

I did that when I got home from work and did it again before I went to bed. I also did it this morning before work.

The "sick infected" feeling that I had along with the chills; GONE! I slept all night! I could taste my food again and could smell again which told me that my husband had lied to me about smoking in the house, because I smelled it! He got an earful! LOL!

I will do this again when I get home from work. I am in awe of this inexpensive and highly effective treatment! For about $1.00, I am almost 100%, where a visit to the doctor along with scripts, would have cost me about $400 or more.

Hydrogen peroxide should be diluted at least 10-20 times its normal (3%) strength. A 4:1 dilution as stated here will burn your nasal mucosa severely and delay healing from the sinus infection. There is no good medical evidence for its use in the nasal sinuses. I am a doctor who has tried hydrogen peroxide and suffered mucosal damage with a 4:1 dilution with water.

Replied by Erica

I used hydrogen peroxide to clean my nose but I didnt dilute it and now I can't smell is this normal. I did it before reading this website I didnt know you had to dilute it.

VERY true: 4:1 will be too strong and burn. It'll leave your sinuses irritated, and you with a lot of discomfort. You may very likely get nose bleeds. Dilute at a higher ratio... the 10:1 sounds okay... I'd go higher.

Replied by Jim

but we are talking about 3% not 35%, the product is already @3%, so why the ratio 4:1 could be too concentrate?

I developed a sinus infection after battling pneumonia and the flu for a month. It started, of course, on a weekend. My face could barely be touched and my teeth ached so badly--- down to the jawbone. I was using hydrogen peroxide to rinse my mouth and throat and wondered if I could use it in a Neti pot. Thank you Earth Clinic for the confirmation of how to use it! I have used 3% hydrogen peroxide and distilled water, 1/2 and 1/2 in the Neti pot three times today. (10am-1pm-4pm.). Second and third time got better each time, face quit hurting, tmj joint pain almost gone and teeth feel like the fever they had in them is dissipating. Got a ways to go, it was bad! I'm on my way--thank you again!

You know, all of these comments sound sort of complicated.

Here's what I do: dip a couple of cotton swabs in h2o2. Insert the swabs into the nostril at a time (I do both at the same time.) Ease the swabs back until only an inch is sticking out...and leave them for a minute or so. (Often it makes me sneeze.)

After you remove the swabs give your nose a good blow. Voila! I do this two or three times a day if I'm sick. It's definitely great before bed if you're congested. And it keeps a sinus infection from grabbing hold.

I get sinus infections at least twice a year. I think it is tied to my allergies and after a long lapse of sleep. Not to be gross but when I know I have an infection I go ballz-to-the-wall with the H-Peroxide mix with the neti pot. It works. 1/4 of the mix is H-Peroxide. Hurts a bit but gets results. Nothing like seeing yourself blowing out an infection in the sink! Sometimes there is a little blood mixed in with the green mucous but I think that's normal when the infection is pretty bad.

I have used hydrogen peroxide for sinus infections and it does work. You need a neti pot, I use the one from the chemist that comes with the saline sachets. Put 1/2 to 1 sachet into the pot and dissolve with small amount of really hot water. Then top up to a warm water temp up to the line marked on the bottle.

Then mix in a teaspoon of Baby Shampoo and give it a shake to make it sudsy. The baby shampoo will help to dissolve the bio films that protect the bacteria from both the salt solution and antibiotics.

Use this to rinse your sinus, but especially hold some of the mixture in, tip you head upside-down and really let the mixture get into the upper sinus. Breath in through your nose at the some time to bubble and wash the mixture. Tilt your head one side for 20 seconds, then the other. Let the mixture out, then squeeze some more up there, but this time hold your head parallel to the floor then tip one side for 20 seconds, then the other. This will address the sinus cavities under your eye sockets. Use up remaining mixture to flush.

Then you need to mix another neti pot mixture adding some peroxide.

Start with 1/4 teaspoon of hydrogen peroxide and go up from there depending on tolerance. Repeat whole procedure to target upper and middle sinus cavities.

People have posted about the pain of the sinus wash. I can tell you that when your sinus is infected the wash does hurt. Just washing an open wound would hurt or sting. But...if your sinus is healthy, it does not hurt. You can feel the peroxide bubbling and oxygenating, but it's not at all painful. So with your sinus infection, start with a small amount of Baby Shampoo and Peroxide and work up to larger amounts. As your sinus begins to heal, you will find you can tolerate more of the peroxide.

I would like to add, when you use peroxide, it doesn't just wash out the bad bacteria, it washes out ALL bacteria, good and bad. So it's a good idea to use some probiotics. Some people put the probiotic powder into a saline solution and flush the sinus to in the hope that some of the probiotics will stay put and re-colonise the sinus with good bacteria. I personally put the powder on the back of the tongue at night when I'm going to sleep and let it naturally migrate its way up into the sinus.

- Hope this helps. xx

Hi, thanks for the information. Is it necessary to dilute the 3% hydrogen or use it straight? Regards, Catherine

Thanks for confirming what I have done with peroxide from my own gut feeling.

Dear people, before you make an affirmation please read some more materials about the subject. Quote : the hydrogen peroxide do not wash the bad and good bacteria, why so?? because good bacteria thrive when is plenty oxygen and bad one thrive when your body has less oxygen than 60%.

I am currently 54 years old and have had problems with getting prolonged and painful secondary sinus and ear infections along with every cold or flu I contract, ever since I was a kid. I have eczema and a few allergies so, over the years, I have been prescribed so many different courses of cortisone and antibiotics that by mid adulthood my poor immune system was pretty much shot. It seemed as if there was a bug within 10 miles of me, I would catch it. I was just tired of it.

So, last year, after speaking with a friend who had much success boosting her own immune system by using probiotics, I decided to also give probiotics a try and vowed to commit to using natural therapies whenever possible to try to boost my immune system back to health. And then, just as things seemed to be going so well, I caught an aggressive upper respiratory bug that was going around my office. As was typical for me, the virus itself ran its course in about 7 or 8 days, but I was left with a horrible sinus infection that just seemed to keep hanging on and was getting worse. It was making life miserable an just about knocked me out.

Since it was the height of cold and flu season, I was unable to get an appointment with my doctor, who would have just prescribed antibiotics for the sinus infection anyway, something I had worked the whole year to avoid. Then, I stumbled across an article about adding 1 tablespoon of hydrogen peroxide to your regular neti pot solution and thought what the heck, I would give it a try.

The formula is this: I empty one dry saline mix packet (I get the over-the-counter packets, they're pre-mixed, easy to use and buffered right so they don't sting) into a clean, sterile neti pot first, add 1 tablespoon hydrogen peroxide (no more than that or it will be uncomfortable and could irritate the lining at the back of the nasal passages), then fill the rest of the pot to the inside rim with distilled water, put the lid on and give it a few shakes to mix it well. Then use the rinse as usual. I do half the solution on one side of my nose, then switch and use the remaining half of the solution on the other side, for a full sinus rinse.

I did this 3 times a day for 5 days - Once when I got up in the morning, once when I got home from work, and once right before bedtime. I could immediately feel (and see) the difference when adding the hydrogen peroxide to the neti pot rinse.

Within 3 days the sinus infection was gone and within 5 days the swelling in my nasal passages had abated and my nasal muscus was back to clear. After that, my cough cleared right up as well because I had no more infection seeping down into my lungs from the sinus infection.

I have not had a sinus, ear or lung infection since. I continue to add a tablespoon of hydrogen peroxide to my regular neti pot solution in this way whenever my sinuses feel a little "iffy." It could be allergies, or it could be a virus. Either way, adding in the hydrogen peroxide has worked wonders for me.

In addition to this sinus rinse, I also use several drops of straight hydrogen peroxide in each of my ears for about 10 minutes each side to ward off cold and flu whenever I have been exposed to sick people. It works great to keep the ear canal clean and free of wax buildup, too.

I am a firm believer in hydrogen peroxide and its healing properties and I will also be adding Bill Munroe's inhalation technique to my repertoire of holistic remedies in the future.

I was suffering from a sinus cold past few days and decided to try this H-P and sea salt treatment and within one day was 75% and next day 100%. Thanks for everyone's advice and it worked without medication like a miracle. It will be a Merry Christmas after all.

I am so happy to read about these cures. We've had some chronic illness here in our home and it's been devastating for us all at times. Diet seems to need very careful scrutiny most of the time; husband doesn't have the energy to buy into- that so we go round and round. Of course he has been coughing most of the last 4 weeks.

Anyhow, I myself have experienced huge and very fast success with the coconut oil rinse especially the "pulling" technique in the mouth which has gotten rid of a giant canker sore (from the grapeseed extract btw) and eliminated the cough almost entirely for me! Also the hydrogen peroxide really helped my ears.

My sons hate the idea of any oil at all, so I know the oil and ACV will be unwelcome. One has bad stomach cramps now too so I'm not sure what to do? Grapeseed and elderberry could be making it worse (both have been part of their regimen for the last couple months but they try to avoid it sometimes)? I opted to put coconut milk in his roobis tea which he likes....Any other ideas? Thank you!

I am so glad to find this site. I tried 1 Tbsp. hydrogen Peroxide to 1 ounce water. Q-tip application to each ear and nasal passages (separate q-tips for each of course). That felt a bit better, so I followed that with a few drops in each nostril and tilted head back for 10 seconds. There was clearing. Not much tingling. Followed all this with 2 good gargles. I feel better and can breathe. I think I'll do this morning and night and see how it goes. Thanks again.

After reading this post I decided to give peroxide a try. After putting a couple of drops in each nostril I felt immediate relief from the throbbing pain in my face. The peroxide though had a burning sensation for about a few seconds it nevertheless did the job.

I used to get sinus infections about twice per year, but have been using hydrogen peroxide successfully for 3 years now and have not needed antibiotics. I use the 3% solution one can obtain at the pharmacy and dilute it to one part hydrogen peroxide to 15 parts warm water. (This avoids excess irritation.) I do this in a little medicine measuring cup and then suck it into a child's medicine syringe. (Both these items can be purchased for little cost at any pharmacy.) Then I get on my hands and knees on my carpet and inject the mixture up each nostril. Then I put my head down which keeps the solution in my sinuses and keep that position for 4 to 5 minutes. I have found that I usually need to do this 2 days in a row and the infection is completely eliminated. I love it. It is a miracle after struggling for so many years. Hope this works for you as well.

I use a 16 oz Neil Med bottle, two packets of the additive, and just enough 3% hydrogen peroxide to cover the bottom of the bottle. I will never go back to the Dr. for a sinus infection again; works WAY better than antibiotics, and quicker too; costs almost nothing. This and some HP dropped in my ears along with the expanding foam earplugs, & I get over infections and colds MUCH more quickly. I drain it after about 15 minutes. No stinging or pressure. I have tried it with just 3% HP, and that is a bit harsh; but it DID attack the infection. I'd use it the new way about 5-6 times a day; It's less time than it takes to go to the Dr.'s office!

So. I'm on day 8 of a sinus infection. I've had them stop chronically for so long that I am immune to antibiotics. My new holistic Dr. gave me a natural which I have been using. I am currently using a saline rinse but he mentioned peroxide treatment if I wasn't better in a few days. Since he us closed on Friday through the weekend, I've not been able to reach him to ask about it so I found myself here. Most people are talking about snorting and there are a variety of dilutions. I'm wondering about simply replacing saline with peroxide for a rinse and if so what the ratio should be. Been in bed for a week! Help!

I had a cold; my sinus was congested and horrible sneezing and runny nose, so I took a Q-tip and saturated it with H-P and swabbed as far up as I could reach and snorted. Intense reaction followed by clearing of the nasal storm ... Amazing what the extra oxygen can do.
