The actions I will describe here can help reduce your viral load right at the onset of symptoms, as well as help reduce the chances of the virus taking hold and reproducing in mouth, throat and nose which are its points of entry.

Viral load dictates severity of symptoms. Even if you killed off some but not all of the virus, you would have a less severe experience with Covid.

My routine when I get home from anywhere is: wash hands, spray nose and gargle. I will cover instructions and which products to use.

Dr Pierre Kory from FLCCC said (on a Zoom call) that it takes four days for the virus to fully take hold in the human tissue of nose and throat. His technical term was the virus taking hold in the epithelial cells.

[Epithelial tissues line the outer surfaces of organs and blood vessels throughout the body, as well as the inner surfaces of cavities in many internal organs. Hence, epithelial cells are found in many parts of the body, including skin and airways.]

Here is a quote from Dr Kory from a weekly FLCCC Zoom call (link follows):

“A good practice to start right now is to gargle mouth wash. This has been shown in a number of studies to prevent not only severe illness but to [prevent contraction] of the illness.”

See it at the 14:28 minute mark in the following video:

Dr Peter McCullough confirmed this in a Zoom call I attended on 11/12/21. He said he absolutely recommends spraying and gargling [with diluted hydrogen peroxide or diluted iodine – instructions to follow] Even if you kill only some of the virus, you will fare better. He said he wishes he had known about or thought about it when he was sick with Covid – he says that’s the one thing he would change about how he managed his viral infection. During the Zoom call I asked him about nebulizing hydrogen peroxide. He said great idea! See specific instructions on nebulizing here.

Update 10/13/22:

In today’s Substack article in his blog, Courageous Discourse, Dr McCullough says,

“Thus, there is a wonderful opportunity to reduce viral replication, in fact, kill viruses with agents directly applied in the nasal cavity and the back of the throat.   Use of directly applied therapy is far more effective than swallowing pills or capsules or receiving an intravenous infusion.”

[End of 10/13/22 update]

Here is the FLCCC recommendation for only gargling in the prevention protocol. Both gargling and nose spraying are included in the Early Treatment Protocol (second image) but I made an executive decision to do both for prevention as well (wink).

Here is the FLCCC recommendation for both gargling and nose spray in the Early Treatment Protocol under Anti-Septic and Anti-Viral. Instructions are to do this several times a day.

Update 8/22/22:

Here is an excerpt from the FLCCC most recent and current protocol.

Nasal spray with 1% povidone-iodine: two to three times a day.
Sprays such as Immune Mist™, CoFix™ or IoNovo™ administered 2-3 times per day are recommended in postexposure prophylaxis and in the early phase of COVID-19 infection. Due to low level systemic absorption, povidoneiodine nasal spray should not be used for longer than 5-7 days in pregnant women. IoNovo™ contains iodine in an
amount equivalent to the daily dietary requirement and hence is safe to ingest.

Again, while FLCCC suggests steam inhalation for chronic (every day) prevention, the suggestion for nasal spray comes after exposure (post-exposure prevention). Again, my personal decision is to assume that I have been exposed every time I am in public places with other people, therefore I use this almost every day.

What to gargle with:

The FLCCC screenshot of protocol above describes the types of gargling products you should look for, those containing cetylpyridinium chloride (CPC), chlorhexidine, or povidone-iodine.

Update 8/23/22:

The following article was published in News Medical Life Sciences on 8/22/22:

Research reveals cetylpyridinium chloride in mouthwash shows anti-SARS-CoV-2 effects

“A recent study published in Scientific Reports has demonstrated the antiviral effectiveness of cetylpyridinium chloride against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.”

“These findings indicate that cetylpyridinium chloride reduces the amount of infectious virus before host cell entry.”

(End of 8/23/22 update)

I use this one, Colgate Zero.

Here is another example.

Nasal Hygiene:

Dr George Domb in California (video link below) explains how to make a nose spray with iodine – this is what I do.

There is a bit of confusion due to the fact that in the video he says to mix one teaspoon, then the article says to mix one half of a teaspoon. You could go half-way and use three quarters of a teaspoon.

Dr McCullough, when describing either an iodine solution or hydrogen peroxide solution on the Zoom call, said “If it stings or burns, it’s too strong, dilute it more.” You can just use that as your guideline.

I buy a 44 ml bottle of saline like this. If I have a hard time opening the saline bottle, I just cut off the top.

Pour the saline into a big glass measuring cup with a spout (this helps), add a teaspoon of this:


Dr McCullough mentioned Lugol’s Iodine several times as the one he recommends, but the percentages are different from povidone-iodine, so will require some calculations. Different brands are available.

Then I pour the mixture into these little bottles from Amazon which have a nice powerful spray action.

Here is another option for the spray bottles, in blue.

Xlear as a possible alternative, although not mentioned by FLCCC or by Dr McCullough.

This picture will illustrate some words in the article.

Xylitol nasal spray: An effective tool in COVID-19 prevention

Deep Dive:

Here is an article that discusses the efficacy of using a Neti Pot as an alternative (or in addition to) nasal sprays:

“The COVID-19 virus gets lodged in the nostril. It has been found that a person tests positive on the fourth day after this happens. So, the virus seems to establish a colony during these four days. We are trying to wash out the virus and reduce this colony, and hence reduce the viral load on a daily basis via this method.”

A neti pot with instructions can be purchased on Amazon:     (Neti Pot)

On the subject of Neti Pots, my friend Kevin commented:

“My wife had Covid 2-3 months ago. I regularly have used a Neti Pot using salt and baking soda for years due to allergies. During her Covid infection, I used the neti pot daily while we didn’t social distance and we even slept in the same bed. I never became symptomatic nor did I ever test positive. Reducing viral load as a mechanism of action is a common sense approach to prevention of this disease. I’m sure other factors could come into play.”


This device should give a similar effect to the Neti Pot, and seems pretty user friendly. Video instructions on the site.

(Also available on Amazon)

Update 8/14/22:

I just listened to a podcast which I very strongly recommend you listen to – hopefully, you can spare the hour!

Why do I recommend it so strongly? Because if I have not yet managed to persuade you to use nasal hygiene in your defensive and curative actions against Covid, I’m pretty sure this podcast will turn you into a believer!

Think about nasal hygiene as your first weapon for NOT getting Covid, or for NOT getting Covid AGAIN!

This podcast comes from America Out Loud:

Early Treatment Suppression and Nasal Hygiene with Nathan Jones & Dr. Peter McCullough

If you don’t want to spend the hour, click on the link above anyway, because the introduction alone is worth reading:

“First, a bit of history. From the time that Ignaz Semmelweiss first wrote about the need for physicians to wash their hands between patients and the time that it became the standard of care (or mandated because it wasn’t being done) was 150 years. Semmelweiss was ridiculed, laughed at, and discredited, but history proved him correct. Washing our hands and our nose are simple hygienic ways that we can stop the spread of bacteria and viruses.”

“Nasal hygiene is more important to our health than washing our hands. Washing our hands helps stop the spread of infections, but how often do you really get sick through your hands? Practically zero. You get sick when you touch your hands to your face, your nose, and your eyes, where bacteria and viruses can easily enter the body.”

And there’s more! The intro will link you to several studies, one of which says:

Question  What is the minimum contact time of povidone-iodine (PVP-I) nasal antiseptic required for inactivation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in vitro?”

Findings  In this controlled in vitro laboratory research study, test media infected with SARS-CoV-2 demonstrated complete inactivation of SARS-CoV-2 by concentrations of PVP-I nasal antiseptic as low as 0.5% after 15 seconds of contact…”

If you’ve read my post above this update, you already know how to make your own mix of saline and povidone iodine to create an antiseptic nose spray.

Now (for a bit more money) you can have the convenience of a pre-made nose spray:

Available here

Dr. Peter McCullough’s own words about CofixRX:

CofixRX, I believe, shortened the course of illness for my wife and importantly did not spread it to me or other people in my household, including two elderly vulnerable people…”

Another spray discussed on the podcast is Xlear (pronounced “Clear”).

Available on Amazon

If you go to the Xlear website here, you will find the following quote from a study:

Anti-Adherence of Bacteria – 1998

“This study found that xylitol blocked adhesion of bacteria to epithelial cells, showing that xylitol inhibits bacteria from sticking to tissue, which allows the body to wash them away.”

From the podcast, I understand that xylitol prevents adhesion, but the grapefruit seed extract ingredient in the spray is also antiseptic.

I still like making my own spray, because I can dilute it if it stings or burns at all. I suppose if you bought the pre-made iodine spray (Cofix) you could still add some saline to dilute it if necessary.

After hearing the podcast, I will adjust my own routine to include Xlear BEFORE I go out, to prevent adhesion of the virus, and I will continue to use the iodine spray when I return home, as I have been doing, to kill anything I might have picked up.

Update 2/26/23:

Here is a website with a recipe for Do It Yourself (make your own) xylitol nasal spray.

Advocacy with (Nurse) Michele:

Here is the recipe:

Update 2/26/23:

Dr Peter McCullough wrote another article on Substack on Xylitol nasal spray efficacy, based on a study published in July 2022.

Xylitol Nasal Spray Prevents SARS-CoV-2 Infection

“SARS-CoV-2 infection confirmed by serology was 71% lower with xylitol compared to placebo”

Update 6/11/23:

New product with research to back it up!

EXCELLENT article below gives you details! I recommend reading it for full understanding.

(Published research is listed at the bottom of the article)

One more study in addition to the ones listed in the article above:

Critical role of nitric oxide in impeding COVID-19 transmission and prevention: a promising possibility

Here is how to buy it directly from Israel:

This product is available only from Israel at the moment – and it’s pricey. ($70 for one bottle, or get together with friends and family and buy 10 bottles for $40 each.)

You can also find it on Amazon if you need faster delivery, but it is hugely overpriced ($149 for one bottle is the current price – someone is making a tidy profit.)

Be well, do well, stay well!
