Can a nasal spray help prevent COVID-19? Looking at the science of CofixRX

(WXYZ) – A Detroit subway company said they’ve created a nasal spray that can help prevent COVID-19.

It’s called CofixRX, and a spokesman said the product’s active ingredient is iodine, a substance often used topically on patients before surgery.

The spray was developed by eight board-certified physicians, some right here in Michigan. I tried it myself, and had no visible or immediate side effects, just a strong, chemical-like odor.

There are legitimate medical studies that support its effectiveness, but none of these studies were performed on humans. It is also sold at several pharmacies in metro Detroit.

At Notre Dame Pharmacy in Grosse Pointe, CofixRX is a bestseller. Owner Bill Kemanski began wearing it in his store back in December. He said customers take the trip here just to get their fingers in it.

“I have repeat buyers, especially the grandmothers and mothers who buy it for their children at school,” Kemanski said.

The active ingredient is povidone iodine, an antiseptic commonly used on a patient’s skin before surgery.

A 2020 study in the Journal of the American Medical Association said povidone iodine kills 99.9% of SARS-CoV2, the coronavirus that causes COVID-19.

The nasal spray itself also contains other ingredients and it has not yet reached the human clinical trial phase.

“I talked to some medical friends and they say, ‘yes, that makes good sense.’ Does it protect against or not? We never know, but it’s definitely a product that is on the way,” Kemansi said.

Beaumont Infectious Disease Expert Dr. Matthew Sims is a self-proclaimed skeptic. Mainly because the nasal spray has not been approved by the FDA, and in his opinion, the scientific backing is insufficient.

“It’s fair to say you do not recommend these products to patients?” I asked Sims.

“I’m not. I recommend the things that have been proven, what do we know we prevent it. We know the vaccine prevents it and that boosters make it even better,” Sims said.

CoFixRX packaging is clearly labeled with a reminder that the product is not intended to replace vaccines. Kelly Goldberg said she is boosted but is not opposed to trying alternative treatments and preventatives. Her advice is to do your research.

“I think listening to our scientists and our health experts is the best way to protect ourselves right now,” Goldberg said.

The preventive measure is recommended for people who are in overcrowded areas where COVID-19 transmission is high.

According to a study from Utah University, it works for up to eight hours and is supplemented with the use of masks.

In a statement to 7 Action News, CofixRX CEO Dennis Kaiser wrote:

“CofixRX Nasal Spray is a safe and scientifically proven over-the-counter povidone iodine nasal spray developed by a team of eight board-certified physicians determined to provide an easily accessible way to fight bacteria and pathogens. CofixRX Nasal Spray is designed to provide an additional layer of exposure protection to reduce the likelihood of infection or transmission.

Independent research from Utah State University’s Institute for Antiviral Research confirmed that CofixRX nasal spray is extremely effective against SARS-CoV-2, influenza and the common cold virus.

Our goal is to provide people with a product that is safe and supported by science to help them feel more comfortable, especially in situations where social distancing is difficult.

CofixRX Nasal Spray is manufactured in an FDA-approved facility in Rochester Hills, Michigan and can be purchased at more than 500 pharmacies, medical offices and health stores nationwide.
