Why nasal health deserves more attention
We clean our hands several times a day, but how often do we think about cleaning the inside of our nose?
Every breath brings the outside world straight into the nasal passages. Dust, pollen, pollution, and airborne germs all land on the moist lining of the nose first, before they ever reach the throat or lungs. A healthy, clean nose is one of the body’s most important defenses, helping to trap and clear out unwanted particles.
Many people now think of nasal care the same way they think about handwashing or using sanitizer. A simple routine that includes gentle cleansing of the nose can support clean breathing, reduce congestion, and fit naturally alongside other everyday wellness habits.
For some, that realization comes during a long-haul flight or a tough cold season. After one or two trips spent fighting blocked sinuses and scratchy throats, a person might start carrying an antiseptic nasal spray in a travel bag, using it before boarding a plane, after crowded events, or when family members start sniffling. Over time it becomes part of a personal wellness toolkit rather than an emergency measure.
Nasodine nasal spray sits squarely in this growing trend: using targeted nasal hygiene to support everyday respiratory health, especially when exposure to seasonal viruses is hard to avoid.
What is Nasodine® Nasal Spray?
Nasodine® Nasal Spray is an over-the-counter antiseptic nasal spray formulated for nasal hygiene and wellness. It contains 0.5% povidone-iodine (PVP-I), a broad-spectrum antimicrobial that hospitals have trusted for decades on skin and mucous membranes before surgery and other procedures.
In nasal form, povidone-iodine is delivered in a carefully balanced, low-concentration solution that is designed to coat the nasal lining and neutralize germs on contact. Instead of acting deep inside the body like an antibiotic tablet, it works right where airborne pathogens first land: inside the nose.
It’s not a cure for infections like COVID-19, but a preventive measure that helps reduce viral load in the nasal cavity.
Because Nasodine is sold as an over-the-counter nasal spray, it is positioned as a hygiene and wellness product rather than a treatment for disease. The aim is simple: help keep the nose cleaner, support the body’s natural defenses, and offer another layer of protection alongside everyday measures such as handwashing, ventilation, and vaccination.
More information about the product can be found on the Reekooz product page for Nasodine® Nasal Spray.
How clean breathing works: the science behind Nasodine®
Povidone-iodine has been studied extensively as an antiseptic. In lab tests, low concentrations of PVP-I can inactivate a wide range of viruses and bacteria, including coronaviruses, within seconds of contact. The iodine component attacks proteins and genetic material on the surface of pathogens, making them unable to infect cells.
When sprayed into the nose, Nasodine distributes a thin film of this solution over the nasal lining. This helps to:
- Promote clean breathing by cleansing the nasal passages of mucus and trapped particles
- Support daily nasal hygiene and wellness
- Deliver a non-medicated formula backed by more than a decade of research and patented science
- Provide over 160 sprays from a convenient 25 mL bottle
In practical terms, a quick spray can leave the nose feeling fresher and clearer, especially in settings where exposure to airborne germs is higher than usual.
The 0.5% PVP-I concentration in Nasodine has shown rapid antiviral activity in laboratory studies, with inactivation of viruses such as SARS-CoV-2 reported in as little as 15 seconds. This makes it a useful tool for people who want an added step between themselves and the viral cloud that often surrounds busy public spaces.
What PVP-I can do
- Neutralize bacteria and viruses before they travel deeper into the airways
- Help reduce the risk of airborne infection when used alongside other preventive measures
- Support everyday respiratory wellness during cold and flu season
How to use Nasodine® safely
Like any nasal product, Nasodine works best when it is used correctly and in line with the information on the package. It is intended for short-term or seasonal use as part of a broader respiratory wellness routine.
Suggested routine to promote clean breathing:
- Gently blow the nose before using the spray.
- Spray into each nostril two to three times per day for routine hygiene.
- Consider increasing the frequency on days with higher exposure, such as air travel, crowded indoor events, or clinical settings, without exceeding the maximum stated on the label.
- Generally suitable for ages 12 and up, and for ages 6+ under adult supervision, according to product guidance.
- Always follow the directions on the packaging.
- People with thyroid disease, known iodine allergy, or complex medical conditions should speak with a healthcare professional if unsure about use.
Occasionally, users may notice a mild tingling in the nose or a faint iodine taste at the back of the throat. These sensations usually settle quickly. Any persistent discomfort or unusual symptoms should be discussed with a healthcare professional.
Nasodine® vs. Enovid/NOWONDER™ – what’s the difference?
Both Nasodine and Enovid/NOWONDER are designed to help prevent respiratory infections by reducing the amount of virus and bacteria in the nasal passages. However, they rely on different active ingredients and slightly different concepts.
- Nasodine vs Enovid: Nasodine uses povidone-iodine, a classic antiseptic that directly inactivates a wide range of germs on contact.
- Enovid/NOWONDER uses nitric oxide, a gas that the body naturally produces, to disrupt viral replication and neutralize pathogens in the nose.
- Both are positioned as nasal cleansers and wellness tools rather than as treatments for disease.
Some people prefer iodine-based sprays because of their long track record in hospitals. Others are drawn to nitric oxide technology. A number of users incorporate both into a broader nasal hygiene routine, using Nasodine as a povidone-iodine nasal spray and NOWONDER as a nitric oxide-based cleanser on different days or in different situations.
Both products are available through Reekooz, making it easy to choose what fits your personal wellness plan.
Enovid/NOWONDER can be viewed in more detail on the Reekooz page for NOWONDER™ Nasal Cleanser.
Building a nasal wellness routine for clean breathing
A nasal wellness routine does not replace other sensible habits, but it can complement them. Many people think of Nasodine as sitting alongside items like hand sanitizer, vitamin supplements, and a good night’s sleep.

Frequently asked questions about Nasodine®
Is Nasodine® safe for daily use?
Nasodine is designed as a hygiene-focused nasal cleanser using a low concentration of povidone-iodine. Clinical experience with similar formulations suggests that short-term or seasonal daily use is generally well tolerated in healthy adults when directions are followed. Some people may notice mild stinging or a temporary taste of iodine, which usually settles promptly. Those with thyroid conditions, known iodine sensitivity, or who are pregnant or breastfeeding are often advised to check with a healthcare professional before using iodine-based products. As with any self-care product, it is best to follow the guidance on the label and avoid exceeding the recommended frequency.
Can Nasodine® be used alongside other nasal sprays?
Many people use Nasodine alongside other over-the-counter nasal products, such as saline rinses or allergy sprays, to boost their nasal health. It is generally sensible to separate different sprays by a few minutes so that each has a chance to act on the nasal lining without being immediately washed away. Directions on other products should also be followed carefully, especially if they contain decongestants or corticosteroids, which have their own limits on duration of use. If someone is using prescription nasal medication, or has complex sinus or respiratory conditions, it is a good idea to ask a healthcare professional about the best way to fit Nasodine into their existing routine.
Does Nasodine® prevent colds or flu?
Nasodine® is an antiseptic nasal cleanser, not a licensed treatment or vaccine for colds or flu. Laboratory studies show that povidone-iodine can inactivate many common respiratory viruses on contact, and that has led many people to use it as an extra barrier during high-risk times. However, no nasal spray can guarantee that a person will not catch a viral infection. Exposure level, immune status, and many other factors still play a role. The most realistic way to think about Nasodine® is as part of a layered approach to clean breathing and nasal health: it may help reduce viral load in the nose, while other measures such as vaccination, hand hygiene, and staying home when unwell remain essential for protection.
