SaNOtize NOWONDER Nasal Cleanser Unapproved New Drug Warning
Summary
FDA issued a Warning Letter to SaNOtize (Vancouver, BC) and its US subsidiary NoWonder, Inc. (Sandy, UT) on April 17, 2026, for marketing 'NOWONDER Nasal Cleanser' as an unapproved new drug in violation of Section 505(a) of the FD&C Act. The product, which claims to use nitric oxide to fight viruses and bacteria including influenza and SARS-CoV-2, has no FDA-approved application. FDA requires a written response within 15 working days detailing corrective actions or justification for continued marketing.
Firms marketing nasal sprays, respiratory products, or supplements with antimicrobial or immune-modulation claims should audit their labeling for disease-treatment claims. FDA's drug classification turns on intended use as established by labeling—claims about fighting specific pathogens (influenza, SARS-CoV-2) are a clear enforcement trigger. Companies should verify GRASE status or NDA approval before marketing such products in US commerce.
About this source
FDA Warning Letters are public notifications to firms the agency believes are significantly violating FDA regulations. Common triggers include Current Good Manufacturing Practice violations, unauthorized drug claims, substandard clinical trial conduct, unapproved marketing, and tobacco sales to minors. Letters require a written response within 15 working days. Around 75 letters land each month across drug manufacturers, medical device makers, tobacco retailers, and dietary supplement companies. Watch this if you run a regulated manufacturing operation, advise on FDA compliance, defend companies in enforcement matters, or track quality-system failures that precede recall events. GovPing publishes each letter with the recipient, agency division, and cited violations.
What changed
FDA determined that NOWONDER Nasal Cleanser is a 'new drug' under Section 201(p) of the FD&C Act because it is not generally recognized as safe and effective (GRASE) for its labeled uses. The product's labeling makes drug claims—including statements that nitric oxide 'inhibits replication of harmful viruses, including influenza and SARS-CoV-2'—that establish intended uses as a drug under Section 201(g)(1)(B). Because no approved FDA application exists under Section 505, introduction of this product into US interstate commerce violates Section 301(d).
Manufacturers and distributors of nasal sprays, dietary supplements, or consumer health products making immune-support or antimicrobial claims should review their labeling against FDA's drug/cosmetic/supplement classification framework. Any product making disease-treatment or pathogen-killing claims faces similar enforcement risk. Firms receiving Warning Letters have 15 working days to respond before escalation to seizure and injunction.
What to do next
- Respond in writing within 15 working days of receipt of this letter with specific steps taken to correct any violations
- Include an explanation of each step being taken to prevent the recurrence of violations, as well as copies of related documentation
- If you cannot complete corrective action within 15 working days, state the reason for the delay and the time within which you will complete the correction

WARNING LETTER
April 17, 2026
RE: 727784
Mikael Svensson:
This letter is to advise you that on February 17, 2026 the United States Food and Drug Administration (FDA) reviewed your product labeling, including your websites at the internet addresses https://www.nowonder.com/ and https://sanotize.com/ where your “NOWONDER™ Nasal Cleanser” is available for purchase in the United States without a prescription.
“NOWONDER™ Nasal Cleanser” is an unapproved new drug introduced or delivered for introduction into interstate commerce in violation of section 505(a) of the Federal Food & Cosmetic Act (FD&C Act), 21 U.S.C. 355(a). Introduction or delivery for introduction of such a product into interstate commerce is prohibited under section 301(d) of the FD&C Act, 21 U.S.C. 331(d). These violations are described in more detail below.
Unapproved New Drug Violations
Your “NOWONDER™ Nasal Cleanser” is a “drug” as defined by section 201(g)(1)(B) of the FD&C Act, 21 U.S.C. 321(g)(1)(B), because it is intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease, and/or under section 201(g)(1)(C) of the FD&C Act, 21 U.S.C. 321(g)(1)(C), because it is intended to affect the structure or any function of the body.
Examples from the “NOWONDER™ Nasal Cleanser” product labeling, including your websites listed above, that provide evidence of the intended uses (as defined in 21 CFR 201.128) of the product as a drug include, but may not be limited to, the following:
“When people around you are sick, boost your body’s natural defenses with our Nasal Wellness Spray, powered by the wonder of Nitric Oxide. Nitric Oxide is naturally produced by your immune system and helps support your ability to fight germs that can cause the common cold, flu and other illnesses.” [from your product website]
“Powered by the Wonder of Nitric Oxide…Nitric Oxide safely and effectively improves your ability to fight common disease-causing germs and pathogens.” [from your product website]
“The Wonder of Nitric Oxide…Clinically proven to safely and effectively kill viruses and bacteria…Nitric oxide is a powerful, naturally occurring molecule that plays a critical role in supporting your immune defense and promoting overall health. Its antiviral and antimicrobial properties help protect against common infections and illnesses.” [from your product website]
“Effective…Clinical studies demonstrate that nitric oxide inhibits the replication of harmful viruses, including influenza and SARS-CoV-2, showcasing its powerful antiviral capabilities.” [from your product website]
“Effective cleansing whenever exposed to harmful elements such as bacteria, viruses…” [from your product label]
Your “NOWONDER™ Nasal Cleanser” drug product is not generally recognized as safe and effective (GRASE) 1 for use under the conditions prescribed, recommended, or suggested in its labeling and is therefore a “new drug” under section 201(p) of the FD&C Act, 21 U.S.C. 321(p). With certain exceptions not applicable here, a new drug may not be introduced or delivered for introduction into interstate commerce without an approved application from FDA in effect, as described in section 505(a) of the FD&C Act, 21 U.S.C. 355(a). No FDA-approved applications pursuant to section 505 of the FD&C Act, 21 U.S.C. 355, are in effect for this drug product. Accordingly, “NOWONDER™ Nasal Cleanser” is a new drug in violation of section 505(a) of the FD&C Act, 21 U.S.C. 355(a). The introduction or delivery for introduction of such a product into interstate commerce violates section 301(d) of the FD&C Act, 21 U.S.C. 331(d).
Conclusion
This letter is not intended to be an all-inclusive statement of violations that may exist in connection with your products. You are responsible for investigating and determining the causes of any violations and for preventing their recurrence or the occurrence of other violations. It is your responsibility to ensure that your firm complies with all requirements of federal law, including FDA regulations.
This letter notifies you of our concerns and provides you an opportunity to address them. Failure to adequately address this matter may result in legal action including, without limitation, seizure and injunction.
Please notify FDA in writing, within 15 working days of receipt of this letter, of the specific steps you have taken to correct any violations. Include an explanation of each step being taken to prevent the recurrence of violations, as well as copies of related documentation. If you believe that your products are not in violation of the FD&C Act, include your reasoning and any supporting information for our consideration. If you cannot complete corrective action within 15 working days, state the reason for the delay and the time within which you will complete the correction. Your response should be sent to U.S. Food and Drug Administration, CDER/OC/Office of Unapproved Drugs and Labeling Compliance by email to FDAAdvisory@fda.hhs.gov.
