About the Recalled Product
The recall covers ReBoost Nasal Spray, a homeopathic spray marketed for temporary relief of nasal congestion, sinus pressure, postnasal drip, sneezing, and runny nose, sold in 20 mL (0.68 fl. oz.) white and yellow carton packaging with NDC 62795-4005-9 and UPC 787647101863. Only Lot No. 224268 (expiration 12/2027) is included; the product was sold nationwide at CVS, Walmart, Amazon, and medinatura.com.
Latest Updates
The FDA assigned Class I Recall No. D-0288-2026 to ReBoost Nasal Spray on December 12, 2025, covering Lot No. 224268 distributed nationwide through retail stores and online, citing microbial contamination — including yeast, mold, and Achromobacter at levels above specifications — with a reasonable probability of life-threatening infections in immunocompromised users [1][2]. On December 16, 2025, MediNatura expanded the action to also include ClearLife Allergy Nasal Spray after further internal investigation linked the same contamination concern to that product, with no adverse events reported for either product as of the recall date [3].
The Contamination: Achromobacter, Yeast, and Mold
Laboratory testing identified three categories of microbial contamination in the recalled ReBoost lot at levels above specification: Achromobacter, a gram-negative opportunistic bacterium; yeast; and mold. Achromobacter is rarely a threat to healthy individuals but can cause severe, treatment-resistant infections in people with compromised immune systems — including patients receiving chemotherapy, organ transplant recipients, individuals with HIV/AIDS, and those on long-term corticosteroid therapy.
Nasal sprays are administered directly onto the nasal mucosa, a highly vascularized surface with direct pathways to the sinuses, throat, and lungs, bypassing the skin’s protective barrier and delivering a contaminating organism in close proximity to the respiratory tract. For an immunocompromised user, introducing Achromobacter through this route creates a meaningful risk of local sinus infection, respiratory infection, or systemic bacteremia that can progress rapidly and prove difficult to treat with standard antibiotics.
What Is a Class I Recall?
The FDA reserves Class I status for situations where there is a reasonable probability that use of the recalled product will cause serious adverse health consequences or death — it is the highest urgency level the agency assigns, above Class II and Class III. A Class I designation for a consumer nasal spray signals that federal regulators determined the contamination posed an immediate and genuine public health risk, not a minor technical deviation.
Who Was at Risk
ReBoost Nasal Spray is an over-the-counter homeopathic product available without a prescription, meaning it was used by consumers who had no physician’s warning about contamination risk and no way to identify a compromised lot by looking at or smelling the product. The FDA’s warning specifically identified immunocompromised individuals — a broad category that includes millions of Americans undergoing cancer treatment, organ transplant patients, and those with autoimmune conditions — as the population facing life-threatening risk from continued use.
Consumers who purchased Lot No. 224268 (expiration 12/2027) while the product was on the market for the two years before the recall are urged to check their supplies, as the December 2027 expiration date means the recalled lot remained within its labeled shelf life at the time of the recall and may still be in consumers’ medicine cabinets.
Can I File a Lawsuit?
If you experienced a sinus infection, fungal infection, respiratory infection, or other serious health event after using ReBoost Nasal Spray from Lot No. 224268, you may have a product liability claim against MediNatura New Mexico for distributing a contaminated drug product. Contact a product liability attorney as soon as possible, as state filing deadlines apply.
