This is a two-part prescription nasal therapy to treat mold-related sinus issues, such as MARCoNS and chronic fungal sinusitis. The silver spray contains silver hydrosol, a potent antimicrobial; the other contains EDTA and itraconazole. Together, they help clear resistant bacteria and fungi from the sinuses.

The sprays work together to fight stubborn infections:

• Silver – acts as a broad-spectrum antimicrobial, helping to kill bacteria that contribute to chronic sinus infections. 
• Itraconazole – a potent antifungal that targets mold and yeast colonies deep in the sinus passages, reducing fungal load and inflammation. 
• EDTA – a biofilm disruptor that breaks down the protective barrier microbes build, allowing the silver and itraconazole to penetrate and fully eliminate hidden bacteria and fungi. 

This combination helps relieve congestion, drainage, sinus pressure, fatigue, and brain fog often linked to mold exposure.

Patients with mold illness, chronic sinus infections, or positive MARCoNS tests.

Your provider will give you personalized instructions, but in most cases, both sprays are used 2–3 times daily. The EDTA + Itraconazole spray is applied first, followed by the Silver spray 15–30 minutes later. The 15-30 minutes in between sprays is important to allow the EDTA to absorb, to reduce the risk of EDTA deactivating the Silver. A typical treatment course lasts 4–8 weeks, and consistent, timely use is essential for best results.

Yes. We only use a highly purified professional-grade silver hydrosol that is known for its exceptional purity and particle quality, meaning it delivers effective antimicrobial support with minimal additives and virtually no contaminants. This ensures you’re getting a clean, safe, and reliable formulation designed specifically for medical use. The EDTA + Itraconazole spray is a custom-compounded prescription designed to work primarily at the site of infection in the sinuses, with minimal absorption into the rest of the body, making it both effective and well-tolerated. Providers review your history to ensure it’s safe before prescribing.

MARCoNS (Multiple Antibiotic Resistant Coagulase-Negative Staph) is a resistant nasal bacteria often found in patients with toxic mold illness. It’s linked to conditions like chronic fatigue, fibromyalgia, and chronic sinusitis. These bacteria release toxins that trigger inflammation and disrupt the immune system, and many colonies form biofilms that shield them, making treatment more challenging.

Yes. This is a custom-compounded medication prescribed after a consultation to ensure it’s the right treatment for you.

Yes, but your provider will guide you on timing and compatibility. Sometimes it’s paired with systemic mold treatments or used sequentially with other nasal sprays like BEG spray.

If you have mold exposure, chronic sinus issues, or a positive MARCoNS test, this therapy may help. A consultation with your Mobile Care Health provider will determine if it’s a good fit.
