BEG Nasal Spray is a compounded prescription spray designed to treat resistant bacterial infections in the sinuses, especially in patients with mold-related illness. “BEG” stands for its three key ingredients: Bactroban (mupirocin), EDTA, and Gentamicin. It breaks down biofilms and kills antibiotic-resistant bacteria, such as MARCoNS, that commonly colonize the nasal passages.

BEG Spray targets both the biofilm and the bacteria hiding inside it:

• EDTA dissolves the biofilm coating that protects the bacteria

• Mupirocin and Gentamicin penetrate and kill the exposed bacteria

This combination clears the sinuses, reduces inflammation, and helps restore a healthier nasal environment.

BEG Spray is recommended for patients who:

• Test positive for MARCoNS or other resistant nasal bacteria

• Have chronic sinus infections that don’t respond to standard treatments

• Are undergoing treatment for mold illness or CIRS and have persistent nasal symptoms

Testing with a nasal culture or PCR swab confirms if BEG Spray is appropriate.

Patients often report improvements such as:

• Reduced congestion, drainage, and sinus pressure

• Better breathing and improved sense of smell

• Reduced brain fog, fatigue, and headaches

• More effective progress with other mold detox treatments

Typical use is 2 to 3 sprays per nostril, twice daily, for 4–8 weeks, but your provider will personalize your plan. To maximize effectiveness:

• Blow your nose before use

• Aim the spray slightly outward toward your ear

• Avoid sniffing hard immediately after spraying

Mild burning or a bitter taste is normal. Saline rinses can help if irritation occurs.

Yes. Because it’s applied locally, absorption into the bloodstream is minimal. Side effects are usually mild and include temporary nasal irritation, dryness, or a slight nosebleed. Serious reactions are rare but monitored during treatment.

• BEG Spray focuses on bacterial infections like MARCoNS.

Silver/EDTA + Itraconazole Spray treats both fungal and bacterial colonization.
Your provider will choose the most effective option—or sometimes a sequence of both—based on your test results.

Some improvement is usually noticed within 1–2 weeks, but full eradication typically requires the full 4–8 week course. Consistency is key to preventing recurrence.

Yes. BEG Spray is custom-compounded and only available by prescription. Mobile Care Health handles your prescription and coordinates direct delivery through a trusted pharmacy.

After completing BEG therapy, most patients experience:

• Clearer nasal breathing

• Less congestion and drainage

• Reduced systemic inflammation and brain fog

• Better response to other mold treatments

A follow-up nasal culture is often performed to confirm MARCoNS has been eradicated.
