BEG Nasal Spray
BEG is a compounded nasal spray that combines Bactroban (mupirocin), EDTA, and gentamicin. It is applied in the nasal passages to target antibiotic-resistant, biofilm-forming bacteria — most notably MARCoNS (multiply antibiotic-resistant coagulase-negative staph). In chronic mold and inflammatory illness, these deep-nasal colonizers can shelter inside a protective biofilm and keep the immune system stirred up, which is thought to interfere with recovery. The EDTA in the spray helps break down that biofilm so the antimicrobials can reach the bacteria. It is compounded and prescribed on a case-by-case basis, usually after appropriate nasal testing.
