3-Week Antibiotic Treatment Regimens
For a 3-week treatment course, the most appropriate antibiotic regimen depends on the specific infection being treated, but based on established guidelines, common 3-week protocols include ampicillin (1 g/L) + metronidazole (1 g/L) + neomycin sulfate (1 g/L) + vancomycin (0.5 g/L) for infectious diseases, or vancomycin (0.5 g/L) + ampicillin (1 g/L) + kanamycin (1 g/L) + metronidazole (1 g/L) for immune system-related infections. 1
Infection-Specific 3-Week Regimens
Infectious Diseases
For infectious disease indications requiring 3-week therapy, the evidence supports several antibiotic cocktail options 1:
- Standard quadruple therapy: Ampicillin (1 g/L) + metronidazole (1 g/L) + neomycin sulfate (1 g/L) + vancomycin (0.5 g/L) 1
- Alternative with aminoglycosides: Ampicillin (1 g/L) + neomycin (1 g/L) + streptomycin (1 g/L) + kanamycin (1 g/L), with or without antifungal coverage 1
Immune System Disorders
For immune-related conditions requiring 3-week treatment 1:
- Primary regimen: Vancomycin (0.5 g/L) + ampicillin (1 g/L) + kanamycin (1
