Flagyl is indicated in the prophylaxis and treatment of infections in which anaerobic bacteria have been identified or are suspected to be the cause. Flagyl is active against a wide range of pathogenic micro-organisms notably species of Bacteroides, Fusobacteria, Clostridia, Eubacteria, anaerobic cocci and Gardnerella vaginalis. It is also active against Trichomonas, Entamoeba histolytica, Giardia lamblia and Balantidium coli. Flagyl is indicated in adults and children for the following indications: 1. The prevention of post-operative infections due to anaerobic bacteria, particularly species of Bacteroides and anaerobic streptococci. 2. The treatment of septicaemia, bacteraemia, peritonitis, brain abscess, necrotising pneumonia, osteomyelitis, puerperal sepsis, pelvic abscess, pelvic cellulitis, and post-operative wound infections from which pathogenic anaerobes have been isolated. 3. Urogenital trichomoniasis in the female (trichomonal vaginitis) and in the male. 4. Bacterial vaginosis (also known as non-specific vaginitis, anaerobic vaginosis or Gardnerella vaginitis). 5. All forms of amoebiasis (intestinal and extra-intestinal disease and that of symptomless cyst passers). 6. Giardiasis. 7. Acute ulcerative gingivitis. 8. Anaerobically-infected leg ulcers and pressure sores. 9. Acute dental infections (e.g. acute pericoronitis and acute apical infections). Considerations should be given to official guidance on the appropriate use of antibacterial agents.
