• Disrupts bacterial DNA strands and prevents replication
• Reduces inflammation caused by the infection
• Targets both protozoal and bacterial cells

• For trichomoniasis: Single 2-gram dose or divided doses
• For giardiasis or amebiasis: Flagyl 250-750 mg three times daily
• Children: Dose depends on body weight and condition
• Always take with food or a full glass of water to reduce stomach upset
