Flagyl 200 mg: Reliable Antibiotic for Bacterial & Parasitic Infections
Table of Contents
What is Flagyl 200 mg?
Flagyl 200 mg contains the active ingredient metronidazole, an antimicrobial medication effective against anaerobic bacteria and certain parasites. Developed initially for bacterial infections, it is now widely used to treat gastrointestinal, vaginal, skin, and dental infections.
How It Works
Metronidazole disrupts microbial DNA synthesis by entering bacterial and protozoal cells and forming toxic compounds that attack DNA strands. This action prevents cell replication and ultimately kills the microorganisms causing the infection.
Medical Uses
Flagyl 200 mg is prescribed for a variety of conditions, including:
- ✅ Bacterial vaginosis and pelvic inflammatory disease
- ✅ Giardiasis and amoebiasis
- ✅ Trichomoniasis
- ✅ Anaerobic bacterial infections (e.g., dental, intra-abdominal)
- ✅ Prevention of infection during colorectal surgery
Dosage & Administration
Dosage varies by infection type, often:
- Adults: 200–400 mg every 8 hours for 5–10 days
- Children: 30 mg/kg per day divided into 3 doses
