Flagyl 400 mg – High-Dose Metronidazole Tablet for Aggressive Infections
Flagyl 400 mg is a potent antibiotic and antiprotozoal medication containing a high dose of metronidazole. It is prescribed for more severe or persistent bacterial and parasitic infections. As part of the nitroimidazole class, Flagyl 400 mg effectively treats conditions such as trichomoniasis, amoebiasis, giardiasis, bacterial vaginosis, anaerobic infections, and post-surgical prophylaxis.
Which Conditions Require Flagyl 400 mg?
- Extra-intestinal amoebiasis (liver abscesses, systemic infections)
- Giardiasis in adults with resistant or severe symptoms
- Trichomoniasis cases requiring higher dosing
- Severe anaerobic bacterial infections (abscesses, periodontal disease)
- Post-operative prophylaxis, especially colorectal surgeries
Mechanism of Action
Metronidazole is taken up by anaerobic bacteria and protozoa, where it converts into an active form that disrupts DNA integrity, leading to microbial death. The 400 mg dosage ensures sustained high levels in the bloodstream and tissues to combat stubborn infections.
