The recommended Flagyl dosage for treating amebic dysentery is 750 mg three times daily. For amebic liver abscess, the suggested dosage is 250 to 500 mg three times daily. Treatment typically lasts 5 to 10 days. For trichomoniasis, your healthcare provider will recommend either a one-day or seven-day treatment plan. Flagyl dosing for the treatment of anaerobic infections is determined by weight.
The dose of Flagyl® (metronidazole) that your healthcare provider recommends will vary, depending on a number of factors, including:
- The particular Flagyl product
- Your weight
- The type of infection
- Other medical conditions you may have
- Other medications you may currently be taking.
As is always the case, do not adjust your dosage unless your healthcare provider specifically instructs you to do so.
There are two different standard dosing regimens for treating trichomoniasis (a sexually transmitted infection). A one-day treatment of Flagyl 2 grams in a single dose or two doses of 1 gram (both taken in one day) is a convenient option. A seven-day treatment of 250 mg three times daily (or 375 mg twice daily) can also be used and may be more effective than the one-day treatment.
For amebic dysentery, the recommended Flagyl dose is 750 mg three times a day for 5 to 10 days. For an amebic liver abscess, the recommended dosage is 250 to 500 mg three times daily for 5 to 10 days. For treating ameba infections in children, your child's healthcare provider will calculate an appropriate dose based on your child's weight.
