How long should I take Metronidazole for one course of treatment?

Metronidazole is generally considered for its anti-inflammatory effects, and the usual treatment course is 7 days. The specific duration of use depends on the situation. Metronidazole is used for the prevention and treatment of infections caused by anaerobic bacteria, such as respiratory, digestive, abdominal, and pelvic infections, infections of the skin and soft tissue, bone and bone joints, as well as endocarditis, sepsis, and meningitis caused by Bacteroides fragilis. It is also widely used in the prevention and treatment of oral anaerobic infections.

The dosage and administration of metronidazole tablets are as follows:

1. Common adult dosage:

① For intestinal amebiasis, the dose is 0.4-0.6g (2-3 tablets) three times a day for a course of 7 days. For extra-intestinal amebiasis, the dose is 0.6-0.8g (3-4 tablets) three times a day for a course of 20 days.

② For giardiasis, the dose is 0.4g (2 tablets) three times a day for a course of 5-10 days.

③ For dracunculiasis, the dose is 0.2g (1 tablet) three times a day for a course of 7 days.

2. Common pediatric dosage:

① For amebiasis, the daily dose is 30-50mg/kg of body weight, administered orally three times a day, for a course of 10 days.

② For giardiasis, the daily dose is 15-25mg/kg of body weight, administered orally three times a day for 10 days. The dosage for the treatment of dracunculiasis, balantidiasis, and trichomoniasis is the same as for giardiasis.

③ For anaerobic infections, the daily oral dose is 20-50mg/kg of body weight.
