  • The prevention of post-operative infections caused by anaerobic bacteria particularly species of bacteroides and anaerobic streptococci.

Adults and Children over 10 years only for:

  • Bacterial vaginosis (also known as non-specific vaginitis, anaerobic vaginitis or Gardnerella vaginitis).
  • Acute dental infections (e.g. acute pericoronitis and acute apical infections).

4.2. Posology and method of administration

Posology

A: Prophylaxis: against anaerobic infection-chiefly in the context of abdominal (especially colorectal) and gynaecological surgery.

Dosage: 400 mg at 8 hourly intervals during the 24 hours preceding the operation followed by postoperative intravenous or rectal administration until the patient is able to take Metronidazole Oral Suspension by mouth.

Children <12 years: 20 - 30 mg/kg as a single dose given 1 - 2 hours before surgery.

Newborns with a gestation age <40 weeks: 10 mg/kg body weight as a single dose before operation.

Elderly: Caution is advised in the elderly, particularly at high doses, although there is limited information available on modification of drug.

Anaerobic infections: The duration of a course of Metronidazole treatment is about 7 days but it will depend upon the seriousness of the patient's condition as assessed clinically and bacteriologically.

B: Treatment of established anaerobic infection:

800 mg followed by 400mg at 8 hourly intervals.

Children >8 weeks to 12 years of age: The usual daily dose is 20 - 30 mg/kg/day as a single dose or divided into 7.5 mg/kg every 8 hours. The daily dose may be increased to 40 mg/kg, depending on the severity of the infection. The duration of treatment is usually 7 days.

Children <8 weeks of age: 15 mg/kg as a single dose daily or divided into 7.5 mg/kg every 12 hours.

In newborns with a gestation age <40 weeks, accumulation of metronidazole can occur during the first week of life, which is why the concentrations of metronidazole in serum should preferably be monitored after a few days therapy.

C: Treatment of Protozoal and Other Infections:
