Indications
Metronidazol is prescribed:

  • with trichomoniasis with clinical manifestations, if the presence of Trichomonas was confirmed by appropriate laboratory tests;
  • for the treatment of a sexual partner with an asymptomatic course of trichomoniasis (T.vaginalis) or if the pathogen is not isolated;
  • with asymptomatic trichomoniasis (cervicitis, endocervicitis, cervical erosion);
  • with amoebic dysentery (acute amebiasis), liver abscess provoked by amoebae;
  • with anaerobic bacterial infection (intra-abdominal abscess, peritonitis, liver abscess provoked by Bacteroides);
  • with gynecological infections (tubo-ovarian abscess, endometritis, endomyometritis, infection during gynecological operations), provoked by Bacteroides, Clostridium, Peptococcusniger, Peptostreptococcus;
  • for skin infections caused by Bacteroides, Peptococcusniger, Clostridium, Peptostreptococcus, Fusobacterium;
  • with infections of the lower respiratory tract (pneumonia, empyema, lung abscess) provoked by Bacteroides;
  • for infections of joints, bones caused by Bacteroides species;
  • with bacterial septicemia caused by Bacteroides, Clostridium;
  • with infections of the nervous system (meningitis, brain abscess), provoked by Bacteroides;
  • with endocarditis – inflammation of the inner wall of the heart, provoked by Bacteroides.

Contraindications:

  • in case of allergy to components (active or auxiliary);
  • with leukopenia;
  • with organic (non-infectious) changes in the brain (including epilepsy);

Method of application and dosage
Metronidazol should be administered intravenously only at a rate of 5 ml / min.
Pre- and postoperative prevention of infections: mainly in abdominal (especially colorectal) and gynecological surgery:

  • Adults: 500 mg immediately before surgery, complete the injection approximately 1 hour before surgery. Re-enter the dose every 8 hours.
  • Children:
    Children <12 years: a single dose of 20-30 mg / kg, the injection should be completed approximately 1 hour before surgery.
    Newborns with gestational age <40 weeks: 10 mg / kg body weight once before surgery.

Anaerobic infections. The duration of treatment depends on its effectiveness. In most cases, a seven-day course will suffice. In the presence of clinical indications (eg, eradication of infection from organs inaccessible to drainage, with a tendency to endogenous contamination by aerobic pathogens from the intestine, oropharynx or genitals), treatment can be continued.
Treatment of established anaerobic infections:

  • Adults: 500 mg every 8 hours.
  • Children:
    Children aged 8 weeks to 12 years: the usual daily dose is 20-30 mg / kg / day once or 7.5 mg / kg every 8 hours. The daily dose can 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 once daily or 7.5 mg / kg every 12 hours. Metronidazole may accumulate in infants <40 weeks of gestation during the first week of life, so serum concentrations of metronidazole should be monitored after a few days of treatment.

Bacterial vaginosis:
Adolescents: 400 mg twice daily for 5-7 days or 2000 mg once.

Urogenital trichomoniasis:

  • Adults and adolescents: 2000 mg once or 200 mg three times a day for 7 days, or 400 mg twice a day for 5-7 days.
