  • H. pylori associate peptic ulcer disease:
    500 mg, 3 times daily in combination with at least one other agent that has activity against H. pylori (e.g. bismuth subsalicylate, amoxicillin...) for 1 - 2 weeks.
  • Hepatic impairment:
    Since metronidazole is mainly metabolised by hepatic oxidation, accumulation of metronidazole and its metabolites is likely in patients with severely impaired hepatic function. Metronidazole should therefore be given with caution and at reduced doses to patients with severe hepatic impairment, and especially hepatic encephalopathy when adverse effects of metronidazole can add to the symptoms of the disease. One-third of the usual daily dose may be given once daily in these patients. For patients with lesser degrees of hepatic impairment, pharmacokinetic studies have not produced consistent results and no recommendations about dosage reduction.
  • Renal impairment:
    The elimination of metronidazole is largely unchanged in patients with renal impairment, although metabolites may accumulate in patients with end-stage renal disease on dialysis. Dosage reductions are therefore not usually recommended for patients with renal impairment although, since both metronidazole and its metabolites are removed by haemodialysis, doses need to be given immediately after haemodialysis.

Or as prescribed by physicians.

  • Patients with known hypersensitivity to metronidazole or other nitroimidazole derivatives or any ingredient of the drug.
  • The first trimester of pregnancy.


  • The adverse effects of metronidazole are generally dose-related.

Most common:

  • Nausea, vomiting, anorexia, abdominal pain, diarrhoea and unpleasant metallic taste.

Less common:

  • Leucopenia.


  • Agranulocytosis; epileptiform seizures, peripheral neuropathy, headache; erythema multiforme, skin rash, pruritus; darkening of the urine.


  • Metronidazole appears to inhibit alcohol dehydrogenase and other alcohol oxidizing enzymes. Mild disulfiram - like reactions including flushing, headache, nausea, vomiting, abdominal cramps, and sweating.
  • Clinical and laboratory monitoring is advised if treatment exceeds 10 days.
  • Metronidazole should be used with caution and in reduced dosage in patients with severe hepatic impairment. Plasma concentration metronidazole be monitored in patients with severe hepatic impairment.
  • Pregnancy: Metronidazole crosses the placental barrier and enters the fetal circulation rapidly.
    There are no adequate or well - control studies to date using metronidazole in pregnant women, and the drug should be used during pregnancy only when clearly needed.
    Pregnant patients should not be treated during the first trimester.
  • Lactation: Metronidazole is secreted in human milk in concentrations similar to those found in plasma.
    Because of the potential for tumorigenicity, shown for metronidazole in mouse and rat studies, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
  • Effects on ability to drive and use machines: Patients should be warned about the potential for drowsiness, dizziness, confusion, hallucinations, convulsions or transient visual disorders, and advised not to drive or operate machinery if these symptoms occur.
