Treatment of Anaerobic Infections
The recommended dosage schedule for adults is:
||15 mg/kg infused over one hour (approximately 1 g for a 70-kg adult).
||7.5 mg/kg infused over one hour every six hours (approximately 500 mg for a 70-kg adult). The first maintenance dose should be instituted six hours following the initiation of the loading dose.
Parenteral therapy may be changed to oral metronidazole when conditions warrant, based upon the severity of the disease and the response of the patient to Metronidazole Injection, USP RTU treatment. The usual adult oral dosage is 7.5 mg/kg every six hours.
A maximum of 4 g should not be exceeded during a 24-hour period.
Patients with severe hepatic disease metabolize metronidazole slowly, with resultant accumulation of metronidazole and its metabolites in the plasma. Accordingly, for such patients, doses below those usually recommended should be administered cautiously. Close monitoring of plasma metronidazole levels3 and toxicity is recommended.
In patients receiving Metronidazole Injection, USP RTU in whom gastric secretions are continuously removed by nasogastric aspiration, sufficient metronidazole may be removed in the aspirate to cause a reduction in serum levels.
The dose of Metronidazole Injection, USP RTU should not be specifically reduced in anuric patients since accumulated metabolites may be rapidly removed by dialysis.
The usual duration of therapy is 7 to 10 days; however, infections of the bone and joint, lower respiratory tract and endocardium may require longer treatment.
For surgical prophylactic use, to prevent postoperative infection in contaminated or potentially contaminated colorectal surgery, the recommended dosage schedule for adults is:
- 15 mg/kg infused over 30 to 60 minutes and completed approximately one hour before surgery; followed by
- 7.5 mg/kg infused over 30 to 60 minutes at 6 and 12 hours after the initial dose.
It is important that (1) administration of the initial preoperative dose be completed approximately one hour before surgery so that adequate drug levels are present in the serum and tissues at the time of initial incision, and (2) Metronidazole Injection, USP RTU be administered, if necessary, at 6-hour intervals to maintain effective drug levels. Prophylactic use of Metronidazole Injection, USP RTU should be limited to the day of surgery only, following the above guidelines.

Additives should not be introduced into Metronidazole Injection, USP RTU. If used with a primary intravenous fluid system, the primary solution should be discontinued during metronidazole infusion.
