Medgyl IV Dosage/Direction for Use

Treatment: Adults and Children over 12 years: 100 mL by intravenous infusion eight hourly. The injection should be infused intravenously at the rate of 5 mL per minute, but maybe administered alone or concurrently but separately, with other bacteriological appropriate antibacterial agents in parenteral dosage forms. Oral medication with 400 mg three times daily should be substituted as soon as this becomes feasible. Treatment for seven days should be satisfactorily for most patients but depending upon clinical and bacteriological assessments, the physician might decide to prolong treatment, e.g. for the eradication of infection from sites which cannot be drained or are liable to endogenous recontamination by anaerobic pathogens from the gut, oropharynx or genital tract.
Children under 12 years: As for adults, but the single intravenous dose is based on 1.5 mL/kg body weight. (7.5 mg Metronidazole/kg body mass) and the oral dose of 7 mg/kg body mass.
Or as prescribed by the physician.
Adults and Children over 12 years: 100 mL by intravenous infusion immediately before, during or after an operation, followed by the same dose eight hourly until oral medication can be given to complete a seven-day course. In infants and other patients maintained on intravenous fluids metronidazole injection may be diluted with appropriate volumes of normal saline, dextro-saline, dextrose 5% or potassium chloride injections.
Or as prescribed by the physician.
