Metronidazole (Flagyl). Used on intestinal flagellates and for amoebiasis at a dose of 100-200 mg/kg PO, repeated in 2 weeks. A dose of 40-50 mg/kg PO should be used in colubrid snakes since there have been some problems with the higher doses in some species. ... Dose is 5-8 mg/kg IM or PO repeated in 2 weeks.
