It is not advised to give metronidazole (flagyl) in water as it is very bitter tasting and they probably won't drink it. You can get metronidazole OTC as Fish-Zole (250 mg) or Meditrich (100mg). The recommended dose is no less than 30mg/kg by mouth once a day for five days, but many people give more and some give it twice a day.
