Hi, Does she have fever? Is the stool blood stained? Loose stools are most commonly caused by viruses, and need only rehydrating fluids like ORS, zinc supplementation and a probiotic. Antibiotics are not needed. Only a minor fraction is caused by bacteria/amoeba (dysentery). Here, child may have fever, the stool can be blood stained or with mucus, and there can be pain during defecation. This needs antibiotic treatment. But Ornof is a combination of two antibiotics, which is not recommended as first line treatment. For dysentery, I usually gives antibiotics like cefixime, along with above said supportive measures. For cases not responding, a stool microscopy can help to detect amoebic dysentery, that can be treated with drugs like metronidazol. It is better to discuss with your pediatrician before starting antibiotics. Meanwhile give her frequent sips of oral fluids like ORS to prevent dehydration. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Muhammed Aslam T. K., Pediatrician
