When a two-year-old baby with enteritis has diarrhea, the medication recommended is generally determined by the cause of the enteritis. If it is bacterial enteritis caused by unclean diet, which is what we usually see as acute bacterial enteritis, then we should first take some antibiotics, such as cephalosporin III antibiotics, which can be taken orally, and at the same time, the symptoms of diarrhea can be treated with Similac (montelukast) to stop the diarrhea. But pay attention to the symptoms after the relief, for example, diarrhea reached 1-2 times a day can stop the drug, continued use of drugs can also lead to constipation, but also with some probiotic drugs to regulate the intestinal flora.
