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 a bacterial infectious enteritis due to unclean diet, which 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 use montelukast to stop diarrhea for the symptoms of diarrhea. But pay attention to the symptoms after the relief, for example, diarrhea reached 1-2 times a day can stop using montelukast, continued use of drugs can also lead to constipation, but also with some probiotic drugs for intestinal flora regulation.
