If a child has enteritis, he or she can take montelukast. Especially in children with viral enteritis, the frequency of stools may increase significantly and the stools may be dilute and watery or even egg-like. At this time, children are at risk of dehydration and electrolyte disturbance. The timely administration of montelukast can help children’s stools become normal. For example, after children have loose stools, they will return to a thick stool after taking montelukast, which also has the effect of protecting the intestinal mucosa. Therefore, if children have enteritis, they can take montelukast. If the child has bacterial enteritis, it is necessary to take montelukast together with cephalosporin and other drugs.
