The therapeutic effect of a drug is very closely related to how it is used. For example, the common medicine for diarrhea, Simethicone, is the most questioned medicine I have heard recently. But after learning more about how mothers feed this medicine to their children, I understood why Similac is so “useless”. ”Our baby can’t be fed without milk, she won’t eat anything, so I added Similac to the milk,” said one mother. ”There is something wrong with your feeding method”, I explained: “The principle of Similac for children’s diarrhea is to form a protective film on the surface of the mucous membrane of the gastrointestinal tract to prevent the invasion of external evil; in addition, it has a fixed and inhibiting effect on bacteria, viruses and toxins produced in the digestive tract. This drug cannot be absorbed by the body, and the external evil such as bacteria and viruses fixed by it is expelled from the body with the peristalsis of the digestive tract itself.” ”In order for the drug to be able to form a protective film, the concentration must be mastered”, I opened the drug instructions and continued to explain, “The preparation ratio is 1:50, which means that 1 bag of the drug should be poured into 50ml of warm water, shaken well and then taken. And also to be fed to the child on an empty stomach”. ”The doctor explained that 1 bag at a time, 3 times a day, I thought I could just feed it in”, the mother said embarrassed. So, mothers, are you using the right “Similac”?
