“What is the best medicine for baby diarrhea?”

Baby diarrhea can be simple and also serious. It is not possible to answer this question without evaluation. Typically no medication nut evaluation and assessment are important.

There really is no safe medicine that you can give to a baby for diarrhea. If the diarrhea is from an infection you simply have to wait and let the baby's immune system fight off the disease and then the diarrhea will go away. This can sometimes take several weeks. If the diarrhea is due to something else like an allergic reaction then you may need to just try and change the baby's diet to see if that improves the diarrhea.
