Many antibiotics cause diarrhea.
The diarrhea is usually mild and will not cause a child to become dehydrated or lose weight. The stools return to normal 1 or 2 days after the child finishes the antibiotic treatment. Your child does not need to stop taking the antibiotic. Your child's diet does not need to be changed, although you may wish to cut back on beans and apple, grape, pear, and peach juices. Your child can continue drinking cranberry juice and orange or other citrus juices.
