This product has also been used as a possibly effective aid in treating colic in babies, and in preventing diarrhea in children that can occur while taking antibiotics.

In adults, lactobacillus rhamnosus GG is possibly effective in preventing diarrhea during a hospital stay, while you are receiving chemotherapy, or during travel to foreign countries ("traveler's diarrhea").

Other conditions for which lactobacillus rhamnosus GG is possibly effective include treating irritable bowel syndrome, ulcerative colitis, or vaginal infections caused by bacteria. This product may also lower the risk of lung infections in children who attend daycare centers.

Lactobacillus rhamnosus GG has also been used to treat Crohn's disease, lactose intolerance, or vaginal yeast infections. However, research has shown that lactobacillus rhamnosus GG may not be effective in treating these conditions.

Other uses not proven with research have included treating cold sores, urinary tract infections, high cholesterol, indigestion, cold symptoms, and boosting the immune system.
