The use of acidophilus in cultural and traditional settings may differ from concepts accepted by current Western medicine. When considering the use of herbal supplements, consultation with a primary health care professional is advisable. Additionally, consultation with a practitioner trained in the uses of herbal/health supplements may be beneficial, and coordination of treatment among all health care providers involved may be advantageous. Acidophilus is also called Lactobacillus acidophilus. Lactobacillus acidophilus is a bacteria that exists in the body and is important in the maintenance of the normal level and consistency of bacteria in the body. Acidophilus has been used to re-establish the normal consistency of bacteria in the gastrointestinal tract (stomach and intestines) and vagina. Acidophilus has been used in the treatment and/or prevention of vaginal yeast infections, yeast infections of the mouth, antibiotic-induced diarrhea, and urinary tract infections. Acidophilus has not been evaluated by the FDA for safety, effectiveness, or purity. All potential risks and/or advantages of acidophilus may not be known. Additionally, there are no regulated manufacturing standards in place for these compounds. There have been instances where herbal/health supplements have been sold which were contaminated with toxic metals or other drugs. Herbal/health supplements should be purchased from a reliable source to minimize the risk of contamination. Acidophilus may also have uses other than those listed in this product guide.
