Safety
The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.
Allergies
Lactose-sensitive people may develop abdominal discomfort or other adverse effects from L. acidophilus -containing products, due to very small amounts of lactose left over from the manufacturing process. Avoid in patients with milk allergies.
Side Effects and Warnings
L. acidophilus is generally well tolerated with very few side effects.
Use with caution in infants, children, older patients, or patients with gastrointestinal disorders, short bowel syndrome, or high fever.
Avoid in patients with weakened immune systems or milk allergies.
Pregnancy and Breastfeeding
Lactobacillus GG has been used safely during pregnancy (2-4 weeks before delivery) and lactation (for up to six months). L. acidophilus has been studied in pregnant women for prevention of premature delivery.
