Doc,safe to take a pill of probiotic everyday?can it cause hives,allergies and any other side effects? i had high ige .any relation to probiotics ?

Usually: Most people can tolerate probiotics but extremely high doses can cause gastrointestinal upset. I am not aware of any link to hives or allergic diseases. In fact, there are studies showing that probiotics may lower the chance of developing eczema for infants. Do note that not all probiotics are created equal and different strains may be needed for different folks- thus no universal good guy.
