1 interaction related to kefir
Antibiotics can kill the live bacteria and yeast in kefir if both are taken at the same time, and dairy calcium can bind certain antibiotics (tetracyclines, fluoroquinolones) and reduce their absorption. Spacing kefir a couple of hours away from each dose addresses both concerns. Note that the broader claim that kefir prevents antibiotic-associated diarrhea is not well supported: the one randomized trial of kefir itself found no benefit.
