You take probiotics,in the form of the probiotic supplement itself or plain old yogurt,as a way of replenishing the normal flora/bacteria in your intestine. Often when a person takes antibiotics,the drug itself is not causing the side effect of nausea,diarrhea,etc - rather,the good bacteria/flora are killed along with the bad,and you develop a separate issue called C.Difficile. This can be dangerous,and is normally kept at bay by the good guys in the intestinal tract. Eat yogurt,couple times a day,and all will be well.
