the dosage is whatever the bottle / package says or your doctor says. As far as I know they can be taken daily ongoing without needing a break. You could set your gut into a little haywire if you stop because it is used to the probiotic. But I would ask your doctor this question.Probiotics seem to help me a lot.....but how long can we take them and at what dosage?Do we take them for so long....take a break and then begin to take them again?Thanks!Del
