Generally speaking, there are few to no side effects from the ingredients used in the protocol but I’ll break it down into its components. Olive oil and fish are capable of occasionally causing nausea if too much is given at one time. Both of these oils can sometimes cause diarrhea and maybe a slight worsening of behavior as well. If this occurs, it is a sign that you most likely still have some degree of bacterial overgrowth and I’ll recommend to my patients to either switch from inulin to rifaximin or increase their use of rifaximin.nnInulin has been proven to be very safe in even neonates but in some children, inulin in doses greater than 1/4 or 1/2 a teaspoon might trigger an increase of hyperactivity, anxiousness and even trigger a little aggression. These issues will quickly resolve simply by lowering the dose.nnIn my experience working with children, rifaximin has little to no side effects since it does not enter the bloodstream. In adults, there have been reported cases of enterocolitis but I have never seen this occur in children.
