Can Lanfil DX cause diarrhea?
Yes, Lanfil DX may cause diarrhea as a side effect in some people. This is usually not bothersome, but if you experience persistent watery stools that do not go away, along with stomach cramps and fever, get medical help immediately. These symptoms are most likely because of the overgrowth of harmful bacteria called C. difficile and the diarrhea is known as Clostridium difficile–associated diarrhea (CDAD). Use of Lanfil DX lowers the natural stomach acid which normally helps to kill bacteria and this can cause this uncontrollable diarrhea associated with stomach cramps and fever.
