I took one lactaid, for the first time for lactose intolerance. three hours later began vomiting and had severe diarrhea. However, diarrhea was nothing but mucus, like egg whites; and colorless. Can find nothing else different. Wondered about drug interaction, as I take numerous meds for various issues, like high blood pressure, hypo thyroid, cholesterol, ulsers, etc.. Is it a likelyanwer?
