The website listed below shows all the active and inactive ingredients for all prescription an non-prescription medicines registered with the FDA. Just type in the EXACT name of the medicine and hit enter. It will pop up with a list if manufacturers to choose from. Click on your manu and and all pertanent medical info will show up. The last item in the list is 'ingredients'. Click on that and it will display all ingredients in that med. I have been working on my meds and have found several which contain laxatives, plastics, and other articles of concern. I am in the process of switching these meds out with other less threatening meds.
