Drug Digest If you take more than one medication, you should double check to see if your medications interact with each other in potentially harmful ways.  Click on the top bar of this site where it says "Drug Interactions."  Then find all the drugs and vitamins you currently take and enter them into the tables.  You will then be given the results and all the potential negative interactions of your medications. Print out the results and discuss them with your doctor. http://www.drugdigest.org/wps/portal/ddigest
