there is a website where you can check potential drug interactions....it wont give you a complete list you'd have to check a PDR for that but here it is just in case you want it... since youre taking so many different things. (i cant take dextromethorphan because i also take zoloft and it could cause serotonin syndrome. dextromethorphan also can cause a bad reaction with MAOI's and can cause liver damage if taken with Serzone or Desyrel.... but you wont find that info at drug digest)
