Hi newsereneme, If you go to www.drugs.com there is a place on that site to put in your medication profile and then will automatically cross-refference your meds. I did this and found that my belladonna for IBS has an interaction with Lexapro for depression. I now take them far enough apart so that they do not adversly effect each other. I found it a very valuable tool, it will even cross reference over the counter and naturals. I hope this is helpful for you it is a great site for cross interations. And as always speak to your doctor or pharmasist also. Good Luck vlbhopes you find the answers there. Hang in there, take care of yourself.
