Hi, I am having trouble sleeping and I had a friend recommend Melatonin to help but I take a number of medications daily, plaquenil, prednisone, monocor, HCT, losec, domperidone, citalopram, serc, crestor, slow k, folic acid, and vitamin d. just wondering if any of my meds will interact with the melatonin, I currently don t have a family doctor.
