Hello, I am presently taking femara (1 1/2 yrs into the therapy and 2 1/2 more years to go). I have developed arthritis in my thumb joint and wanted to take glucosamine chondroitin supplements. Will this interfere with my femara therapy? I live in Italy and the doctors do not believe in vitamins/supplements, etc. so no matter which doctor I ask they really don't answer since it's very different over here. I would appreciate if you could help me out with some information so that I can start taking the glucosamine. Thank you. Joan
