Hi...I have been taking Letrozole for 6 months and the side effects with this prescription is running nose, sneezing, hot flashes and freezing all the time. I'm very active running, weight lifting, spinning, Bootcamp,yogi class and also eating clean. Very little to no joint pain due these intense type of excerise, keeps you from losing bone mask. However the memory delay hot flashes , cold flashes and thinning hair. I think you are right about the different brands of prescription and each having different side effects. During my Chemo treatment I had running nose and sneezing just terrible and bone pain. I had to walk everyday just so the pain wasn't bad and finally I started back running and weight lifting which help stop the pain altogether. I will call my doctor because these new pills is effecting my immune system. Thank you for all your help. May God continue to bring good health in your life😘
