Hi Jane, I didn't actually switch, I started straight on Arimidex and I did have a bone density test to use as a baseline. I have osteoporosis and have an injection every 6 months.I also take Vitamin D and calcium tablets. I was very concerned about the possible side effects of Arimidex, but as with everything, guess we just have to weigh everything up and make these hard decisions. I was already getting hot flushes and these did intensify slightly on Arimidex. Apart from this and maybe a bit moody at times, I haven't suffered any short term hassles. Hope it goes well for you,
Hazel xx
