@trinhttt most people on aromatase inhibitors like anastrazole seem to go on zoledronic acid, either Reclast or Zometa. They help with osteoporosis and also are said to have some protective effect in terms of bone cancer, or help with treatment. I personally consulted an endocrinologist. If you can, that is always helpful. But if there is a long wait maybe you could follow the oncologist's suggestions while you wait for endo.

The advice we all get is to hydrate really well day before, day of, day after- or even get IV hydration. And request a longer duration for the infusion, like an hour. The first time can bring a fluish reaction but after that it tends not to happen. Good luck!
