Anti-werewolf pep talk?

Unfortunately Prolia only on PBS if you have had a fracture already and gather very expensive if not . However there are bisphosphonate tablets you can take but need to be careful you stay upright for 30 minutes after taking to avoid an ulcer in gullet. Also regardless Prolia or bisphosphonate tablets serious dental can cause osteonecrosis of the jaw - eg root canals , extractions. Make sure you take good care of your teeth and they are sound before you start bisphosphonate or  Prolia. There are things you can do as you know to promote bone density like weight bearing exercise , Calcium/ Vit D tablets ( I take 2 Caltrate bone health daily). etc etc but whilst on arimidex hope you have regular bone density checks . Your medical oncologist should be monitoring this for you and providing guidance - diet and sunlight may not be enough on aromatase inhibitors I'd be talking to the onc who put you on arimidex who has specialist knowledge . There is an osteoporosis site online also I'd be looking at their suggestions  too- it all helps.
