Hello and welcome to HCM
What is the age of your sister?
Is she post-menopausal?Osteoporosis
is common among post menopausal women. It is due deficiency of estrogen
Deficiency of estrogens cause loss of bone density
Due to osteoporosis bone fractures
are common by trivial trauma.
Forsamax is a preparation used for osteoporosis.
So, it should not be stopped.
On the other hand long time use of steroids
cause decrease in bone density.
Steroids which you are using for SLE may be responsible for bone weakness.
Consult your treating doctor for adjustment of the dose to have minimal side effects.
However, forsamax should be continued.
Thanks and take care
