I am sorry to hear about your friend's replacement of hip. Unfortunately, if a person is on Pred. for long period of time, s/he is at risk of having osteoperosis. One prevention is to take calcium 1200 mg daily. There is also a medication called Acetenol which prevents osteoperosis as well. I have taken Pred for about 17-18 years, and so far I am luckily okay. If the dosage of Pred is high, the patient is also likely to be at risk.
I do not know how to advice about the finance. She may be able to talk to the hospital and see if there is any scheme that will help in her situations. I just know the US health system is pretty darn bad. When I was in the US, I always have to worry about how much I need to pay after the coverage from the insurance. I think more people will give you more advice later.
