I've heard from random podcasts (do your own research) you need to make sure you exercise, and perhaps eat high protein, while on drugs like this, otherwise you lose a ton of muscle mass. Could be deadly for seniors, where falls are a leading cause of death.

This is not to say the drug is bad, simply to encourage education so we dont trade one problem for another.
