Some medications take a while to build up in your system, so you may have to take them a few months before noticing side-effects like hair loss. (Thus "recent changes" might not
be the only way to get medication side-effects.)
Some people find Lupus itself causes hair loss.
I had some hair thinning (on my head) from the Cellcept I was taking for Lupus. I didn't notice any differences in underarm hair from either Lupus or Cellcept -- although honestly, if underarm and public hair thinned I might not have noticed it.
Maybe we could help you out more if you could post her medication list?
