Everyone is different - that said, I was on similar meds last couple of times I had a cold. In one case it was gone after 5 days, no big deal. In the other case it lasted longer and turned into bronchitis without me noticing.
My advice? Keep a bit more of a watch on it that you would have done pre-lupus. If it seems to be worsening or lasting more than 5 days please see your doctor ASAP. Things do slip in under the radar (unannounced) when we have these meds on board.
It also matters what your general health level is -- if you have a lot of lupus activity get thee to a Dr sooner, but if you are generally in good shape the dire warnings may be a bit of overkill.
Hope that makes sense -- the warnings are real, but general health tells you just how watchful you need to be....
