All I can tell you is that within the past 3 months my gyno wanted to put me on hormone replacement therapy. I thought my rhuemy was going to have a stroke when I told her. She informed me that hormone therapy can cause a lupus patient to go into a severe flare. She also said that normally if a gyno wants to put a lupus patient on hormones the gyno and the rhuemy consult each other as to the dosage.
Hope this helps.
PS: I have switched gynos....evidently the 1st one wasn't listening to me when I told her about my other medical conditions.
