Danazol takes several months to work, so I am not sure why the doctor took your wife off of it so quickly. There is a high success rate with Danazol as a first-line monotherapy treatment for SAA. I believe the success rate is even higher in women with SAA. All that said, I am not your doctor, and don't know his or her reasons for doing so.
Could it be the Promacta with the Danazol?
I surely hope things get better for your wife. She's already off blood transfusions, which is amazing! Congratulations!
By the way, Danazol is lower dosages does not usually cause terrible side effects.
