I am currently taking prednisone, Plaguenil, Coumadin and Cymbalta. Just had my first infusion of Benlysta a week ago, Wednesday. Had no major reaction, in fact I had tons of energy until yesterday, Saturday afternoon. Major fatigue set in. Had to sleep the rest of the day. I have the anti-cardiolipins symdrome. How long can it take to see results from Benlysta?
