We are currently at a stable state of 0.5mg Sirolimus and 1mg Tacrolimus. These are both immunosuppressant drugs. Their doses are adjusted twice a week, after the Complete Blood Count lab work reveals the chemical make-up of Mama Pham's body. Too much of these drugs can compromise the health of the body's organs as well as suppress the immune system too much, preventing it from fighting lingering cancer cells and other infections. Not enough immunosuppressants can increase the risk of Graft vs. Host Disease (GVHD). The goal is to have the perfect amount each day to suppress the immune system enough to prevent GVHD, but still keep the body healthy and strong with the ability to fight the bad guys.
