pulmonary embolism
"In answer to change of health after going from 30mg a day to 20mg: I was diagnosed with a massive saddle PE on May 1, 2016 after having uncontrolled sweating with subsequent shortness of breath. 911 call, ER, BP 60/40 w/pulse 130-160. Doctor said surprised I made it to the hospital. Healthy, active 56yr old released after overnight stay with 6mos Xarelto therapy. Was fine with 21 day 15mg 2x day; 20 mg change made me feel like I was dying. Realized it was too much for my system at one time; cut the pill in half & took 1/2 2xday--still got my 20mg & felt good again. Finished with treatment for moment; since was unprovoked they've done extensive tests to find I have Factor 5. Waiting to see how 2.5mg Eliquis 2x dy 6mos works; just started."
