Does , Or Can,Eliquis Cause Extreme Weakness? My Husband Had

Does , or can,Eliquis cause extreme weakness? My husband had been on warfarin fir a long time, but was having TIA's,so dr. Prescribed an implant to detect AFib. That has been several weeks now with nothing detected. He seems to be getting weaker, having more trouble getting out of the recliner, which is a firm-type lift chair. What is your opinion?
