My Father's Been On Eliquis For Four Or Five Months....he

my father's been on eliquis for four or five months....he wakes up and goes to the couch to lay down. he's never been a sleeper. Granted, at 87, maybe he's tired, but I wonder if it's a side effect. He sits on the couch and more or less leans over into a laying down position. I've never seen him like this. I don't know why you need my email. I'm just asking a question now here....
