yes. Mom was put on 30 mg daily of Xarelto. it made her dizzy tired and disoriented. she is 86 and had a kidney infection just previous to being put on Zarelto. She was flat on her back for about a month until doseage was reduced to 20 mg and then poof she was up walking around and get s better daily. now on 15 mg. Is it possible 30 mg was to much for her and how should have the doctors reacted. we tried to tell them it was too much and they wouldn t listen. Her kidney infection recurred at least twice during that 1st month
