My mom is 89 diagnosed with minor normal dementia then developed a blot clot...given xarelto....couple months later is now hallucinating. No other med changes for may years. Does take small amounts of Ativan for myoclonic tremors but has for 5 years with no issues. Takes Toprol, Lipitor, midodrine and a few others, but again has had all for many years without issues. Your thought please on the xarelto causing the hallucinations. They seemed to start overnight almost.
