Also her mood and behavior have changed a lot in the past few weeks. The drug that concerns me the most is the simvastatin. At home I gave her very high dose omega 3 fish oil. And this kept her cholesterol down. My question is, can I tell the facility/doctor that I do not want her on the "statin" and substitute it with pharmaceutical grade fish oil? (Sometimes called esters Or omega 3, legally, as her daughter do I have the right to tell them to take her off that medication? I am mom's medical proxy. Her bill for medication for 4 weeks is $150.00. At home it was $50 for blood pressure meds. They also have her on high dose very strong anti-depressant (mirtazapine) if it works I don't have any issue with her taking it.
