Sir my aunt is 94 years old and has a sever case of dementia, her doctor prescribed Risperdone 3mg, there are very alarming warnings on all the info from drug store to mfg of the drug (do not use this drug to treat people with dementia or related problems, My doctor said he does this all the time. I am confused. Is there any special reason the doctor would give her this drug, with all the warnings against it, or have the warnings been lifted.
