... was told over the phone "haldor" is what I was told. Question-my father has dementia, thought to be caused by drinking. He has been holding his pills in his cheek so they put him on liquid. I read something here that said haldol should not be used to treat dementia. Is this true or does anyoen else have a dementia patient/relative on this drug? His behavior is worse now. He is becoming increasing violent, and I think its the meds, not his mind. Thoughts and/or help PLEASE!
