My dad was given seroquel during his hospital admission. The doctor said "it will help him sleep" but it didn't. His sleep became more irregular. Now he is given Zapiz instead of seroquel and his condition has gotten worse! the doctor isn't interested to change the medicine even after complains but on the other hand, my dad has started hallucinating which wasn't this intense before. I'm at a loss for words. what should I do to help my dad?
