Anxiety
"My mother has cancer. With that she has anxiety. The Dr prescribed her vistaril 25mg. Granted it kinda helps anxiety but it contributes to hallucinations. When I leave her off of it she has anxiety when she takes it, her dreams are vividly real. Weigh your options or decrease dosage but if a loved one is taking this medication before mental diagnosis try replacing or removing this drug for at least 48 hrs."
