My dad is 90 yrs old, in hospital given a dose of dilaudid at 3PM and again at 3AM was completely out if it for almost 3 days. Looked like he was having terrors. Eyes open as wide as possible and mouth in screaming position.(not a sound came out) arms flailing..very scary. Not a wink of sleep the whole time. this was 9 days ago, just coming out of it now. Should a 90 yr old have been given anything this strong?
