Amnesic drugs are often given to patients in induced comas for medical treatment

My father in law in the early 2000s was put into an induced coma and put on life support in and ICU at a prestigious hospital in California. He was kept alive for 2 weeks while they figured out a way to deal with Staph and yeast in his blood. A specialist figured out a way to get rid of both within two weeks of this induced coma and before they woke him up they gave him an Amnesic drug so he would forget his hallucinations while in an induced coma for those 2 weeks time so he wouldn't have a psychotic episode when he woke up.

So, this is routinely done when a patient can afford to be put into an induced coma here in the U.S. since at the very least the early 2000s.
