The Health and Disability Commission has decided not to investigate Dunedin Hospital after claims patients were given Ketamine without consent.
The Commission received a complaint from a mental health trust, alleging the drug was trialled on depressed patients.
It is used by vets as a horse tranquiliser, and is rarely used to treat depression.
The hospital's Chief Medical Officer Dick Bunton says patients were asked for their permission first.
“Ketamine has been around for such a long, long time, that all of its effects are very well known. The issue here is not one of safety, but one of people becoming confused about what ‘off-label’ means”.
Dick Bunton says an off-label trial means the drug has been used and detailed in literature, but not properly trialled.
