Antidepressant Use The popularity of psychiatric medications has skyrocketed in recent years. A recent report from the Organisation for Economic Co-operation and Development (OECD) reveals that antidepressant use among Canadians is among the highest in the world (the red “OECD23” bars give the average of the 23 countries in the graph). Although prior data was not available for a few countries including Canada, the OECD survey revealed that antidepressant consumption has increased dramatically since 2000 in every other country surveyed, doubling in Australia for example, and increasing four times in the Czech Republic. In Iceland, 30 percent of women over the age of 65 are now being treated with an antidepressant (OECD, 2013)
