Why doctors aim to curb 'rampant prescribing of opioids'

Use of prescription opioids in Canada has risen steadily over the past 20 years, with skyrocketing misuse, disorders and deaths, say experts who call for enforceable guidelines and a national strategy to address overprescribing.

In Monday’s the Canadian Medical Association Journal, Prof. Benedikt Fischer of the Centre for Addiction and Mental Health in Toronto and his co-authors say it’s late, but not too late, for Canada to reduce the toll of opioid overuse and abuse. 

National surveillance data is spotty, but surveys suggest that by 2010, more than 1 in 20 adults and as many as 1 in 6 adolescents were using prescription opioids for non-medical purposes.

At the same time, demand for prescription opioid-related addiction treatment has soared.

In 2012, several provinces pulled oxycodone from their drug formularies and prescribing shifted to other potent opioids, such as fentanyl and hydromorphone. 

Fischer and his team seek guidelines to prescribe opioids only in exceptional cases, with strict limits on dose and duration.

They’d also like to see real-time electronic prescription monitoring systems across the country. They want doctors and pharmacists to be required to consult these databases before prescribing or dispensing opioids.

Here are some other key moments in Canada’s recent history of prescription opioids:
