Overview

The Narcotics Monitoring System (NMS) has been developed to collect and store information on prescribing and dispensing activities for these medications. The information collected by the monitoring system will be used for improving prescribing and dispensing practices and to help reduce the use of prescription drugs for improper purposes.

Dispensers are required to submit dispensing information about all Monitored drugs to the NMS, and must do so in accordance with the Ontario Drug Programs Reference Manual (PDF).

Other initiatives underway include:

  • supporting education programs for health care providers in areas of the province where greater problems exist
  • Ontario’s Opioids Strategy
  • substance abuse treatment programs (including withdrawal management, community counselling and residential treatment and support services)

Monitored Drugs List

The Narcotics Safety and Awareness Act, 2010 and its requirements apply to a list of prescription medications called Monitored drugs. The Monitored Drugs List (MDL) provides a list of products that the Ministry of Health has selected for monitoring. This list will be used as a reference to determine if a submission to the Narcotics Monitoring System (NMS) is required for the product being dispensed.

Important: This list may not be comprehensive and may change as modifications are made to the federal Controlled Drugs and Substances Act and has been compiled in order to facilitate health care providers in identifying these medications
