The WSIB drug benefit program pays for the costs of prescription drugs required for allowed work-related injury and illness, and the professional pharmacist fees, according to the set fee schedule. Canadian pharmacies can electronically bill prescriptions allowing for real-time confirmation of coverage.  

Read more about filling prescriptions at the pharmacy.

A drug formulary is a list of medications potentially paid by an insurer. An injured and ill person may have access to different drug formularies depending on the nature of their work-related injury. See our drug formularies for more information. 

The WSIB collaborates with the Drug Advisory Committee (DAC) on issues relating to our drug benefit program.  To learn more, view the Drug Advisory Committee (DAC) Terms of Reference and member list. 

The DAC follows an evidence-based approach and considers external, independent reviews to make its recommendations on formulary drug listing decisions. 

Use our drug benefit program formulary search tool to learn more about the drugs that we cover. 

• The search provides information on medications that have general benefit and prior authorization (PA) status. If the medication cannot be found in the search tool, it is not listed on WSIB formularies. Please see prior authorization for coverage criteria. Please see non-formulary drugs for how to request exceptional use. For narcotic (opioid) medication coverage, please read about our approach to opioid treatment. 

For narcotic (opioid) medication coverage, please consult opioids at the WSIB.
