WM’s CsRx® Controlled Substance Disposal Service is designed to safely prevent diversion and ensure compliance when disposing of controlled substance waste.

Our service supports your organization’s diversion prevention efforts. Although additional measures throughout your facility are recommended, CsRx is a solution for safely disposing controlled substance wastage immediately after patient administration, to mitigate drug diversion and protect the environment.*
The Program Includes:
Staff training with instructions on proper and best practices
Lockable wall-mounted brackets and hardware installed by WM’s installation team
Containers prefilled with deactivating, deterring, and solidifying agents
Ongoing and proactive container management
Destruction of waste by incineration
*Only Health Canada classified controlled substances can be accepted in CsRx containers. CsRx Service is for controlled substances that have been dispensed to a patient at the registrant's location and need to be wasted at that location. CsRx is for controlled substance wastage only. It is not for the disposal of controlled substances brought in by patients or items that would be considered part of a facility’s inventory.
Helps Mitigate Drug Diversion and Reduce Risk
Deactivates controlled substance wastage
Deters ingestion of the contents
Solidification of waste for storage and transportation
Unlike other products on the market, CsRx offers the perfect combination of safety, protection, and value. There’s no cumbersome equipment required, nor are electrical or plumbing connections needed. The material is disposed of through incineration to mitigate the risk of pharmaceutical contamination in our waterways.
