Hamilton Public Health Services is currently undertaking a comprehensive review and assessment of the naloxone data and reporting processes. At this time, this data should be interpreted with caution.

Naloxone is a medication that reverses the effects of opioid overdose. Naloxone is available free of charge at many pharmacies.

Note: Because of the way naloxone is disseminated in the community, published data now reports naloxone doses distributed. Previously published data reported naloxone kits distributed. One kit is equivalent to 2 doses. Additional community agencies also began reporting "people revived" information in 2019.
