The Opioid Replacement Therapy (sometimes called opioid agonist therapy) is an effective treatment for addiction to opioid drugs such as heroin, oxycodone, hydromorphone (Dilaudid), fentanyl and percocet.

The therapy involves taking the opioid agonists methadone (Methadose) or buprenorphine (Suboxone). These medications work to prevent withdrawal and reduce cravings for opioid drugs. People who are addicted to opioid drugs can take opioid replacement therapy to help stabilize their lives and to reduce the harms related to their drug use (CAMH, 2016).

Methadone and Suboxone treatment is available from the Ontario Addiction Treatment Centre (OATC) for individuals using opioids/narcotics, with two locations in Kitchener and one in Cambridge. For more information about accessing methadone treatment, use the above link or contact the OATC at 519-746-1919.

Towards Recovery clinics provide addiction medication treatment and support for individuals using street or prescription narcotics with an office located in Kitchener. Call 519-579-0589.

Rapid Access Addiction Clinics can also provide support with Opioid Replacement Therapy. Call 1-844-722-2977 for more information.
