Medication Treatment: Methadone

What is Methadone?¹

• Methadone is a type of opioid that acts like an agonist in the brain.
• Methadone is different from opioids such as heroin or oxycodone, because instead of rapidly switching on physical changes and reactions, it activates opioid receptors in the brain very slowly over a long period of time which allows a person to stop going into withdrawal.
• Because methadone activates opioid receptors so slowly, it does not activate the rewarding/highly pleasurable sensations as strongly as other opioids do. This means that methadone has less risk for overuse compared to heroin or oxycodone. 
• Methadone does have more risk for overuse and physical side effects than buprenorphine, which is why it is carefully administered and regulated by the government.¹
• Unlike buprenorphine and naltrexone, a person does not have to be in withdrawal or opioid free to start methadone; it can be safely started at low doses at any time.¹
