Methadone blocks the brain's receptors that are affected by opiates such as oxycontin and other prescription drugs. This allows users to have a more gradual detox rather than the harsh, painful detox experienced without methadone.
Methadone reduces cravings and withdrawal symptoms during relapse. It also blocks the feelings of euphoria experienced with the use of heroin and other opiate drugs. Methadone is available in both pill form and as an oral solution. When taken as prescribed by a doctor, methadone can be used safely for years without any harsh side effects. The effects of methadone last from 24 to 36 hours, so one daily dose is effective for most patients.
