Methadone detoxification is a course of action which must be supervised by substance abuse professionals within a drug rehab program who recognize how challenging and difficult methadone detoxification can be. Methadone detox is regarded to be far more severe in terms of symptoms and duration than even heroin detox, and individuals often revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detoxification should only be done under strict supervision at a drug rehabilitation program which has experience in handling this type of detox, and where the individual can receive additional treatment services to address all addiction issues.
