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