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