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