Methadone detoxification is a course of action which must be supervised by substance abuse professionals within a drug rehab center who understand how difficult and challenging methadone detoxification can be. Methadone detox is known to be far more severe in terms of symptoms and duration than even heroin detox, and users frequently revert back to methadone to relieve 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 rehabilitation 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.
