Methadone detoxification is a course of action which must be supervised by substance abuse professionals within a drug rehab facility who understand 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 individuals typically revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detox must only be done under close supervision at a drug rehabilitation program which has practical experience in handling this type of detoxification, and where the individual can receive further recovery services to handle all addiction issues.
