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