Methadone detoxification is a process which must be overseen by drug addiction professionals within a drug rehab program who understand how challenging and difficult methadone detox can be. Methadone detox is regarded to be far more severe in terms of symptoms and duration than even heroin detox, and individuals often 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 should only be done under strict supervision at a drug rehab facility which has practical experience in handling this type of detox, and where the individual can receive further rehabilitation services to address all addiction issues.
