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