Methadone detoxification is a process which must be overseen by addiction professionals within a drug rehabilitation program who realize how challenging and difficult 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 relieve symptoms. This is why methadone detox must only be done under close supervision at a drug rehab center which has practical experience in dealing with this type of detoxification, and where the individual can receive further rehabilitation services to address all addiction issues.
