Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehab program who recognize how challenging and difficult methadone detoxification can be. Methadone detox is known to be far more severe 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 rehabilitation center which has experience in handling this type of detox, and where the person can receive further rehabilitation services to deal with all addiction issues.
