Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehabilitation center who understand 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 individuals typically revert back to methadone to ease 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 center which has experience in handling this type of detox, and where the person can receive additional rehabilitation services to deal with all addiction issues.
