Methadone detoxification is a process which must be supervised by drug addiction professionals within a drug rehab facility who understand how challenging and difficult methadone detoxification can be. Methadone detoxification is known to be far more serious 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 detoxification 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 further rehabilitation services to address all addiction issues.
