Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehab facility who recognize how challenging and difficult methadone detoxification can be. Methadone detox 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 relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detox must only be done under strict supervision at a drug rehab facility which has practical experience in handling this type of detox, and where the person can receive further treatment services to address all addiction issues.
