Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehab program who understand how difficult and challenging methadone detoxification can be. Methadone detox is regarded 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 must only be done under strict supervision at a drug rehabilitation program which has practical experience in handling this type of detox, and where the individual can receive further treatment services to address all addiction issues.
