Methadone detoxification is a process which must be supervised by drug addiction professionals within a drug rehabilitation facility who understand how challenging and difficult methadone detox can be. Methadone detox is known to be far more serious in terms of symptoms and duration than even heroin detox, and users often revert back to methadone to alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detox must only be done under close supervision at a drug rehab program which has practical experience in handling this type of detox, and where the person can receive further recovery services to address all addiction issues.
