Methadone detoxification is a process which should be overseen by substance abuse professionals within a drug rehabilitation center who understand how difficult and challenging methadone detoxification can be. Methadone detoxification is known to be far more severe in terms of symptoms and duration than even heroin detox, and individuals frequently revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve 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 individual can receive additional treatment services to deal with all addiction issues.
