Methadone detoxification is a course of action which must be supervised by drug addiction professionals within a drug rehab program who understand how challenging and difficult methadone detoxification can be. Methadone detoxification is regarded to be far more serious in terms of symptoms and duration than even heroin detox, and users often 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 should only be done under strict supervision at a drug rehabilitation center which has practical experience in handling this type of detox, and where the person can receive further treatment services to deal with all addiction issues.
