Methadone detoxification is a course of action which must be overseen by addiction professionals within a drug rehab facility who understand how difficult and challenging methadone detox can be. Methadone detoxification is known to be far more severe 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 detoxification must only be done under close supervision at a drug rehab center which has experience in handling this type of detox, and where the individual can receive further rehabilitation services to handle all addiction issues.
