Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehab program who understand how difficult and challenging methadone detoxification 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 relieve 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 rehabilitation center which has experience in dealing with this type of detoxification, and where the person can receive further recovery services to deal with all addiction issues.
