Methadone detoxification is a process which should always be undertaken by drug rehab specialists in a drug and alcohol rehabilitation center that recognizes how serious and how much of a challenge methadone detoxification can be. Methadone detox is very often significantly more severe in terms of symptoms and length of time detoxing than even heroin detox, and individuals sometimes relapse back onto methadone to alleviate symptoms or even worse turn to heroin or prescription opioids to alleviate symptoms of withdrawal. For this reason methadone detox should only be undergone under close supervision at a Parkerfield drug treatment facility that has experience in handling this form of detox, and where the individual can take part in further rehab services to handle all substance abuse concerns.
