Methadone detox is a procedure which should be overseen with the assistance of drug rehab professionals in a drug and alcohol rehab center that acknowledges how difficult and challenging methadone detoxification is. Methadone detoxification is very often significantly more severe when considering symptoms of withdrawal and duration than even heroin detoxification, and individuals often relapse back onto methadone to relieve symptoms or even worse turn to heroin or prescription pain relievers to relieve symptoms of withdrawal. For this reason methadone detoxification should only be undergone under close supervision at a San Fernando drug rehab that has experience in addressing this type of detox, and where the person can receive more extensive rehab methods to overcome all substance abuse problems.
