Methadone detoxification is a course of action which should always be undertaken by drug detox professionals in an alcohol and drug rehab facility that recognizes how difficult and how much of a challenge methadone detox can be. Methadone detoxification is known to be significantly more serious when considering symptoms and duration than even heroin detoxification, and individuals often go back to methadone to ease symptoms or even worse begin abusing heroin or medical pain relievers to relieve symptoms. This is why methadone detox should only be done under close supervision at a San Antonio drug detox facility that has experience in handling this form of detoxification, and where the person may receive further treatment services to address all substance abuse issues.
