"Other potential advantages of levomethadyl’s longer duration of action include reduced dispensing time and less opportunity for illegal diversion. Similar to methadone, it suppresses symptoms of withdrawal and produces cross-tolerance. Adverse effects of levomethadyl are infrequent and, when they occur, are the same as those for methadone. The average daily dose is 75 to 115 mg given 3 times per week. Treatment centers that are not open 7 d/wk dispense a larger dosage of levomethadyl before the 48-hour weekend period."
