 Methadone is available in traditional pill, sublingual tablet, and two different formulations designed for the person to drink.Drinkable forms include ready-to-dispense liquid (sold in the United States as Methadose), and "Diskets"(known on the street as "wafers" or "biscuits") which are tablets designed to disperse themselves rapidly in water for oral administration, used in a similar fashion to Alka-Seltzer.The liquid form is the most common as it allows for smaller dose changes.
