A calculated 
medicine dose dispensing apparatus includes a 
medicine bottle and a calculated 
dose medicine dispenser specific to the medicine 
bottle and a particular medicine. The medicine 
bottle has a neck and a 
bottle cap installed on the neck. The 
dose dispenser includes a cup in the shape of a truncated cone with a large 
diameter open end and an end wall closing the small 
diameter end. The end wall has a circular indent defined by an indent sidewall. The dose cup fits on the 
bottle cap with the large open end facing down and the 
bottle cap frictionally installed in the cup indent. A dial 
assembly is installed on the dose cup on the exterior of the end wall. The dial 
assembly calculates the proper dose of the medicine for the patient according to a patient parameter such as weight. The dial 
assembly includes a dial and a data disc. The data disc is installed on the dose cup end wall and carries at least two information sets that are circularly arranged, spaced apart information bits. Each information bit of one set is functionally related to an information bit of the other set, such as patient weight to medicine dose. The dial includes a dial plate installed over the data disc. The dial plate has one 
sight window corresponding to each information set. Rotation of the dial plate over the data disc displays functionally related information bits in the 
sight windows.
