A medicine dispensing device configured with an overdose indicator. The medicine dispensing device includes a substantially transparent vessel for holding a drug therein and a series of zones visible on the vessel. Each of the zones corresponds to a pre-determined dose of the drug. A first of the zones may correspond to a minimum dose of the drug for a patient population, a second of the zones may correspond to an average dose of the drug for the patient population, and a third of the zones may correspond to a maximum dose of the drug for the patient population and is marked or colored to serve as an overdose indicator. The series of zones may be printed on a label affixed to an outer surface of the vessel. Each zone may be of a different color.
