System for administering a medicament

A system for recommending a dose of a medicament to a patient, comprising:

• a medicine delivery pen, comprising:
• a body structured to receive a vial of the medicament, the medicament including insulin;
• a dispensing mechanism capable of dispensing the medicament;
• a sensor capable of determining that the medicine delivery pen is being used and detecting a size of the dose being delivered;
• a processor capable of processing dose information;
• a power source that powers the processor;
• a memory capable of storing dose information;
• and
• a wireless transmitter capable of communicating with a separate companion device;
• and
• a computer program product residing in memory of the companion device, the computer program product comprising instructions, when executed by a process of the companion device, cause the system to implement steps (a)-(e):
• (a) determine a blood glucose level of the patient before an administration of insulin via the medicine delivery pen to define a determined blood glucose level;
• (b) determine a rate at which the blood glucose level of the patient is rising or falling before an administration of insulin to define a determined blood glucose trend, wherein the determined blood glucose trend is derived from a continuous blood glucose monitor that continuously monitors the blood glucose level of the patient;
• (c) based on the determined blood glucose level of step (a) and the determined blood glucose trend of step (b), automatically calculate a recommended dose of insulin to be administered to the patient;
• (d) visually present to the patient, via at least one of a display on the medicine delivery pen or a display on the companion device, the recommended dose of insulin to be administered to the patient;
• and
• (e) administer insulin to the patient via the medicine delivery pen in an amount equal to the recommended dose of insulin visually presented to the patient in step (d).
