| Medication Dose Consumed As Needed Indicator | Indicator | 0..1 | An indicator of whether the medication is or was or will be taken on an as-needed basis. |
| Medication Dose Consumed As Needed Reason Code | Codeable Concept | 0..1 | Uniquely specifies the symptom or condition that, when present, warrants taking the dose, according to the patient (e.g., fever, pain, dyspnea).
Note: Usually identical to the as-needed reason on the medication request(s); however, the patient may report (abnormally) an as-needed reason different from the one provided by the prescriber.
Value Set: https://fhir.infoway-inforoute.ca/ValueSet/clinicalfindingcode |
| Medication Consumption Route of Administration Code | Codeable Concept | 0..1 | Uniquely specifies the path by which the medication is or was or will be taken into or contacts the body (e.g., oral, intramuscular).
Value Set: https://fhir.infoway-inforoute.ca/ValueSet/routeofadministration |
| Medication Consumption Timing Code | Codeable Concept | 0..1 | Uniquely specifies the consumption frequency/timing of medication (e.g., BID, TID, QD).
Value Set: To be developed. |
| Medication Consumption Timing Frequency | Quantity | 0..1 | The frequency of the medication's consumption (e.g., 3 times per day) - value per time period (e.g., 3) and unit of measure for period duration (e.g., day).
Value: Integer (i.e., decimal part = 0)

| Medication Consumption Time of Day | Time | 0..* | The time of day(s) when the medication is or was or will be taken (e.g., 1300 hrs). |
| Medication Consumption Timing Day of Week Code | Codeable Concept | 0..* | Uniquely specifies the day of the week(s) when the medication is or was or will be taken (e.g., Tuesday).

| Medication Consumption Dosage Number of Repeats | Integer | 0..1 | The number of times the consumption of the medication dosage is or was or will be repeated. |
| Medication Usage Information Code | Codeable Concept | 0..* | Uniquely specifies actually followed or to-be-followed usage instruction(s) for the medication (e.g., with meals), or a warning that actually came to pass when the medication is or was taken (e.g., may cause drowsiness; in this context of medication statement, would mean that drowsiness upon medication consumption was actually reported).

| Medication Consumption Period | Period | 0..1 | The date and, if available, the time, when medication consumption was or will be started and (if available and applicable) stopped. |
