| 1. Extension | |

| Control | 0..1 |
| Comments | Example: A prescriber instructs a patient to take 3 Tylenol 3 tablets every day as needed for pain for 90 days. However, the prescriber does not wish the patient to have more than 30 days supply at any given time so the prescriber instructs the pharmacist that the dispenseInterval is 30 days. The pharmacist then does 3 partial fills of 90 tablets (or 30 days supply) over the 90 day period. |
