If a patient has to wear one 100mcg duragesic fentanyl patch every 72hrs and is given a 30 day supply (10 patches) What is the soonest number of days after initial fill it can be refilled?
This problem does not say what day the patient started his medication. If he applied his patch on day 1 (of 30 day supply) it would be 30 days, or 30 days from date of rx.
