Final answer:
The question pertains to a health policy regarding the time limit for filling prescriptions, stating that if a prescription is not filled within 72 hours, a new one is needed.
Step-by-step explanation:
The information provided suggests that there is a time limit for a prescription to be filled. In this case, it's a 72-hour window before the prescription becomes invalid. If a pharmacy does not fill the prescription within this time frame, the patient must obtain a new prescription from their healthcare provider. It is important to understand such policies to ensure continuity of care and avoid interruptions in medication therapy. Matters concerning prescriptions, time frames for filling them, and the requirements for a new prescription if the time lapses are typically addressed within healthcare policy and pharmacy practice regulations.
