Prescriptions must be signed within how many days?

• A. 1 day
• B. 3 days
• C. 5 days
• D. 7 days

Answer: (B)

Signing within a short window after the prescription is written ensures the order is authentic and current. This quick validation by the prescriber provides a reliable authorization for the pharmacist to dispense, protects patient safety, and helps maintain accurate records. If the prescription isn’t signed within this timeframe, it can be considered invalid and may require renewal, reducing the risk of outdated therapy or forged or misused prescriptions.

The three-day limit balances practicality with safety—being long enough for patients to reach the prescriber or for a quick follow-up, but short enough to prevent changes in therapy or authority from going unchecked. Shorter like one day can be impractical, while longer like five or seven days increases the chance of the prescription becoming stale or compromised.
