Prescriptions (NHS, private & vet) needs to be dispensed within an appropriate time frame. All prescriptions: NHS, computer-generated, electronic (EPS), or handwritten must be dated. Prescriptions without a date are not legally valid and most likely will not be dispensed. Generally, the most important factor that affects the prescription expiry date is the presence of a controlled drug. So, how long does the prescription last? Read on.

I have an ‘owing’ for a controlled drug script? How much time do I have to collect it?

Occasionally in practice, you see party dispensed controlled drugs. For example, a part supply was made as the pharmacy did not have a complete quantity of a drug in stock.  In this case, an ‘owing ticket’ is typically produced to allow the patient to collect the remaining balance at different times. The remaining balance must be collected within 28 days of the script’s issue date.

How Long Does A Repeatable NHS Prescription Last?

How long does a repeatable NHS prescription last

Prescribed can choose to issue a 6-month or a 12-month repeatable prescription (paper or electronic) in some circumstances.

This concept is known as 'repeat dispensing' in the pharmacy. 

Patients who are issued a repeatable script do not need to see his/her GP to get another issue of the script.

A 12-month repeatable prescription expires 12 months from the issue date. The first supply of a repeatable prescription needs to be done within six months of the issue date. Controlled drugs Schedule 2 and 3 cannot be prescribed as a repeatable prescription.  As confusing as it may be, a list of drugs at the back of prescription is commonly known as ‘repeats.’ However, this has nothing to do with ‘repeat dispensing,’ about which I talked.
