A serial prescription is a 24 or 56 week prescription for medicine(s) you need to treat a long-term condition. There is no need to request a repeat prescription form from your doctor during this time. Instead you only need to visit your registered pharmacy for your repeat medication while the serial prescription is still valid. Serial prescription(s) are kept in the pharmacy and your GP decides how often they should be collected, e.g. every four or eight weeks. Let your pharmacist know if you will need to collect your prescribed medicines earlier than normal or if you will need more than usual if, for example, you are going on holiday. Each time a prescription is collected the pharmacist notifies the doctor.
Serial prescriptions are only suitable for patients that are stable on their repeat medication and who will not have it regularly adjusted.
