Order any repeat prescriptions in advance to make sure you have enough over the Christmas period. Some pharmacies will be open for limited periods over the bank holidays or may be closed completely.
You can get some emergency prescriptions which will cover you for five days. You will only get one if it is a genuine emergency, it is not a controlled drug (e.g. morphine, pethidine, methadone), you go to the pharmacy in person and it is impossible to see your GP. Please note – there may be a charge for this.
