I have no problem with my repeat prescriptions but if I was you, I'd ring the chemist maybe an hour or the day before you go into collect them, just to remind them you are going in to collect or that you want them delivered. My prescription is always ready and the staff are great in pharmacy if they had a query about any of my meds, it would be sorted with Dr's before I get it and the pharmacist would explain what the difference is, I also get mine in little 'Vena link' packets, they're great, that way I don't forget to take any of my meds
