I got my repeat in January from the local pharmacy with no problems.
In the past, I have had problems with paper prescriptions because of 'quotas' which seems to be a small independent pharmacy problem. The last year or so I have been doing it online, then it is sent online from the GP and I give them plenty of time before I pick it up.
Now I am adding an extra week on to account for any brexity problems, so I will be re-ordering as soon as the online system says I can.
My old GP used to give me one box. I had to go there to order a repeat prescription because the online system would not let me do this within 3 months and then I had the pharmacy ordering problem, so I was often on the last tablet or worse

, (although the pharmacy found me a strip from an opened packet to tide me over once).
