I'm having similar issues where my prescription length is too long and if I waited until it ran out I'd have no strips, needles, lancets etc for days even a week at times. I have to order online sometimes just single items so I'm often at the pharmacy twice a weeks. Worst thing is they keep messing up my prescriptions and ordering things I don't need just because I haven't ordered them for a while. For example last week I ordered a new glucagon set, novorapid, a sharps box and needles. When I went to the pharmacy they said the prescription was made for glucose gels, sharps box and glargine. I had waited 4 days for this arrive and was running low. Called the doctors who then did it again 4 hours later but it was still wrong and half wasn't electronically sent over and I had to go to the doctors to get the paper prescription. They didn't give me needles so I orders again and they lost it so I ended up with just one needle left pleading down the phone to the receptionist to get doctor to sort it. I was told it would be later that evening before it was ready so I said it was unacceptable and that as I am pregnant they were endangering my baby. They had it ready in 20 minutes after that.
I've booked an appointment to discuss with the doctor. The pharmacist has been great and even once just gave me strips as the doctors said my prescription was locked in the system and wouldn't be resolved that day. I was out of strips so she just gave me them assuming that at some point the prescription would appear. Good job they know me as a very regular customer.
