I think you’ll find it’s not that uncommon for them to deviate slightly from what was requested - although I’ll concede it’s more common for them to leave something out, that was requested, than to add anything - but as I said, it might have been his request that seemed “non-routine”, so if he had asked for less than is usual in these circumstances, they might have taken the initiative and decided to do the rest anyway. It’s actually less work for them than having to scan the patient again later, because the neuro realises he hadn’t asked for everything he needed.
Neuros aren’t infallible. Mine prescribed tablets for me last time. I got to the chemist with the prescription, only to be told: “I’m sorry, they don’t come as tablets in that dose - only the capsules. Will that be OK?”
OK, to you, me, most people maybe: tablet/capsule, what difference? But to the pharmacy, they definitely expected the prescription to say “capsules”, if it only comes as capsules, and queried why he was asking for something that did not exist! Luckily, they did not make me go all the way back and get a corrected prescription. I just said: “If that’s all it comes as, capsules will be fine!”
But technically, he should have known it isn’t manufactured in the form he prescribed. It only would have mattered if I’d needed to take half tablets, as obviously, you can cut a tablet, but not a capsule - all the contents would fall out. Luckily, he had only prescribed me whole ones - no half doses, so I didn’t need to worry that I wouldn’t be able to cut them up. Not the end of the world, but it just shows they sometimes request things that don’t make sense to the recipient, so the recipient either has to send it back with a query, or use their professional skill and judgement to work out what it should have said!
