My OH is a cancer patient. We have tens of thousands of pounds of expensive prescription drugs that OH doesn't use, sat in our cupboards. One tablet costs over a thousand pounds per tablet according to the NHS website. He has 1 per month (expensive chemotherapy tablet) but the prescription is for 3 per month. Another chemo tablet costs £300 per tablet and he is prescribed 21 per month but only uses 11. That's on top of loads of other cheaper tablets he gets prescribed monthly but never uses such as anti-sickness, anti-diarrhoea, and also drugs he uses occasionally but gets a monthly supply every month such as omeprozol. That's at least £5,000 per month of drugs issued to him that he doesn't take!
So why don't you stop asking for them, I hear you say? He's tried, believe me, he's tried. Apparently it's an automatic prescription issued by the haematologist and the oncology dept. He doesn't "tick the boxes" like a normal GP prescription request. He's asked his consultant to reduce the quantity of drugs issued on the prescription - the consultant has said it's "too hard" to change as it's a pre-ordained, pre-approved treatment plan and would need some kind of permission from "whoever" approves his treatment, which would take a lot of time and even a meeting to get approval (apparently this is needed every time there's a change in treatment for long term cancer patients). Consultant glibly said "it's ok" because the oncology dept have got funding for the normal prescription so it's not costing them anything (the dept that is, not the NHS as a whole!). Pharmacy won't take them back to re-use and won't issue less than the prescription, so if he took them back to pharmacy, they'd destroy them).
We've pointed all this out to the consultant, who's reply was, just keep them and rotate them to stop them going out of date, as one day, "they", whoever "they" is, may stop authorising and paying for the treatment, so it would be handy to have plenty spare so OH could continue having the tablets for a while after his treatment officially stops!
The whole thing is madness. OH has been on this treatment regime for a few years now, and the last time we counted, we must have something like £40k of tablets in our cupboard! We're powerless to stop them being issued.
A bigger worry, though, is that on the NHS records, it will show him as having more tablets than he actually taking, so if he were admitted to hospital, or suffered some kind of medical emergency, his "records" aren't showing the true picture and unless he or I were able to tell the paramedics or doctors what tablets he was actually taking, wrong emergency treatment decisions could be taken!
