Most of the items are the 'just in case' medicines they supply when someone is coming to the end of their days. Mum only needed one of them, so all the rest were unused.
I can understand why this happens, as it means having the vials ready when the out of hours palliative team come out to the patient. They are drugs for nausea, agitation, pain and noisy breathing, and it is reassuring to know you have them. Mum had periods of severe agitation in the night on several occasions, so was given injections of the one prescribed for that. None of the others were needed, and I think they must be quite expensive.
I ordered Mum's repeat prescriptions for her over the last couple of years, so was able to make sure we didn't over order. In the past I've had changes in the type of insulin I am prescribed, and so often had vials or cartridges left over. There used to be an organisation who took these and sent them to (presumably hospitals or health services) in poorer countries. They no longer operate due (I think) to new rules. I know that insulin is very expensive and out of the reach of many people in the world; it just seemed awful to waste it.
