There was some discussion recently about different batches of drugs causing different side effects so I thought I would talk to my mate at the pharmacy when I collected my December party bag (Have you got yours organised?) . It seems that in MOST cases the manufacturer (generic or specific) makes no difference and it is a question of what stock is available. The one very important exception , however, is Diltiezem which was the drug in question . There are different formulations of this, with normal and modified/slow release and he told me that he always provided Tildiem Retard if the slow release version was prescribed. Adizem is not quite the same apparently. He assured me that in Lloyds at any rate, cost was not the driver, merely what the wholesaler has in stock in most cases. Our pharmacy is in the same complex as the medical centre but my repeats which are supposed to take max 72 hours often take much much longer, the last one taking nearly a week and a half and then I had to wait for it. When I was on zoladex as it costs about £80 a month they NEVER kept it in stock and always had to order it in. My understanding is that this is a cost saving measure so that should I die one month they are not left with unwanted items. Similar reason for only allowing one months supply at any one time. They won't give you three months in case you are hit by falling space debris and waste all that valuable stock. Don't you just love accountants?
PS just reminded of the Golgafrinchams in Hitchikers G to the U. A planet where all the accountants and phone sanitisers were sent as advance party to another world having been told that their own planet was about to be destroyed. LMAO
