So again two situations. Normally bin them when out of date and replace as they are relatively cheap to replace. Some meds become less effective after a certain period of time and some would keep for 20 years past the Use by date. When producing medicines the company can never keep the conditions the drugs are made in sterile. Drugs are generally sensitive to light, temperature and moisture. The drug companies have a set time limit they can put on their drugs and because of that we do not really know if they are stable beyond that but logic would say yes they are. When I was in pharmacy, medicines information service, there were lots of inquiries about use by dates and the drug companies always returned the answer of 'not tested past those dates so we have no data to support an answer'.lee3 wrote:I knew I would want to pick your brains about something....I am pretty well stocked with over the counter shtuff and every now and then I go through the use by dates and replace as necessary..... However I don't bin the out of date items....I keep them....only for shtf situations....I am under the impression that these won't become harmfull as time passes...just possibly less effective?...what do you think
Thanks

SHTF keep them as they will come in handy and use them as you need to. Benefit and risk in medicine and I would say where the benefit outweighs the risk then use it (generally with the risk being it is less effective after the date rather than harmful). Some exceptions to that rule is Adrenaline and Glyceryl Trinitrate; very sensitive to heat and pretty much useless after a couple of months post use by date.
Again my opinion and what I would do but your choice in that situation.
