Drug expiration dating mixture
Here’s something about which I get calls all the time. There don’t seem to be any published reports of toxicity in people from drugs used after their expiration date, whether those drugs are injected, ingested, or put on the skin.You come out to the barn and you find that your horse has a bit of swollen leg. I found one report, back in 1963, of damage to a person’s kidneys from an outdated antibiotic product, but that product isn’t available anymore, and it wasn’t the antibiotic that caused the problem.That said, once you open the product up, the expiration date no longer applies. The manufacturer of my truck may recommend that I change the oil every 7,500 miles. The stability of drugs is something that has been studied a bit.
Generally, over-the-counter medicines should have a shelf life of around four or five years.
Most people give very little thought to the storage and shelf-life of over the counter medication, beyond keeping things out of the reach of children.
If you stock one or emergency medical kits, you may end up storing medications for longer periods of time.
You think, “I think that I’ll give him a couple of tablets of bute” – assuming you have some – because you think it might help with the soreness and swelling. Sadly, if you’re like me, your tack box is probably more like a time-capsule than it is an organized cabinet. That does make some sense, I mean, it’s not like your horse’s bute pills are going to morph into some poison – or explode – at any time after they expire.
Anyway, you dig through your tack box and finally find a bottle of bute under one of the assorted colors of mismatched leg bandages that you keep. So the expiration date doesn’t really mean that the medication has become unsafe to use. Drug safety in the United States is the responsibility of the Food and Drug Administration (FDA).
Expiration dates are chosen by the manufacturer based on three things: sales and marketing, legal protection and consumer protection. army would not have needed an expensive program to determine the actual shelf life of pharmaceutical drugs!
