HEADS UP! Federal Gov pulling these from the shelves!

See the attached photo. Our local feedstore just got word these medicines will be no longer available as of June 11th (if your feed store has them on hand, they can be sold until gone)

There are some heavy hitters, so stock up.

As they announced two years ago.

Sadly, some of these have relatively short shelf lives.

Several items are no longer on the shelves at my local TSC.

I know it is something risky to speculate on, but is there a general consensus on how long a liquid antibiotic would be effective, after expiry, if kept refrigerated?

For the second time this week, I'm going to publicly answer "I don't know". I aced Colege Chem courses because I knew the material, not because I understood it well enough that I could have predicted the answers for myself, I merely knew where to find them. I could Do the work, just didn't grok the Why.

Here's what NIH has to say. Tl;dr? MANY drugs are mostly good (90% effective) a decade (or more) after their official expiration. Penicillin, and its analogs, generally have a shelf life of 2-3 years. Bad news? Insulin and liquid suspension antibiotics (yes, like Penicillin) are the least stable/most unreliable.
