So much this.
What I had written was that a very close relative of mine used to run self funded volunteer medical clinics in an impoverished 3rd world nation and would bring volunteer nurses once or twice a year. They would go to pharmacies and manufactures of medicines in Canada and get expired stock donated for their trips . It wasn’t magically unsafe because it was newly expired. We just have very strict measures in place for safety and sales of medicines in Canada. Which is a good thing. But in this third would country these medicines saved lives . Their kids would die of things our kids get antibiotics for and go back to school after 48 hours . Sometimes our very strict quality measures can result in unnecessary waste.
So I’m not worried about the expiry personally . I truly believe it would not be extended or offered to us if it was unsafe to do so after the expiry date. We aren’t talking years , just four weeks.
