A clever new development in medicines packaging was profiled on Radio 4 You & Yours this afternoon.
As medicines in the prototype packaging reach their expiry date, the packaging degrades and an expiration message appears using international symbols of danger.
The inventors of this technology were interviewed along with RPS spokesperson Neal Patel, who gave advice on what happens to medicines when they reach their expiry date and the risks of taking them.
