Medgadget: “Designers Kanupriya Goel and Gautam Goel propose a new design for pill blister packs that will display a message not to take the drugs once enough time passes. The material would consist of two layers, with the top containing the original drug’s info label and a bottom layer with ink that slowly seeps into the top. After enough time passes, the warning message will become clear and the patient will immediately know to get a fresh refill. The Self Expiring, as the design concept is called, won a 2013 red dot design award.”
From the reddot design award site: “Self Expiring is a packaging material for medicinal products that visually ‘self expires’ over a fixed period of time. This packaging will graphically display a ‘not fit for consumption’ message using universally accepted danger signs in regional languages. This solution will prevent illegal sales of expired medicines and fatalities arising from their consumption.”
Great concept. It would be cool if they could take it one step further and have the package analyze the medication inside and “expire” it when the potency goes below a pre-defined percentage. Expiration dates are good, but they don’t always tell the whole story.
