On medication? The Message in a Bottle scheme might be of interest. The plastic bottles are available FREE from Neighbourhood Watch and inside you will find a small form where you list your medication plus two small green stickers.
The bottle then goes inside the fridge with a green sticker placed on the outside of the fridge.
The other green sticker is placed near the front door so if the Emergency Services are called and the occupier is unconscious or incoherent they will know where to look so that they can treat the patient immediately
