Can you use a metal lockable box to store medication in the fridge?
Yes, but it needs to be made out of metal that has been treated to not rust or is non-ferrous. High humidity in a refregerator will cause it to rust right through in a short amount of time. An alternative would be the top shelf for younger kids and severe punishment for older so your medicine stays safe. The threat of the Belt, there is nothing it can’t do.
