When it comes to medicines and food, the most important thing is correct storage.
And! always check goods for damage before storage.
In my experience, the following values are successful:
A temperature of approximately 10 °C to 16 °C;
dry with a humidity of around 50% to 65%;
dark, so not exposed to bright light, especially not UV;
dust-free and no grease haze.
A shelving system, clean cardboard/wooden boxes and a dehumidifier or dry packs promote long storage.
