The key here is to first think about where you’re storing your medicines. Moisture or heat can quickly reduce the validity of items. Therefore, above the fridge or higher shelves in the pantry are often the best storage areas. Most of us take our medicine in the kitchen so it makes sense to store them here.
Again, pull everything out, check for validity dates and group like with like items together. E.g. kid’s medicine vs prescription medicine etc. Give shelves a good wipe down before reloading. Avoid using containers with lids as this creates a barrier to accessing items easily.
