Personally, I feel that NO pills or medication should be kept by the bed. Should anyone be taking medications when they are groggy?
And please, THROW AWAY expired medications. The chemical composition of drugs can change and deteriorate over time and they should not be taken after they expire.
Lastly, if there is a chance of any children visiting your home, you should make a habit of never leaving medications out. All it takes is a moment of absent mindedness.
