Where and How to Dispose of Unused Medicines
Disposing of unused medicine in the household trash.
Almost all medicines can be thrown away safely in your household trash. Follow these steps.
Is your medicine cabinet full of expired drugs or medications you no longer use? Your medicine is for you. What’s safe for you might be harmful for someone else. You can dispose of your expired, unwanted, or unused medicines through a drug take back program — or you can do it at home.
