How to dispose of medication
Don't flush most medications.
In recent years it has been discovered that flushing certain medications that contain hormones, antibiotics, and other substances can lead to contamination of groundwater and other detrimental effects. Instead of flushing these medications, the safest way to dispose of them is to disguise them and then throw them away with your trash.
Read the packaging on the medication and look for instructions on safe disposal. There are certain medications considered to be too potentially harmful to throw out with the trash.
