Frequently Asked Questions
Why do the medications on the list have flushing directions for disposal?
The medicines on this list of medicines recommended for disposal by flushing are safe and effective when used as prescribed, but they could be especially harmful to a child, pet, or anyone else if taken accidentally. Some of the possible harmful effects include breathing difficulties or heart problems, possibly leading to death. For these reasons, FDA advises that when it isn’t possible to return these medicines through a medicine take-back program, flushing these medicines down the sink or toilet is currently the best way to immediately and permanently remove the risk of harm from the home. FDA continues to work with and encourage the manufacturers of these medicines to develop alternative, safe disposal systems.
All other expired, unwanted, or unused medicines should be disposed of by using a medicine take-back program, if available, or by throwing them away in the household trash.
Does flushing the medicines on the list down the toilet or sink drain pose a risk to human health and the environment?
We are aware of recent reports that have noted trace amounts of medicines in the water system. The majority of medicines found in the water system are a result of the body’s natural routes of drug elimination (in urine or feces). Scientists, to date, have found no evidence of harmful effects to human health from medicines in the environment.
Disposal of these select, few medicines by flushing contributes only a small fraction of the total amount of medicine found in the water. When a medicine take-back program isn’t available, FDA believes that any potential risk to people and the environment from flushing this small, select list of medicines is outweighed by the real possibility of life-threatening risks from accidental ingestion of these medicines.
