How should I dispose of leftover or expired medication?


Always dispose of old or expired medicines and leftover prescription medicines, since they may no longer be safe or effective. Check each medicine's label to find its expiration date. If you can't find the date on a prescription medicine, use the general rule that most expire one year after you get them. If you've had a prescription medicine for more than one year or aren't sure when you received it, play it safe: dispose of the medicine and get a new prescription. Dispose of any medicine that looks damaged, discolored, or otherwise different from the way it did when it was new. If you have any questions about whether your medicines are safe to take, ask your pharmacist or an appropriate medical professional.

The White House Office of National Drug Control Policy recommends the following guidelines for proper medication disposal as being safer and more environmentally friendly than flushing them down toilets or sinks:

  • Follow the specific disposal instructions on the drug label or patient information that accompanies the medication. Do not flush prescription drugs down the toilet unless this information specifically instructs you to do so. For further information on drugs that should be flushed visit the FDA’s website.

  • Take advantage of community pharmaceutical take-back programs that allow the public to bring unused drugs to a central location for proper disposal. Some communities have pharmaceutical take-back programs or community solid-waste programs that allow the public to bring unused drugs to a central location for proper disposal. Where these exist, they are a good way to dispose of unused pharmaceuticals.
  • If no instructions are given on the drug label and no take-back program is available in your area, throw the drugs in the household trash, but first:

    • Take unused, unneeded, or expired prescription drugs out of their original containers.
    • Mix prescription drugs (do NOT crush tablets or capsules) with an undesirable substance, such as kitty litter or used coffee grounds
    • Put mixture into an impermeable, non-descript, sealable container, such as empty margin tubs or sealable bags, to prevent the medication from leaking.
    • Remove personal information, including Rx number, on the empty prescription containers by covering them with black permanent marker, duct tape, or by scratching it off.
    • Throw the sealed containers with the mixtureand the empty drug containers in the trash. Take caution to make sure children or pets do not accidentally ingest expired medications that are thrown in the trash.
