Medication Disposal

What Should I Do With My Unused or Expired Medication(s)?

Unused and expired medications may be disposed safely at the following location:
Greenfield Law Enforcement Center
5300 W. Layton Avenue
This collection site is available for Greenfield residents and is open 8:00AM to 7:00PM daily.

Unused pharmaceuticals will ONLY be accepted in a clear plastic bag.  Empty unused pills from the container into a clear plastic bag and dispose of pill bottles or containers into your recycling bin or the garbage.  Zip-lock bags are available at the collection site. You do not have to take individual pills out of plastic pillow or bubble packaging.  
Liquids, creams and sprays (less than 4 oz.) can remain in the original leak proof container AND placed into a clear plastic bag.

NEVER flush or pour unused or expired medicine down the drain. Water reclamation facilities are not designed to remove all of them and trace amounts of pharmaceuticals are showing up in rivers and lakes around the world.

BRING:  Prescription and over-the-counter medications, ointments, patches, non-aerosol sprays, creams, vials and pet medications.

DO NOT BRING:  Illegal drugs, needles/sharps, inhalers, aerosol cans, bio-hazardous material (anything containing a bodily fluid or blood), personal care products (shampoo, soaps, lotions, sunscreens, etc.), household hazardous waste (paint, pesticides, oil, gas).

Do not flush expired or unused medication down the toilet. Flushing medication down the toilet is resulting in trace levels of chemicals commonly found in prescription drugs in our water supply. These chemicals may be harmful to fish and other wild life. Instead pharmaceutical experts recommend to:

Non-Greenfield Residents

  • Check with your local pharmacy to see if they will take back medications. (Walgreens has unused medication return envelopes for purchase)
  • Check if your local community has designated drop-off sites.
  • Dispose of medication in the garbage by taking these steps
    Keep the medication in its original container and scratch out your name for security purposes.
    Add a small amount of water to pills, or an absorbent material like flour to liquid medication to discourage their use.
    Put the containers in a paper bag or disposable food container like a yogurt or margarine container to conceal them. Toss in the garbage as close to your trash pick time as possible.
